A dialog-box style window.

This class is a convenient way of creating a DocumentWindow with a close button that can be triggered by pressing the escape key.

Any of the methods available to a DocumentWindow or ResizableWindow are also available to this, so it can be made resizable, have a menu bar, etc.

You can either override or use an instance of the DialogWindow class directly, or you can use a DialogWindow::LaunchOptions structure to quickly set up and launch a box containing a content component.

If you use the class directly, you'll need to override the DocumentWindow::closeButtonPressed() method to handle the user clicking the close button - for more info, see the DocumentWindow help.

Constructor & Destructor Documentation

◆ DialogWindow()

DialogWindow::DialogWindow	(	const String &	name,
		Colour	backgroundColour,
		bool	escapeKeyTriggersCloseButton,
		bool	addToDesktop = `true`
	)

Creates a DialogWindow.

Parameters

name	the name to give the component - this is also the title shown at the top of the window. To change this later, use setName()
backgroundColour	the colour to use for filling the window's background.
escapeKeyTriggersCloseButton	if true, then pressing the escape key will cause the close button to be triggered
addToDesktop	if true, the window will be automatically added to the desktop; if false, you can use it as a child component

◆ ~DialogWindow()

DialogWindow::~DialogWindow ( )

Destructor.

If a content component has been set with setContentOwned(), it will be deleted.

Member Function Documentation

◆ activeWindowStatusChanged()

void ResizableWindow::activeWindowStatusChanged ( )

overrideprotectedvirtualinherited

Reimplemented from TopLevelWindow.

◆ addAndMakeVisible() [1/2]

void ResizableWindow::addAndMakeVisible	(	Component *	,
		int	zOrder = `-1`
	)

protectedinherited

Overridden to warn people about adding components directly to this component instead of using setContentOwned().

If you know what you're doing and are sure you really want to add a component, specify a base-class method call to Component::addAndMakeVisible(), to side-step this warning.

◆ addAndMakeVisible() [2/2]

void Component::addAndMakeVisible	(	Component &	child,
		int	zOrder = `-1`
	)

inherited

Adds a child component to this one, and also makes the child visible if it isn't already.

This is the same as calling setVisible (true) on the child and then addChildComponent(). See addChildComponent() for more details.

◆ addChildAndSetID()

void Component::addChildAndSetID	(	Component *	child,
		const String &	componentID
	)

inherited

Adds a child component to this one, makes it visible, and sets its component ID.

See also: addAndMakeVisible, addChildComponent

◆ addChildComponent() [1/2]

void ResizableWindow::addChildComponent	(	Component *	,
		int	zOrder = `-1`
	)

protectedinherited

Overridden to warn people about adding components directly to this component instead of using setContentOwned().

If you know what you're doing and are sure you really want to add a component, specify a base-class method call to Component::addAndMakeVisible(), to side-step this warning.

◆ addChildComponent() [2/2]

void Component::addChildComponent	(	Component &	child,
		int	zOrder = `-1`
	)

inherited

Adds a child component to this one.

Adding a child component does not mean that the component will own or delete the child - it's your responsibility to delete the component. Note that it's safe to delete a component without first removing it from its parent - doing so will automatically remove it and send out the appropriate notifications before the deletion completes.

If the child is already a child of this component, then no action will be taken, and its z-order will be left unchanged.

Parameters

child	the new component to add. If the component passed-in is already the child of another component, it'll first be removed from it current parent.
zOrder	The index in the child-list at which this component should be inserted. A value of -1 will insert it in front of the others, 0 is the back.

See also: removeChildComponent, addAndMakeVisible, addChildAndSetID, getChild, ComponentListener::componentChildrenChanged

◆ addComponentListener()

void Component::addComponentListener ( ComponentListener * newListener )

inherited

Adds a listener to be told about changes to the component hierarchy or position.

Component listeners get called when this component's size, position or children change - see the ComponentListener class for more details.

Parameters

newListener the listener to register - if this is already registered, it will be ignored.

See also: ComponentListener, removeComponentListener

◆ addKeyListener()

void Component::addKeyListener ( KeyListener * newListener )

inherited

Adds a listener that wants to hear about keypresses that this component receives.

The listeners that are registered with a component are called by its keyPressed() or keyStateChanged() methods (assuming these haven't been overridden to do something else).

If you add an object as a key listener, be careful to remove it when the object is deleted, or the component will be left with a dangling pointer.

See also: keyPressed, keyStateChanged, removeKeyListener

◆ addMouseListener()

void Component::addMouseListener	(	MouseListener *	newListener,
		bool	wantsEventsForAllNestedChildComponents
	)

inherited

Registers a listener to be told when mouse events occur in this component.

If you need to get informed about mouse events in a component but can't or don't want to override its methods, you can attach any number of listeners to the component, and these will get told about the events in addition to the component's own callbacks being called.

Note that a MouseListener can also be attached to more than one component.

Parameters

newListener	the listener to register
wantsEventsForAllNestedChildComponents	if true, the listener will receive callbacks for events that happen to any child component within this component, including deeply-nested child components. If false, it will only be told about events that this component handles.

See also: MouseListener, removeMouseListener

◆ addToDesktop() [1/2]

void TopLevelWindow::addToDesktop ( )

inherited

Adds the window to the desktop using the default flags.

◆ addToDesktop() [2/2]

void TopLevelWindow::addToDesktop	(	int	windowStyleFlags,
		void *	nativeWindowToAttachTo = `nullptr`
	)

overridevirtualinherited

Reimplemented from Component.

◆ alphaChanged()

virtual void Component::alphaChanged ( )

virtualinherited

Called when setAlpha() is used to change the alpha value of this component.

If you override this, you should also invoke the base class's implementation during your overridden function, as it performs some repainting behaviour.

Reimplemented in NSViewComponent.

◆ beginDragAutoRepeat()

static void Component::beginDragAutoRepeat ( int millisecondsBetweenCallbacks )

staticinherited

Ensures that a non-stop stream of mouse-drag events will be sent during the current mouse-drag operation.

This allows you to make sure that mouseDrag() events are sent continuously, even when the mouse isn't moving. This can be useful for things like auto-scrolling components when the mouse is near an edge.

Call this method during a mouseDown() or mouseDrag() callback, specifying the minimum interval between consecutive mouse drag callbacks. The callbacks will continue until the mouse is released, and then the interval will be reset, so you need to make sure it's called every time you begin a drag event. Passing an interval of 0 or less will cancel the auto-repeat.

See also: mouseDrag, Desktop::beginDragAutoRepeat

◆ broughtToFront()

virtual void Component::broughtToFront ( )

virtualinherited

Called when this component has been moved to the front of its siblings.

The component may have been brought to the front by the toFront() method, or by the operating system if it's a top-level window.

See also: toFront

Reimplemented in XEmbedComponent, and MultiDocumentPanelWindow.

◆ canModalEventBeSentToComponent()

virtual bool Component::canModalEventBeSentToComponent ( const Component * targetComponent )

virtualinherited

When a component is modal, this callback allows it to choose which other components can still receive events.

When a modal component is active and the user clicks on a non-modal component, this method is called on the modal component, and if it returns true, the event is allowed to reach its target. If it returns false, the event is blocked and the inputAttemptWhenModal() callback is made.

It called by the isCurrentlyBlockedByAnotherModalComponent() method. The default implementation just returns false in all cases.

◆ centreAroundComponent()

void TopLevelWindow::centreAroundComponent	(	Component *	componentToCentreAround,
		int	width,
		int	height
	)

inherited

This will set the bounds of the window so that it's centred in front of another window.

If your app has a few windows open and want to pop up a dialog box for one of them, you can use this to show it in front of the relevant parent window, which is a bit neater than just having it appear in the middle of the screen.

If componentToCentreAround is nullptr, then the currently active TopLevelWindow will be used instead. If no window is focused, it'll just default to the middle of the screen.

◆ centreWithSize()

void Component::centreWithSize	(	int	width,
		int	height
	)

inherited

Changes the component's size and centres it within its parent.

After changing the size, the component will be moved so that it's centred within its parent. If the component is on the desktop (or has no parent component), then it'll be centred within the main monitor area.

◆ childBoundsChanged()

void ResizableWindow::childBoundsChanged ( Component * )

overrideprotectedvirtualinherited

Reimplemented from Component.

◆ childrenChanged()

virtual void Component::childrenChanged ( )

virtualinherited

Subclasses can use this callback to be told when children are added or removed, or when their z-order changes.

See also: parentHierarchyChanged, ComponentListener::componentChildrenChanged

Reimplemented in DrawableComposite.

◆ clearContentComponent()

void ResizableWindow::clearContentComponent ( )

inherited

Removes the current content component.

If the previous content component was added with setContentOwned(), it will also be deleted. If it was added with setContentNonOwned(), it will simply be removed from this component.

◆ closeButtonPressed()

virtual void DocumentWindow::closeButtonPressed ( )

virtualinherited

This method is called when the user tries to close the window.

This is triggered by the user clicking the close button, or using some other OS-specific key shortcut or OS menu for getting rid of a window.

If the window is just a pop-up, you should override this closeButtonPressed() method and make it delete the window in whatever way is appropriate for your app. E.g. you might just want to call "delete this".

If your app is centred around this window such that the whole app should quit when the window is closed, then you will probably want to use this method as an opportunity to call JUCEApplicationBase::quit(), and leave the window to be deleted later by your JUCEApplicationBase::shutdown() method. (Doing it this way means that your window will still get cleaned-up if the app is quit by some other means (e.g. a cmd-Q on the mac or closing it via the taskbar icon on Windows).

(Note that the DocumentWindow class overrides Component::userTriedToCloseWindow() and redirects it to call this method, so any methods of closing the window that are caught by userTriedToCloseWindow() will also end up here).

Reimplemented in StandaloneFilterWindow, and MultiDocumentPanelWindow.

◆ colourChanged()

virtual void Component::colourChanged ( )

virtualinherited

This method is called when a colour is changed by the setColour() method.

See also: setColour, findColour

Reimplemented in Slider, TreeView, TextEditor, ListBox, ComboBox, Label, MidiKeyboardComponent, DrawableButton, ProgressBar, TextButton, GroupComponent, TextPropertyComponent, HyperlinkButton, and ToggleButton.

Referenced by ListBox::getHeaderComponent(), MidiKeyboardComponent::getOctaveForMiddleC(), and HyperlinkButton::getURL().

◆ contains()

bool Component::contains ( Point< int > localPoint )

inherited

Returns true if a given point lies within this component or one of its children.

Never override this method! Use hitTest to create custom hit regions.

Parameters

localPoint the coordinate to test, relative to this component's top-left.

Returns: true if the point is within the component's hit-test area, but only if that part of the component isn't clipped by its parent component. Note that this won't take into account any overlapping sibling components which might be in the way - for that, see reallyContains()

See also: hitTest, reallyContains, getComponentAt

◆ copyAllExplicitColoursTo()

void Component::copyAllExplicitColoursTo ( Component & target ) const

inherited

This looks for any colours that have been specified for this component, and copies them to the specified target component.

◆ createComponentSnapshot()

Image Component::createComponentSnapshot	(	Rectangle< int >	areaToGrab,
		bool	clipImageToComponentBounds = `true`,
		float	scaleFactor = `1.0f`
	)

inherited

Generates a snapshot of part of this component.

This will return a new Image, the size of the rectangle specified, containing a snapshot of the specified area of the component and all its children.

The image may or may not have an alpha-channel, depending on whether the image is opaque or not.

If the clipImageToComponentBounds parameter is true and the area is greater than the size of the component, it'll be clipped. If clipImageToComponentBounds is false then parts of the component beyond its bounds can be drawn.

See also: paintEntireComponent

◆ createFocusTraverser()

virtual KeyboardFocusTraverser* Component::createFocusTraverser ( )

virtualinherited

Creates a KeyboardFocusTraverser object to use to determine the logic by which focus should be passed from this component.

The default implementation of this method will return a default KeyboardFocusTraverser if this component is a focus container (as determined by the setFocusContainer() method). If the component isn't a focus container, then it will recursively ask its parents for a KeyboardFocusTraverser.

If you overrride this to return a custom KeyboardFocusTraverser, then this component and all its sub-components will use the new object to make their focusing decisions.

The method should return a new object, which the caller is required to delete when no longer needed.

Reimplemented in Label, and FilenameComponent.

◆ deleteAllChildren()

void Component::deleteAllChildren ( )

inherited

Removes and deletes all of this component's children.

My advice is to avoid this method! It's an old function that is only kept here for backwards-compatibility with legacy code, and should be viewed with extreme suspicion by anyone attempting to write modern C++. In almost all cases, it's much smarter to manage the lifetimes of your child components via modern RAII techniques such as simply making them member variables, or using ScopedPointer, OwnedArray, etc to manage their lifetimes appropriately.

See also: removeAllChildren

◆ enablementChanged()

virtual void Component::enablementChanged ( )

virtualinherited

Callback to indicate that this component has been enabled or disabled.

This can be triggered by one of the component's parent components being enabled or disabled, as well as changes to the component itself.

The default implementation of this method does nothing; your class may wish to repaint itself or something when this happens.

See also: setEnabled, isEnabled

Reimplemented in Slider, TreeView, TextEditor, Button, ComboBox, Label, DrawableButton, PropertyComponent, GroupComponent, and ToolbarButton.

Referenced by PropertyComponent::setPreferredHeight().

◆ enterModalState()

void Component::enterModalState	(	bool	takeKeyboardFocus = `true`,
		ModalComponentManager::Callback *	callback = `nullptr`,
		bool	deleteWhenDismissed = `false`
	)

inherited

Puts the component into a modal state.

This makes the component modal, so that messages are blocked from reaching any components other than this one and its children, but unlike runModalLoop(), this method returns immediately.

If takeKeyboardFocus is true, the component will use grabKeyboardFocus() to get the focus, which is usually what you'll want it to do. If not, it will leave the focus unchanged.

The callback is an optional object which will receive a callback when the modal component loses its modal status, either by being hidden or when exitModalState() is called. If you pass an object in here, the system will take care of deleting it later, after making the callback

If deleteWhenDismissed is true, then when it is dismissed, the component will be deleted and then the callback will be called. (This will safely handle the situation where the component is deleted before its exitModalState() method is called).

See also: exitModalState, runModalLoop, ModalComponentManager::attachCallback

◆ escapeKeyPressed()

virtual bool DialogWindow::escapeKeyPressed ( )

virtual

Called when the escape key is pressed.

This can be overridden to do things other than the default behaviour, which is to hide the window. Return true if the key has been used, or false if it was ignored.

◆ exitModalState()

void Component::exitModalState ( int returnValue )

inherited

Ends a component's modal state.

If this component is currently modal, this will turn off its modalness, and return a value to the runModalLoop() method that might have be running its modal loop.

See also: runModalLoop, enterModalState, isCurrentlyModal

◆ findChildWithID()

Component* Component::findChildWithID ( StringRef componentID ) const

noexceptinherited

Looks for a child component with the specified ID.

See also: setComponentID, getComponentID

◆ findColour()

Colour Component::findColour	(	int	colourId,
		bool	inheritFromParent = `false`
	)		const

inherited

Looks for a colour that has been registered with the given colour ID number.

If a colour has been set for this ID number using setColour(), then it is returned. If none has been set, the method will try calling the component's LookAndFeel class's findColour() method. If none has been registered with the look-and-feel either, it will just return black.

The colour IDs for various purposes are stored as enums in the components that they are relevant to - for an example, see Slider::ColourIds, Label::ColourIds, TextEditor::ColourIds, TreeView::ColourIds, etc.

See also: setColour, isColourSpecified, colourChanged, LookAndFeel::findColour, LookAndFeel::setColour

◆ findParentComponentOfClass()

template<class TargetClass >

TargetClass* Component::findParentComponentOfClass ( ) const

inlineinherited

Searches the parent components for a component of a specified class.

For example findParentComponentOfClass <MyComp>() would return the first parent component that can be dynamically cast to a MyComp, or will return nullptr if none of the parents are suitable.

◆ focusGained()

virtual void Component::focusGained ( FocusChangeType cause )

virtualinherited

Called to indicate that this component has just acquired the keyboard focus.

See also: focusLost, setWantsKeyboardFocus, getCurrentlyFocusedComponent, hasKeyboardFocus

Reimplemented in TextEditor, Button, ComboBox, CodeEditorComponent, Label, WebBrowserComponent, and XEmbedComponent.

◆ focusLost()

virtual void Component::focusLost ( FocusChangeType cause )

virtualinherited

Called to indicate that this component has just lost the keyboard focus.

See also: focusGained, setWantsKeyboardFocus, getCurrentlyFocusedComponent, hasKeyboardFocus

Reimplemented in TextEditor, Button, ComboBox, CodeEditorComponent, MidiKeyboardComponent, and XEmbedComponent.

Referenced by MidiKeyboardComponent::getOctaveForMiddleC().

◆ focusOfChildComponentChanged()

void TopLevelWindow::focusOfChildComponentChanged ( FocusChangeType )

overrideprotectedvirtualinherited

Reimplemented from Component.

◆ getActiveTopLevelWindow()

static TopLevelWindow* TopLevelWindow::getActiveTopLevelWindow ( )

staticnoexceptinherited

Returns the currently-active top level window.

There might not be one, of course, so this can return nullptr.

◆ getAlpha()

float Component::getAlpha ( ) const

noexceptinherited

Returns the component's current transparancy level.

See setAlpha() for more details.

◆ getBackgroundColour()

Colour ResizableWindow::getBackgroundColour ( ) const

noexceptinherited

Returns the colour currently being used for the window's background.

As a convenience the window will fill itself with this colour, but you can override the paint() method if you need more customised behaviour.

This method is the same as retrieving the colour for ResizableWindow::backgroundColourId.

See also: setBackgroundColour

◆ getBorderThickness()

virtual BorderSize<int> ResizableWindow::getBorderThickness ( )

virtualinherited

Returns the width of the frame to use around the window.

See also: getContentComponentBorder

◆ getBottom()

int Component::getBottom ( ) const

inlinenoexceptinherited

Returns the y coordinate of the bottom edge of this component.

This is a distance in pixels from the top edge of the component's parent.

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to its bounding box.

◆ getBounds()

Rectangle<int> Component::getBounds ( ) const

inlinenoexceptinherited

Returns this component's bounding box.

The rectangle returned is relative to the top-left of the component's parent.

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to its bounding box.

◆ getBoundsInParent()

Rectangle<int> Component::getBoundsInParent ( ) const

noexceptinherited

Returns the area of this component's parent which this component covers.

The returned area is relative to the parent's coordinate space. If the component has an affine transform specified, then the resulting area will be the smallest rectangle that fully covers the component's transformed bounding box. If this component has no parent, the return value will simply be the same as getBounds().

◆ getCachedComponentImage()

CachedComponentImage* Component::getCachedComponentImage ( ) const

inlinenoexceptinherited

Returns the object that was set by setCachedComponentImage().

See also: setCachedComponentImage

◆ getChildComponent()

Component* Component::getChildComponent ( int index ) const

noexceptinherited

Returns one of this component's child components, by it index.

The component with index 0 is at the back of the z-order, the one at the front will have index (getNumChildComponents() - 1).

If the index is out-of-range, this will return a null pointer.

See also: getChildren, getNumChildComponents, getIndexOfChildComponent

◆ getChildren()

const Array<Component*>& Component::getChildren ( ) const

inlinenoexceptinherited

Provides access to the underlying array of child components.

The most likely reason you may want to use this is for iteration in a range-based for loop.

Referenced by componentPeerAboutToChange().

◆ getCloseButton()

Button* DocumentWindow::getCloseButton ( ) const

noexceptinherited

Returns the close button, (or nullptr if there isn't one).

◆ getComponentAt() [1/2]

Component* Component::getComponentAt	(	int	x,
		int	y
	)

inherited

Returns the component at a certain point within this one.

Parameters

x	the x coordinate to test, relative to this component's left edge.
y	the y coordinate to test, relative to this component's top edge.

Returns: the component that is at this position - which may be 0, this component, or one of its children. Note that overlapping siblings that might actually be in the way are not taken into account by this method - to account for these, instead call getComponentAt on the top-level parent of this component.

See also: hitTest, contains, reallyContains

◆ getComponentAt() [2/2]

Component* Component::getComponentAt ( Point< int > position )

inherited

Returns the component at a certain point within this one.

Parameters

position the coordinate to test, relative to this component's top-left.

Returns: the component that is at this position - which may be 0, this component, or one of its children. Note that overlapping siblings that might actually be in the way are not taken into account by this method - to account for these, instead call getComponentAt on the top-level parent of this component.

const String& Component::getComponentID ( ) const

inlinenoexceptinherited

Returns the ID string that was set by setComponentID().

◆ getConstrainer()

ComponentBoundsConstrainer* ResizableWindow::getConstrainer ( )

inlinenoexceptinherited

Returns the bounds constrainer object that this window is using.

You can access this to change its properties.

◆ getContentComponent()

Component* ResizableWindow::getContentComponent ( ) const

inlinenoexceptinherited

Returns the current content component.

This will be the component set by setContentOwned() or setContentNonOwned, or nullptr if none has yet been specified.

See also: setContentOwned, setContentNonOwned

◆ getContentComponentBorder()

virtual BorderSize<int> ResizableWindow::getContentComponentBorder ( )

virtualinherited

Returns the insets to use when positioning the content component.

See also: getBorderThickness

◆ getCurrentlyFocusedComponent()

static Component* Component::getCurrentlyFocusedComponent ( )

staticnoexceptinherited

Returns the component that currently has the keyboard focus.

Returns: the focused component, or null if nothing is focused.

◆ getCurrentlyModalComponent()

static Component* Component::getCurrentlyModalComponent ( int index = 0 )

staticnoexceptinherited

Returns one of the components that are currently modal.

The index specifies which of the possible modal components to return. The order of the components in this list is the reverse of the order in which they became modal - so the component at index 0 is always the active component, and the others are progressively earlier ones that are themselves now blocked by later ones.

Returns: the modal component, or null if no components are modal (or if the index is out of range)

See also: getNumCurrentlyModalComponents, runModalLoop, isCurrentlyModal

◆ getDesktopScaleFactor()

virtual float Component::getDesktopScaleFactor ( ) const

virtualinherited

Returns the default scale factor to use for this component when it is placed on the desktop.

The default implementation of this method just returns the value from Desktop::getGlobalScaleFactor(), but it can be overridden if a particular component has different requirements. The method only used if this component is added to the desktop - it has no effect for child components.

Referenced by JuceGLView::layerClass, OpenGLContext::NativeContext::NativeContext(), and CarbonViewWrapperComponent::setEmbeddedWindowToOurSize().

◆ getDesktopWindowStyleFlags()

int ResizableWindow::getDesktopWindowStyleFlags ( ) const

overrideprotectedvirtualinherited

Reimplemented from TopLevelWindow.

◆ getExplicitFocusOrder()

int Component::getExplicitFocusOrder ( ) const

inherited

Returns the focus order of this component, if one has been specified.

By default components don't have a focus order - in that case, this will return 0. Lower numbers indicate that the component will be earlier in the focus traversal order.

To change the order, call setExplicitFocusOrder().

The focus order may be used by the KeyboardFocusTraverser class as part of its algorithm for deciding the order in which components should be traversed. See the KeyboardFocusTraverser class for more details on this.

◆ getHeight()

int Component::getHeight ( ) const

inlinenoexceptinherited

Returns the component's height in pixels.

◆ getIndexOfChildComponent()

int Component::getIndexOfChildComponent ( const Component * child ) const

noexceptinherited

Returns the index of this component in the list of child components.

A value of 0 means it is first in the list (i.e. behind all other components). Higher values are further towards the front.

Returns -1 if the component passed-in is not a child of this component.

◆ getInterceptsMouseClicks()

void Component::getInterceptsMouseClicks	(	bool &	allowsClicksOnThisComponent,
		bool &	allowsClicksOnChildComponents
	)		const

noexceptinherited

Retrieves the current state of the mouse-click interception flags.

On return, the two parameters are set to the state used in the last call to setInterceptsMouseClicks().

See also: setInterceptsMouseClicks

◆ getLocalArea()

Rectangle<int> Component::getLocalArea	(	const Component *	sourceComponent,
		Rectangle< int >	areaRelativeToSourceComponent
	)		const

inherited

Converts a rectangle to be relative to this component's coordinate space.

This takes a rectangle that is relative to a different component, and returns its position relative to this component. If the sourceComponent parameter is null, the source rectangle is assumed to be a screen coordinate.

If you've used setTransform() to apply one or more transforms to components, then the source rectangle may not actually be rectanglular when converted to the target space, so in that situation this will return the smallest rectangle that fully contains the transformed area.

Referenced by OpenGLContext::NativeContext::NativeContext().

◆ getLocalBounds()

Rectangle<int> Component::getLocalBounds ( ) const

noexceptinherited

Returns the component's bounds, relative to its own origin.

This is like getBounds(), but returns the rectangle in local coordinates, In practice, it'll return a rectangle with position (0, 0), and the same size as this component.

Referenced by OpenGLContext::NativeContext::NativeContext().

◆ getLocalPoint() [1/2]

Point<int> Component::getLocalPoint	(	const Component *	sourceComponent,
		Point< int >	pointRelativeToSourceComponent
	)		const

inherited

Converts a point to be relative to this component's coordinate space.

This takes a point relative to a different component, and returns its position relative to this component. If the sourceComponent parameter is null, the source point is assumed to be a global screen coordinate.

◆ getLocalPoint() [2/2]

Point<float> Component::getLocalPoint	(	const Component *	sourceComponent,
		Point< float >	pointRelativeToSourceComponent
	)		const

inherited

Converts a point to be relative to this component's coordinate space.

This takes a point relative to a different component, and returns its position relative to this component. If the sourceComponent parameter is null, the source point is assumed to be a global screen coordinate.

◆ getLookAndFeel()

LookAndFeel& Component::getLookAndFeel ( ) const

noexceptinherited

Finds the appropriate look-and-feel to use for this component.

If the component hasn't had a look-and-feel explicitly set, this will return the parent's look-and-feel, or just the default one if there's no parent.

See also: setLookAndFeel, lookAndFeelChanged

Referenced by StandalonePluginHolder::showAudioSettingsDialog().

◆ getMarkers()

virtual MarkerList* Component::getMarkers ( bool xAxis )

virtualinherited

Components can implement this method to provide a MarkerList.

The default implementation of this method returns nullptr, but you can override it to return a pointer to the component's marker list. If xAxis is true, it should return the X marker list; if false, it should return the Y markers.

Reimplemented in DrawableComposite.

◆ getMaximiseButton()

Referenced by CarbonViewWrapperComponent::getOwnerWindow().

◆ getWindowStateAsString()

String ResizableWindow::getWindowStateAsString ( )

inherited

Returns a string which encodes the window's current size and position.

This string will encapsulate the window's size, position, and whether it's in full-screen mode. It's intended for letting your application save and restore a window's position.

Use the restoreWindowStateFromString() to restore from a saved state.

◆ getX()

int Component::getX ( ) const

inlinenoexceptinherited

Returns the x coordinate of the component's left edge.

This is a distance in pixels from the left edge of the component's parent.

◆ grabKeyboardFocus()

void Component::grabKeyboardFocus ( )

inherited

Tries to give keyboard focus to this component.

When the user clicks on a component or its grabKeyboardFocus() method is called, the following procedure is used to work out which component should get it:

if the component that was clicked on actually wants focus (as indicated by calling getWantsKeyboardFocus), it gets it.
if the component itself doesn't want focus, it will try to pass it on to whichever of its children is the default component, as determined by KeyboardFocusTraverser::getDefaultComponent()
if none of its children want focus at all, it will pass it up to its parent instead, unless it's a top-level component without a parent, in which case it just takes the focus itself.

Important note! It's obviously not possible for a component to be focused unless it's actually visible, on-screen, and inside a window that is also visible. So there's no point trying to call this in the component's own constructor or before all of its parent hierarchy has been fully instantiated.

See also: setWantsKeyboardFocus, getWantsKeyboardFocus, hasKeyboardFocus, getCurrentlyFocusedComponent, focusGained, focusLost, keyPressed, keyStateChanged

◆ handleCommandMessage()

virtual void Component::handleCommandMessage ( int commandId )

virtualinherited

This is called by the message thread when a command message arrives, and the component can override this method to process it in any way it needs to.

See also: postCommandMessage

Reimplemented in TextEditor, Button, CallOutBox, OpenGLContext::NativeContext::DummyComponent, MenuBarComponent, and OpenGLContext::NativeContext::DummyComponent.

◆ hasKeyboardFocus()

bool Component::hasKeyboardFocus ( bool trueIfChildIsFocused ) const

inherited

Returns true if this component currently has the keyboard focus.

Parameters

trueIfChildIsFocused if this is true, then the method returns true if either this component or any of its children (recursively) have the focus. If false, the method only returns true if this component has the focus.

See also: grabKeyboardFocus, setWantsKeyboardFocus, getCurrentlyFocusedComponent, focusGained, focusLost

◆ hitTest()

virtual bool Component::hitTest	(	int	x,
		int	y
	)

virtualinherited

Tests whether a given point is inside the component.

Overriding this method allows you to create components which only intercept mouse-clicks within a user-defined area.

This is called to find out whether a particular x, y coordinate is considered to be inside the component or not, and is used by methods such as contains() and getComponentAt() to work out which component the mouse is clicked on.

Components with custom shapes will probably want to override it to perform some more complex hit-testing.

The default implementation of this method returns either true or false, depending on the value that was set by calling setInterceptsMouseClicks() (true is the default return value).

Note that the hit-test region is not related to the opacity with which areas of a component are painted.

Applications should never call hitTest() directly - instead use the contains() method, because this will also test for occlusion by the component's parent.

Note that for components on the desktop, this method will be ignored, because it's not always possible to implement this behaviour on all platforms.

Parameters

x	the x coordinate to test, relative to the left hand edge of this component. This value is guaranteed to be greater than or equal to zero, and less than the component's width
y	the y coordinate to test, relative to the top edge of this component. This value is guaranteed to be greater than or equal to zero, and less than the component's height

Returns: true if the click is considered to be inside the component

◆ inputAttemptWhenModal()

virtual void Component::inputAttemptWhenModal ( )

virtualinherited

Called when the user tries to click on a component that is blocked by another modal component.

When a component is modal and the user clicks on one of the other components, the modal component will receive this callback.

The default implementation of this method will play a beep, and bring the currently modal component to the front, but it can be overridden to do other tasks.

See also: isCurrentlyBlockedByAnotherModalComponent, canModalEventBeSentToComponent

Reimplemented in Label, and CallOutBox.

◆ isActiveWindow()

bool TopLevelWindow::isActiveWindow ( ) const

inlinenoexceptinherited

True if this is currently the TopLevelWindow that is actively being used.

This isn't quite the same as having keyboard focus, because the focus may be on a child component or a temporary pop-up menu, etc, while this window is still considered to be active.

See also: activeWindowStatusChanged

◆ isAlwaysOnTop()

bool Component::isAlwaysOnTop ( ) const

noexceptinherited

Returns true if this component is set to always stay in front of its siblings.

See also: setAlwaysOnTop

◆ isBroughtToFrontOnMouseClick()

See also: setBroughtToFrontOnMouseClick

◆ isColourSpecified()

bool Component::isColourSpecified ( int colourId ) const

inherited

Returns true if the specified colour ID has been explicitly set for this component using the setColour() method.

◆ isCurrentlyBlockedByAnotherModalComponent()

bool Component::isCurrentlyBlockedByAnotherModalComponent ( ) const

inherited

Checks whether there's a modal component somewhere that's stopping this one from receiving messages.

If there is a modal component, its canModalEventBeSentToComponent() method will be called to see if it will still allow this component to receive events.

See also: runModalLoop, getCurrentlyModalComponent

◆ isCurrentlyModal()

bool Component::isCurrentlyModal ( bool onlyConsiderForemostModalComponent = true ) const

noexceptinherited

Returns true if this component is the modal one.

It's possible to have nested modal components, e.g. a pop-up dialog box that launches another pop-up. If onlyConsiderForemostModalComponent is true then isCurrentlyModal will only return true for the one at the top of the stack. If onlyConsiderForemostModalComponent is false then isCurrentlyModal will return true for any modal component in the stack.

◆ isDropShadowEnabled()

bool TopLevelWindow::isDropShadowEnabled ( ) const

inlinenoexceptinherited

True if drop-shadowing is enabled.

References Component::addToDesktop(), Component::focusOfChildComponentChanged(), Component::parentHierarchyChanged(), and Component::visibilityChanged().

◆ isEnabled()

bool Component::isEnabled ( ) const

noexceptinherited

Returns true if the component (and all its parents) are enabled.

Components are enabled by default, and can be disabled with setEnabled(). Exactly what difference this makes to the component depends on the type. E.g. buttons and sliders will choose to draw themselves differently, etc.

Note that if one of this component's parents is disabled, this will always return false, even if this component itself is enabled.

See also: setEnabled, enablementChanged

◆ isFocusContainer()

bool Component::isFocusContainer ( ) const

noexceptinherited

◆ isMinimised()

bool ResizableWindow::isMinimised ( ) const

inherited

Returns true if the window is currently minimised.

See also: setMinimised

◆ isMouseButtonDown()

bool Component::isMouseButtonDown ( ) const

inherited

Returns true if the mouse button is currently held down in this component.

Note that this is a test to see whether the mouse is being pressed in this component, so it'll return false if called on component A when the mouse is actually being dragged in component B.

See also: isMouseButtonDownAnywhere, isMouseOver, isMouseOverOrDragging

◆ isMouseButtonDownAnywhere()

static bool Component::isMouseButtonDownAnywhere ( )

staticnoexceptinherited

Returns true if a mouse button is currently down.

Unlike isMouseButtonDown, this will test the current state of the buttons without regard to which component (if any) it has been pressed in.

See also: isMouseButtonDown, ModifierKeys

◆ isMouseOver()

bool Component::isMouseOver ( bool includeChildren = false ) const

inherited

Returns true if the mouse is currently over this component.

If the mouse isn't over the component, this will return false, even if the mouse is currently being dragged - so you can use this in your mouseDrag method to find out whether it's really over the component or not.

Note that when the mouse button is being held down, then the only component for which this method will return true is the one that was originally clicked on.

If includeChildren is true, then this will also return true if the mouse is over any of the component's children (recursively) as well as the component itself.

See also: isMouseButtonDown. isMouseOverOrDragging, mouseDrag

◆ isMouseOverOrDragging()

bool Component::isMouseOverOrDragging ( bool includeChildren = false ) const

inherited

True if the mouse is over this component, or if it's being dragged in this component.

This is a handy equivalent to (isMouseOver() || isMouseButtonDown()).

See also: isMouseOver, isMouseButtonDown, isMouseButtonDownAnywhere

◆ isOnDesktop()

bool Component::isOnDesktop ( ) const

noexceptinherited

Returns true if this component is currently showing on the desktop.

See also: setUsingNativeTitleBar

◆ isVisible()

bool Component::isVisible ( ) const

inlinenoexceptinherited

this doesn't necessarily tell you whether this comp is actually on the screen because this depends on whether all the parent components are also visible - use isShowing() to find this out.

See also: isShowing, setVisible

◆ keyPressed()

bool DialogWindow::keyPressed ( const KeyPress & )

overrideprotectedvirtual

Reimplemented from Component.

◆ keyStateChanged()

virtual bool Component::keyStateChanged ( bool isKeyDown )

virtualinherited

Called when a key is pressed or released.

Whenever a key on the keyboard is pressed or released (including modifier keys like shift and ctrl), this method will be called on the component that currently has the keyboard focus. Remember that a component will only be given the focus if its setWantsKeyboardFocus() method has been used to enable this.

If your implementation returns true, the event will be consumed and not passed on to any other listeners. If it returns false, then any KeyListeners that have been registered with this component will have their keyStateChanged methods called. As soon as one of these returns true, the process will stop, but if they all return false, the event will be passed upwards to this component's parent, and so on.

The default implementation of this method does nothing and returns false.

To find out which keys are up or down at any time, see the KeyPress::isKeyCurrentlyDown() method.

Parameters

isKeyDown true if a key has been pressed; false if it has been released

See also: keyPressed, KeyPress, getCurrentlyFocusedComponent, addKeyListener

Referenced by ListBox::getHeaderComponent(), MidiKeyboardComponent::getOctaveForMiddleC(), and Button::LookAndFeelMethods::~LookAndFeelMethods().

◆ localAreaToGlobal()

Rectangle<int> Component::localAreaToGlobal ( Rectangle< int > localArea ) const

inherited

Converts a rectangle from this component's coordinate space to a screen coordinate.

If you've used setTransform() to apply one or more transforms to components, then the source rectangle may not actually be rectanglular when converted to the target space, so in that situation this will return the smallest rectangle that fully contains the transformed area.

See also: getLocalPoint, localPointToGlobal

◆ localPointToGlobal() [1/2]

Point<int> Component::localPointToGlobal ( Point< int > localPoint ) const

◆ modifierKeysChanged()

virtual void Component::modifierKeysChanged ( const ModifierKeys & modifiers )

virtualinherited

Called when a modifier key is pressed or released.

Whenever the shift, control, alt or command keys are pressed or released, this method will be called on the component that currently has the keyboard focus. Remember that a component will only be given the focus if its setWantsKeyboardFocus() method has been used to enable this.

The default implementation of this method actually calls its parent's modifierKeysChanged method, so that focused components which aren't interested in this will give their parents a chance to act on the event instead.

See also: keyStateChanged, ModifierKeys

Reimplemented in Slider.

◆ mouseDoubleClick()

virtual void Component::mouseDoubleClick ( const MouseEvent & event )

overridevirtualinherited

Called when a mouse button has been double-clicked on a component.

The MouseEvent object passed in contains lots of methods for finding out which button was pressed, as well as which modifier keys (e.g. shift, ctrl) were held down at the time.

Parameters

event details about the position and status of the mouse event, including the source component in which it occurred

See also: mouseDown, mouseUp

Reimplemented from MouseListener.

Reimplemented in Slider, TextEditor, CodeEditorComponent, and Label.

◆ mouseDown()

void ResizableWindow::mouseDrag ( const MouseEvent & )

overrideprotectedvirtualinherited

Reimplemented from Component.

◆ mouseEnter()

virtual void Component::mouseEnter ( const MouseEvent & event )

overridevirtualinherited

Called when the mouse first enters a component.

If the mouse button isn't pressed and the mouse moves into a component, this will be called to let the component react to this.

When the mouse button is pressed and held down while being moved in or out of a component, no mouseEnter or mouseExit callbacks are made - only mouseDrag messages are sent to the component that the mouse was originally clicked on, until the button is released.

Parameters

event details about the position and status of the mouse event, including the source component in which it occurred

See also: mouseExit, mouseDrag, mouseMove, contains

Reimplemented from MouseListener.

Reimplemented in Button, TableHeaderComponent, MidiKeyboardComponent, ResizableBorderComponent, TooltipWindow, and MenuBarComponent.

Referenced by MidiKeyboardComponent::getOctaveForMiddleC().

◆ mouseExit()

virtual void Component::mouseExit ( const MouseEvent & event )

overridevirtualinherited

Called when the mouse moves out of a component.

This will be called when the mouse moves off the edge of this component.

If the mouse button was pressed, and it was then dragged off the edge of the component and released, then this callback will happen when the button is released, after the mouseUp callback.

Parameters

event details about the position and status of the mouse event, including the source component in which it occurred

See also: mouseEnter, mouseDrag, mouseMove, contains

Reimplemented from MouseListener.

◆ mouseMagnify()

virtual void Component::mouseMagnify	(	const MouseEvent &	event,
		float	scaleFactor
	)

virtualinherited

Called when a pinch-to-zoom mouse-gesture is used.

If not overridden, a component will forward this message to its parent, so that parent components can collect gesture messages that are unused by child components.

Parameters

event	details about the mouse event
scaleFactor	a multiplier to indicate by how much the size of the target should be changed. A value of 1.0 would indicate no change, values greater than 1.0 mean it should be enlarged.

◆ mouseMove()

virtual void Component::mouseMove ( const MouseEvent & event )

overridevirtualinherited

Called when the mouse moves inside a component.

If the mouse button isn't pressed and the mouse moves over a component, this will be called to let the component react to this.

A component will always get a mouseEnter callback before a mouseMove.

Parameters

event details about the position and status of the mouse event, including the source component in which it occurred

Reimplemented from Component.

◆ mouseWheelMove()

virtual void Component::mouseWheelMove	(	const MouseEvent &	event,
		const MouseWheelDetails &	wheel
	)

overridevirtualinherited

Called when the mouse-wheel is moved.

This callback is sent to the component that the mouse is over when the wheel is moved.

If not overridden, a component will forward this message to its parent, so that parent components can collect mouse-wheel messages that happen to child components which aren't interested in them. (Bear in mind that if you attach a component as a mouse-listener to other components, then those wheel moves will also end up calling this method and being passed up to the parents, which may not be what you intended to happen).

Parameters

event	details about the mouse event
wheel	details about the mouse wheel movement

Reimplemented from MouseListener.

Reimplemented from Component.

◆ moveKeyboardFocusToSibling()

void Component::moveKeyboardFocusToSibling ( bool moveToNext )

inherited

Tries to move the keyboard focus to one of this component's siblings.

This will try to move focus to either the next or previous component. (This is the method that is used when shifting focus by pressing the tab key).

Components for which getWantsKeyboardFocus() returns false are not looked at.

Parameters

moveToNext if true, the focus will move forwards; if false, it will move backwards

◆ paint()

void ResizableWindow::paint ( Graphics & )

overrideprotectedvirtualinherited

Reimplemented from Component.

◆ paintEntireComponent()

void Component::paintEntireComponent	(	Graphics &	context,
		bool	ignoreAlphaLevel
	)

inherited

Draws this component and all its subcomponents onto the specified graphics context.

You should very rarely have to use this method, it's simply there in case you need to draw a component with a custom graphics context for some reason, e.g. for creating a snapshot of the component.

It calls paint(), paintOverChildren() and recursively calls paintEntireComponent() on its children in order to render the entire tree.

The graphics context may be left in an undefined state after this method returns, so you may need to reset it if you're going to use it again.

If ignoreAlphaLevel is false, then the component will be drawn with the opacity level specified by getAlpha(); if ignoreAlphaLevel is true, then this will be ignored and an alpha of 1.0 will be used.

◆ paintOverChildren()

virtual void Component::paintOverChildren ( Graphics & g )

virtualinherited

Components can override this method to draw over the top of their children.

For most drawing operations, it's better to use the normal paint() method, but if you need to overlay something on top of the children, this can be used.

◆ parentSizeChanged()

void ResizableWindow::parentSizeChanged ( )

overrideprotectedvirtualinherited

Reimplemented from Component.

◆ postCommandMessage()

void Component::postCommandMessage ( int commandId )

inherited

Dispatches a numbered message to this component.

This is a quick and cheap way of allowing simple asynchronous messages to be sent to components. It's also safe, because if the component that you send the message to is a null or dangling pointer, this won't cause an error.

The command ID is later delivered to the component's handleCommandMessage() method by the application's message queue.

See also: handleCommandMessage

◆ proportionOfHeight()

int Component::proportionOfHeight ( float proportion ) const

noexceptinherited

Returns a proportion of the component's height.

This is a handy equivalent of (getHeight() * proportion).

◆ proportionOfWidth()

int Component::proportionOfWidth ( float proportion ) const

noexceptinherited

Returns a proportion of the component's width.

This is a handy equivalent of (getWidth() * proportion).

◆ reallyContains()

bool Component::reallyContains	(	Point< int >	localPoint,
		bool	returnTrueIfWithinAChild
	)

inherited

Returns true if a given point lies in this component, taking any overlapping siblings into account.

Parameters

localPoint	the coordinate to test, relative to this component's top-left.
returnTrueIfWithinAChild	if the point actually lies within a child of this component, this determines whether that is counted as a hit.

◆ removeAllChildren()

void Component::removeAllChildren ( )

inherited

Removes all this component's children.

Note that this won't delete them! To do that, use deleteAllChildren() instead.

◆ removeChildComponent() [1/2]

void Component::removeChildComponent ( Component * childToRemove )

inherited

Removes one of this component's child-components.

If the child passed-in isn't actually a child of this component (either because it's invalid or is the child of a different parent), then no action is taken.

Note that removing a child will not delete it! But it's ok to delete a component without first removing it - doing so will automatically remove it and send out the appropriate notifications before the deletion completes.

See also: addChildComponent, ComponentListener::componentChildrenChanged

◆ removeChildComponent() [2/2]

Component* Component::removeChildComponent ( int childIndexToRemove )

inherited

Removes one of this component's child-components by index.

This will return a pointer to the component that was removed, or null if the index was out-of-range.

Note that removing a child will not delete it! But it's ok to delete a component without first removing it - doing so will automatically remove it and send out the appropriate notifications before the deletion completes.

See also: addChildComponent, ComponentListener::componentChildrenChanged

◆ removeColour()

void Component::removeColour ( int colourId )

inherited

If a colour has been set with setColour(), this will remove it.

This allows you to make a colour revert to its default state.

◆ removeComponentListener()

void Component::removeComponentListener ( ComponentListener * listenerToRemove )

inherited

Removes a component listener.

See also: addComponentListener

◆ removeFromDesktop()

void Component::removeFromDesktop ( )

inherited

If the component is currently showing on the desktop, this will hide it.

You can also use setVisible() to hide a desktop window temporarily, but removeFromDesktop() will free any system resources that are being used up.

See also: addToDesktop, isOnDesktop

◆ removeKeyListener()

void Component::removeKeyListener ( KeyListener * listenerToRemove )

inherited

Removes a previously-registered key listener.

See also: addKeyListener

◆ removeMouseListener()

void Component::removeMouseListener ( MouseListener * listenerToRemove )

inherited

Deregisters a mouse listener.

See also: addMouseListener, MouseListener

◆ repaint() [1/3]

void Component::repaint ( )

inherited

Marks the whole component as needing to be redrawn.

Calling this will not do any repainting immediately, but will mark the component as 'dirty'. At some point in the near future the operating system will send a paint message, which will redraw all the dirty regions of all components. There's no guarantee about how soon after calling repaint() the redraw will actually happen, and other queued events may be delivered before a redraw is done.

If the setBufferedToImage() method has been used to cause this component to use a buffer, the repaint() call will invalidate the cached buffer. If setCachedComponentImage() has been used to provide a custom image cache, that cache will be invalidated appropriately.

To redraw just a subsection of the component rather than the whole thing, use the repaint (int, int, int, int) method.

See also: paint

Referenced by OpenGLContext::NativeContext::NativeContext().

◆ repaint() [2/3]

void Component::repaint	(	int	x,
		int	y,
		int	width,
		int	height
	)

inherited

Marks a subsection of this component as needing to be redrawn.

Calling this will not do any repainting immediately, but will mark the given region of the component as 'dirty'. At some point in the near future the operating system will send a paint message, which will redraw all the dirty regions of all components. There's no guarantee about how soon after calling repaint() the redraw will actually happen, and other queued events may be delivered before a redraw is done.

The region that is passed in will be clipped to keep it within the bounds of this component.

See also: repaint()

◆ repaint() [3/3]

void Component::repaint ( Rectangle< int > area )

inherited

Marks a subsection of this component as needing to be redrawn.

Calling this will not do any repainting immediately, but will mark the given region of the component as 'dirty'. At some point in the near future the operating system will send a paint message, which will redraw all the dirty regions of all components. There's no guarantee about how soon after calling repaint() the redraw will actually happen, and other queued events may be delivered before a redraw is done.

The region that is passed in will be clipped to keep it within the bounds of this component.

◆ resized()

void DialogWindow::resized ( )

overrideprotectedvirtual

Reimplemented from Component.

◆ restoreWindowStateFromString()

bool ResizableWindow::restoreWindowStateFromString ( const String & previousState )

inherited

Restores the window to a previously-saved size and position.

This restores the window's size, position and full-screen status from an string that was previously created with the getWindowStateAsString() method.

Returns: false if the string wasn't a valid window state

See also: getWindowStateAsString

◆ runModalLoop()

int Component::runModalLoop ( )

inherited

Runs a component modally, waiting until the loop terminates.

This method first makes the component visible, brings it to the front and gives it the keyboard focus.

It then runs a loop, dispatching messages from the system message queue, but blocking all mouse or keyboard messages from reaching any components other than this one and its children.

This loop continues until the component's exitModalState() method is called (or the component is deleted), and then this method returns, returning the value passed into exitModalState().

Note that you SHOULD NEVER USE THIS METHOD! Modal loops are a dangerous construct because things that happen during the events that they dispatch could affect the state of objects which are currently in use somewhere on the stack, so when the loop finishes and the stack unwinds, horrible problems can occur. This is especially bad in plugins, where the host may choose to delete the plugin during runModalLoop(), so that when it returns, the entire DLL could have been unloaded from memory! Also, some OSes deliberately make it impossible to run modal loops (e.g. Android), so this method won't even exist on some platforms.

See also: enterModalState, exitModalState, isCurrentlyModal, getCurrentlyModalComponent, isCurrentlyBlockedByAnotherModalComponent, ModalComponentManager

◆ sendLookAndFeelChange()

void Component::sendLookAndFeelChange ( )

inherited

Calls the lookAndFeelChanged() method in this component and all its children.

This will recurse through the children and their children, calling lookAndFeelChanged() on them all.

See also: lookAndFeelChanged

◆ setAlpha()

void Component::setAlpha ( float newAlpha )

inherited

Changes the transparency of this component.

When painted, the entire component and all its children will be rendered with this as the overall opacity level, where 0 is completely invisible, and 1.0 is fully opaque (i.e. normal).

See also: getAlpha, alphaChanged

◆ setAlwaysOnTop()

void Component::setAlwaysOnTop ( bool shouldStayOnTop )

inherited

Sets whether the component should always be kept at the front of its siblings.

See also: isAlwaysOnTop

◆ setBackgroundColour()

void ResizableWindow::setBackgroundColour ( Colour newColour )

inherited

Changes the colour currently being used for the window's background.

As a convenience the window will fill itself with this colour, but you can override the paint() method if you need more customised behaviour.

Note that the opaque state of this window is altered by this call to reflect the opacity of the colour passed-in. On window systems which can't support semi-transparent windows this might cause problems, (though it's unlikely you'll be using this class as a base for a semi-transparent component anyway).

You can also use the ResizableWindow::backgroundColourId colour id to set this colour.

See also: getBackgroundColour

◆ setBounds() [1/4]

void Component::setBounds	(	int	x,
		int	y,
		int	width,
		int	height
	)

inherited

Changes the component's position and size.

The coordinates are relative to the top-left of the component's parent, or relative to the origin of the screen if the component is on the desktop.

If this method changes the component's top-left position, it will make a synchronous call to moved(). If it changes the size, it will also make a call to resized().

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to whatever bounds you set for it.

See also: setTopLeftPosition, setSize, ComponentListener::componentMovedOrResized

◆ setBounds() [2/4]

void Component::setBounds ( Rectangle< int > newBounds )

inherited

Changes the component's position and size.

The coordinates are relative to the top-left of the component's parent, or relative to the origin of the screen if the component is on the desktop.

If this method changes the component's top-left position, it will make a synchronous call to moved(). If it changes the size, it will also make a call to resized().

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to whatever bounds you set for it.

◆ setBounds() [4/4]

void Component::setBounds ( const String & )

◆ setBoundsConstrained()

void ResizableWindow::setBoundsConstrained ( const Rectangle< int > & newBounds )

inherited

Calls the window's setBounds method, after first checking these bounds with the current constrainer.

See also: setConstrainer

◆ setBoundsInset()

void Component::setBoundsInset ( BorderSize< int > borders )

inherited

Changes the component's position and size based on the amount of space to leave around it.

This will position the component within its parent, leaving the specified number of pixels around each edge.

See also: setBounds

◆ setBoundsRelative()

void Component::setBoundsRelative	(	float	proportionalX,
		float	proportionalY,
		float	proportionalWidth,
		float	proportionalHeight
	)

inherited

Changes the component's position and size in terms of fractions of its parent's size.

The values are factors of the parent's size, so for example setBoundsRelative (0.2f, 0.2f, 0.5f, 0.5f) would give it half the width and height of the parent, with its top-left position 20% of the way across and down the parent.

See also: setBounds

◆ setBoundsToFit()

void Component::setBoundsToFit	(	int	x,
		int	y,
		int	width,
		int	height,
		Justification	justification,
		bool	onlyReduceInSize
	)

inherited

Positions the component within a given rectangle, keeping its proportions unchanged.

If onlyReduceInSize is false, the component will be resized to fill as much of the rectangle as possible without changing its aspect ratio (the component's current size is used to determine its aspect ratio, so a zero-size component won't work here). If onlyReduceInSize is true, it will only be resized if it's too big to fit inside the rectangle.

It will then be positioned within the rectangle according to the justification flags specified.

See also: setBounds

◆ setBroughtToFrontOnMouseClick()

void Component::setBroughtToFrontOnMouseClick ( bool shouldBeBroughtToFront )

noexceptinherited

Indicates whether the component should be brought to the front when clicked.

Setting this flag to true will cause the component to be brought to the front when the mouse is clicked somewhere inside it or its child components.

Note that a top-level desktop window might still be brought to the front by the operating system when it's clicked, depending on how the OS works.

By default this is set to false.

See also: setMouseClickGrabsKeyboardFocus

◆ setBufferedToImage()

void Component::setBufferedToImage ( bool shouldBeBuffered )

inherited

Makes the component use an internal buffer to optimise its redrawing.

Setting this flag to true will cause the component to allocate an internal buffer into which it paints itself and all its child components, so that when asked to redraw itself, it can use this buffer rather than actually calling the paint() method.

Parts of the buffer are invalidated when repaint() is called on this component or its children. The buffer is then repainted at the next paint() callback.

See also: repaint, paint, createComponentSnapshot

◆ setCachedComponentImage()

void Component::setCachedComponentImage ( CachedComponentImage * newCachedImage )

inherited

Gives the component a CachedComponentImage that should be used to buffer its painting.

The object that is passed-in will be owned by this component, and will be deleted automatically later on.

See also: setBufferedToImage

◆ setCentrePosition() [1/2]

void Component::setCentrePosition	(	int	x,
		int	y
	)

inherited

Changes the position of the component's centre.

Leaves the component's size unchanged, but sets the position of its centre relative to its parent's top-left.

See also: setBounds

◆ setCentrePosition() [2/2]

void Component::setCentrePosition ( Point< int > newCentrePosition )

inherited

Changes the position of the component's centre.

Leaves the component's size unchanged, but sets the position of its centre relative to its parent's top-left.

See also: setBounds

◆ setCentreRelative()

void Component::setCentreRelative	(	float	x,
		float	y
	)

inherited

Changes the position of the component's centre.

Leaves the size unchanged, but positions its centre relative to its parent's size. E.g. setCentreRelative (0.5f, 0.5f) would place it centrally in its parent.

◆ setColour()

void Component::setColour	(	int	colourId,
		Colour	newColour
	)

inherited

Registers a colour to be used for a particular purpose.

Changing a colour will cause a synchronous callback to the colourChanged() method, which your component can override if it needs to do something when colours are altered.

For more details about colour IDs, see the comments for findColour().

See also: findColour, isColourSpecified, colourChanged, LookAndFeel::findColour, LookAndFeel::setColour

Referenced by DrawableText::getText().

◆ setComponentEffect()

void Component::setComponentEffect ( ImageEffectFilter * newEffect )

inherited

Adds an effect filter to alter the component's appearance.

When a component has an effect filter set, then this is applied to the results of its paint() method. There are a few preset effects, such as a drop-shadow or glow, but they can be user-defined as well.

The effect that is passed in will not be deleted by the component - the caller must take care of deleting it.

To remove an effect from a component, pass a null pointer in as the parameter.

See also: ImageEffectFilter, DropShadowEffect, GlowEffect

◆ setComponentID()

void Component::setComponentID ( const String & newID )

inherited

Sets the component's ID string.

You can retrieve the ID using getComponentID().

See also: getComponentID, findChildWithID

◆ setConstrainer()

void ResizableWindow::setConstrainer ( ComponentBoundsConstrainer * newConstrainer )

inherited

Sets the bounds-constrainer object to use for resizing and dragging this window.

A pointer to the object you pass in will be kept, but it won't be deleted by this object, so it's the caller's responsibility to manage it.

If you pass a nullptr, then no contraints will be placed on the positioning of the window.

◆ setContentComponent()

void ResizableWindow::setContentComponent	(	Component *	newContentComponent,
		bool	deleteOldOne = `true`,
		bool	resizeToFit = `false`
	)

inherited

deprecated

◆ setContentComponentSize()

void ResizableWindow::setContentComponentSize	(	int	width,
		int	height
	)

inherited

Changes the window so that the content component ends up with the specified size.

This is basically a setSize call on the window, but which adds on the borders, so you can specify the content component's target size.

◆ setContentNonOwned()

void ResizableWindow::setContentNonOwned	(	Component *	newContentComponent,
		bool	resizeToFitWhenContentChangesSize
	)

inherited

Changes the current content component.

This sets a component that will be placed in the centre of the ResizableWindow, (leaving a space around the edge for the border).

You should never add components directly to a ResizableWindow (or any of its subclasses) with addChildComponent(). Instead, add them to the content component.

Parameters

newContentComponent	the new component to use - this component will NOT be deleted by this component, so it's the caller's responsibility to manage its lifetime (it's ok to delete it while this window is still using it). To set a content component that the window will delete, call setContentOwned() instead.
resizeToFitWhenContentChangesSize	if true, then the ResizableWindow will maintain its size such that it always fits around the size of the content component. If false, the new content will be resized to fit the current space available.

◆ setContentOwned()

void ResizableWindow::setContentOwned	(	Component *	newContentComponent,
		bool	resizeToFitWhenContentChangesSize
	)

inherited

Changes the current content component.

This sets a component that will be placed in the centre of the ResizableWindow, (leaving a space around the edge for the border).

You should never add components directly to a ResizableWindow (or any of its subclasses) with addChildComponent(). Instead, add them to the content component.

Parameters

newContentComponent	the new component to use - this component will be deleted when it's no longer needed (i.e. when the window is deleted or a new content component is set for it). To set a component that this window will not delete, call setContentNonOwned() instead.
resizeToFitWhenContentChangesSize	if true, then the ResizableWindow will maintain its size such that it always fits around the size of the content component. If false, the new content will be resized to fit the current space available.

◆ setDraggable()

void ResizableWindow::setDraggable ( bool shouldBeDraggable )

noexceptinherited

Can be used to enable or disable user-dragging of the window.

◆ setDropShadowEnabled()

void TopLevelWindow::setDropShadowEnabled ( bool useShadow )

inherited

Turns the drop-shadow on and off.

◆ setEnabled()

void Component::setEnabled ( bool shouldBeEnabled )

inherited

Enables or disables this component.

Disabling a component will also cause all of its child components to become disabled.

Similarly, enabling a component which is inside a disabled parent component won't make any difference until the parent is re-enabled.

See also: isEnabled, enablementChanged

◆ setExplicitFocusOrder()

void Component::setExplicitFocusOrder ( int newFocusOrderIndex )

inherited

Sets the index used in determining the order in which focusable components should be traversed.

A value of 0 or less is taken to mean that no explicit order is wanted, and that traversal should use other factors, like the component's position.

See also: getExplicitFocusOrder, moveKeyboardFocusToSibling

◆ setFocusContainer()

void Component::setFocusContainer ( bool shouldBeFocusContainer )

noexceptinherited

Indicates whether this component is a parent for components that can have their focus traversed.

This flag is used by the default implementation of the createFocusTraverser() method, which uses the flag to find the first parent component (of the currently focused one) which wants to be a focus container.

So using this method to set the flag to 'true' causes this component to act as the top level within which focus is passed around.

See also: isFocusContainer, createFocusTraverser, moveKeyboardFocusToSibling

◆ setFullScreen()

void ResizableWindow::setFullScreen ( bool shouldBeFullScreen )

inherited

Puts the window into full-screen mode, or restores it to its normal size.

If true, the window will become full-screen; if false, it will return to the last size it was before being made full-screen.

See also: isFullScreen

◆ setIcon()

void DocumentWindow::setIcon ( const Image & imageToUse )

inherited

Sets an icon to show in the title bar, next to the title.

A copy is made internally of the image, so the caller can delete the image after calling this. If 0 is passed-in, any existing icon will be removed.

◆ setInterceptsMouseClicks()

void Component::setInterceptsMouseClicks	(	bool	allowClicksOnThisComponent,
		bool	allowClicksOnChildComponents
	)

noexceptinherited

Changes the default return value for the hitTest() method.

Setting this to false is an easy way to make a component pass its mouse-clicks through to the components behind it.

When a component is created, the default setting for this is true.

Parameters

allowClicksOnThisComponent	if true, hitTest() will always return true; if false, it will return false (or true for child components if allowClicksOnChildComponents is true)
allowClicksOnChildComponents	if this is true and allowClicksOnThisComponent is false, then child components can be clicked on as normal but clicks on this component pass straight through; if this is false and allowClicksOnThisComponent is false, then neither this component nor any child components can be clicked on

See also: hitTest, getInterceptsMouseClicks

◆ setLookAndFeel()

void Component::setLookAndFeel ( LookAndFeel * newLookAndFeel )

inherited

Sets the look and feel to use for this component.

This will also change the look and feel for any child components that haven't had their look set explicitly.

The object passed in will not be deleted by the component, so it's the caller's responsibility to manage it. It may be used at any time until this component has been deleted.

Calling this method will also invoke the sendLookAndFeelChange() method.

See also: getLookAndFeel, lookAndFeelChanged

◆ setMenuBar()

void DocumentWindow::setMenuBar	(	MenuBarModel *	menuBarModel,
		int	menuBarHeight = `0`
	)

inherited

Creates a menu inside this window.

Parameters

menuBarModel	this specifies a MenuBarModel that should be used to generate the contents of a menu bar that will be placed just below the title bar, and just above any content component. If this value is a nullptr, any existing menu bar will be removed from the component; if it is not a nullptr, one will be added if it's required.
menuBarHeight	the height of the menu bar component, if one is needed. Pass a value of zero or less to use the look-and-feel's default size.

◆ setMenuBarComponent()

void DocumentWindow::setMenuBarComponent ( Component * newMenuBarComponent )

inherited

Replaces the current menu bar with a custom component.

The component will be owned and deleted by the document window.

◆ setMinimised()

void ResizableWindow::setMinimised ( bool shouldMinimise )

inherited

Minimises the window, or restores it to its previous position and size.

When being un-minimised, it'll return to the last position and size it was in before being minimised.

See also: isMinimised

◆ setMouseClickGrabsKeyboardFocus()

void Component::setMouseClickGrabsKeyboardFocus ( bool shouldGrabFocus )

inherited

Chooses whether a click on this component automatically grabs the focus.

By default this is set to true, but you might want a component which can be focused, but where you don't want the user to be able to affect it directly by clicking.

◆ setMouseCursor()

void Component::setMouseCursor ( const MouseCursor & cursorType )

inherited

Changes the mouse cursor shape to use when the mouse is over this component.

Note that the cursor set by this method can be overridden by the getMouseCursor method.

See also: MouseCursor

◆ setName()

void DocumentWindow::setName ( const String & newName )

overridevirtualinherited

Changes the component's name.

(This is overridden from Component::setName() to cause a repaint, as the name is what gets drawn across the window's title bar).

Reimplemented from Component.

◆ setOpaque()

void Component::setOpaque ( bool shouldBeOpaque )

inherited

Indicates whether any parts of the component might be transparent.

Components that always paint all of their contents with solid colour and thus completely cover any components behind them should use this method to tell the repaint system that they are opaque.

This information is used to optimise drawing, because it means that objects underneath opaque windows don't need to be painted.

By default, components are considered transparent, unless this is used to make it otherwise.

See also: isOpaque

◆ setPaintingIsUnclipped()

void Component::setPaintingIsUnclipped ( bool shouldPaintWithoutClipping )

noexceptinherited

This allows you to indicate that this component doesn't require its graphics context to be clipped when it is being painted.

Most people will never need to use this setting, but in situations where you have a very large number of simple components being rendered, and where they are guaranteed never to do any drawing beyond their own boundaries, setting this to true will reduce the overhead involved in clipping the graphics context that gets passed to the component's paint() callback. If you enable this mode, you'll need to make sure your paint method doesn't call anything like Graphics::fillAll(), and doesn't draw beyond the component's bounds, because that'll produce artifacts. Your component also can't have any child components that may be placed beyond its bounds.

◆ setPositioner()

void Component::setPositioner ( Positioner * newPositioner )

inherited

Sets a new Positioner object for this component.

If there's currently another positioner set, it will be deleted. The object that is passed in will be deleted automatically by this component when it's no longer required. Pass a null pointer to clear the current positioner.

See also: getPositioner()

◆ setRepaintsOnMouseActivity()

void Component::setRepaintsOnMouseActivity ( bool shouldRepaint )

noexceptinherited

Causes automatic repaints when the mouse enters or exits this component.

If turned on, then when the mouse enters/exits, or when the button is pressed/released on the component, it will trigger a repaint.

This is handy for things like buttons that need to draw themselves differently when the mouse moves over them, and it avoids having to override all the different mouse callbacks and call repaint().

See also: mouseEnter, mouseExit, mouseDown, mouseUp

◆ setResizable()

void ResizableWindow::setResizable	(	bool	shouldBeResizable,
		bool	useBottomRightCornerResizer
	)

inherited

Make the window resizable or fixed.

Parameters

shouldBeResizable	whether it's resizable at all
useBottomRightCornerResizer	if true, it'll add a ResizableCornerComponent at the bottom-right; if false, it'll use a ResizableBorderComponent around the edge

See also: setResizeLimits, isResizable

◆ setResizeLimits()

void ResizableWindow::setResizeLimits	(	int	newMinimumWidth,
		int	newMinimumHeight,
		int	newMaximumWidth,
		int	newMaximumHeight
	)

noexceptinherited

This sets the maximum and minimum sizes for the window.

If the window's current size is outside these limits, it will be resized to make sure it's within them.

A direct call to setBounds() will bypass any constraint checks, but when the window is dragged by the user or resized by other indirect means, the constrainer will limit the numbers involved.

See also: setResizable, setFixedAspectRatio

◆ setSize()

void Component::setSize	(	int	newWidth,
		int	newHeight
	)

inherited

Changes the size of the component.

A synchronous call to resized() will occur if the size actually changes.

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to whatever bounds you set for it.

Referenced by CarbonViewWrapperComponent::setOurSizeToEmbeddedViewSize(), and StandalonePluginHolder::showAudioSettingsDialog().

◆ setTitleBarButtonsRequired()

void DocumentWindow::setTitleBarButtonsRequired	(	int	requiredButtons,
		bool	positionTitleBarButtonsOnLeft
	)

inherited

Changes the set of title-bar buttons being shown.

Parameters

requiredButtons	specifies which of the buttons (close, minimise, maximise) should be shown on the title bar. This value is a bitwise combination of values from the TitleBarButtons enum. Note that it can be "allButtons" to get them all.
positionTitleBarButtonsOnLeft	if true, the buttons should go at the left side of the bar; if false, they'll be placed at the right

◆ setTitleBarHeight()

void DocumentWindow::setTitleBarHeight ( int newHeight )

inherited

Changes the height of the title-bar.

◆ setTitleBarTextCentred()

void DocumentWindow::setTitleBarTextCentred ( bool textShouldBeCentred )

inherited

Sets whether the title should be centred within the window.

If true, the title text is shown in the middle of the title-bar; if false, it'll be shown at the left of the bar.

◆ setTopLeftPosition() [1/2]

void Component::setTopLeftPosition	(	int	x,
		int	y
	)

inherited

Moves the component to a new position.

Changes the component's top-left position (without changing its size). The position is relative to the top-left of the component's parent.

If the component actually moves, this method will make a synchronous call to moved().

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to whatever bounds you set for it.

See also: setBounds, ComponentListener::componentMovedOrResized

◆ setTopLeftPosition() [2/2]

void Component::setTopLeftPosition ( Point< int > newTopLeftPosition )

inherited

Moves the component to a new position.

Changes the component's top-left position (without changing its size). The position is relative to the top-left of the component's parent.

If the component actually moves, this method will make a synchronous call to moved().

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to whatever bounds you set for it.

See also: setBounds, ComponentListener::componentMovedOrResized

◆ setTopRightPosition()

void Component::setTopRightPosition	(	int	x,
		int	y
	)

inherited

Moves the component to a new position.

Changes the position of the component's top-right corner (keeping it the same size). The position is relative to the top-left of the component's parent.

If the component actually moves, this method will make a synchronous call to moved().

Note that if you've used setTransform() to apply a transform, then the component's bounds will no longer be a direct reflection of the position at which it appears within its parent, as the transform will be applied to whatever bounds you set for it.

◆ setTransform()

void Component::setTransform ( const AffineTransform & transform )

inherited

Sets a transform matrix to be applied to this component.

If you set a transform for a component, the component's position will be warped by it, relative to the component's parent's top-left origin. This means that the values you pass into setBounds() will no longer reflect the actual area within the parent that the component covers, as the bounds will be transformed and the component will probably end up actually appearing somewhere else within its parent.

When using transforms you need to be extremely careful when converting coordinates between the coordinate spaces of different components or the screen - you should always use getLocalPoint(), getLocalArea(), etc to do this, and never just manually add a component's position to a point in order to convert it between different components (but I'm sure you would never have done that anyway...).

Currently, transforms are not supported for desktop windows, so the transform will be ignored if you put a component on the desktop.

To remove a component's transform, simply pass AffineTransform() as the parameter to this method.

◆ setUsingNativeTitleBar()

void TopLevelWindow::setUsingNativeTitleBar ( bool useNativeTitleBar )

inherited

Sets whether an OS-native title bar will be used, or a Juce one.

See also: isUsingNativeTitleBar

◆ setViewportIgnoreDragFlag()

void Component::setViewportIgnoreDragFlag ( bool ignoreDrag )

inlinenoexceptinherited

Sets a flag to indicate whether mouse drag events on this Component should be ignored when it is inside a Viewport with drag-to-scroll functionality enabled.

This is useful for Components such as sliders that should not move their parent Viewport when dragged.

◆ setVisible()

virtual void Component::setVisible ( bool shouldBeVisible )

virtualinherited

Makes the component visible or invisible.

This method will show or hide the component. Note that components default to being non-visible when first created. Also note that visible components won't be seen unless all their parent components are also visible.

This method will call visibilityChanged() and also componentVisibilityChanged() for any component listeners that are interested in this component.

Parameters

shouldBeVisible whether to show or hide the component

See also: isVisible, isShowing, visibilityChanged, ComponentListener::componentVisibilityChanged

Referenced by VideoComponent::Pimpl::Pimpl().

◆ setWantsKeyboardFocus()

void Component::setWantsKeyboardFocus ( bool wantsFocus )

noexceptinherited

Sets a flag to indicate whether this component needs keyboard focus or not.

By default components aren't actually interested in gaining the focus, but this method can be used to turn this on.

See the grabKeyboardFocus() method for details about the way a component is chosen to receive the focus.

◆ showDialog()

static void DialogWindow::showDialog	(	const String &	dialogTitle,
		Component *	contentComponent,
		Component *	componentToCentreAround,
		Colour	backgroundColour,
		bool	escapeKeyTriggersCloseButton,
		bool	shouldBeResizable = `false`,
		bool	useBottomRightCornerResizer = `false`
	)

static

Easy way of quickly showing a dialog box containing a given component.

Note: this method has been superceded by the DialogWindow::LaunchOptions structure, which does the same job with some extra flexibility. The showDialog method is here for backwards compatibility, but please use DialogWindow::LaunchOptions in new code.

This will open and display a DialogWindow containing a given component, making it modal, but returning immediately to allow the dialog to finish in its own time. If you want to block and run a modal loop until the dialog is dismissed, use showModalDialog() instead.

To close the dialog programmatically, you should call exitModalState (returnValue) on the DialogWindow that is created. To find a pointer to this window from your contentComponent, you can do something like this:

if (DialogWindow* dw = contentComponent->findParentComponentOfClass<DialogWindow>())

dw->exitModalState (1234);

Parameters

dialogTitle	the dialog box's title
contentComponent	the content component for the dialog box. Make sure that this has been set to the size you want it to be before calling this method. The component won't be deleted by this call, so you can re-use it or delete it afterwards
componentToCentreAround	if this is not a nullptr, it indicates a component that you'd like to show this dialog box in front of. See the DocumentWindow::centreAroundComponent() method for more info on this parameter
backgroundColour	a colour to use for the dialog box's background colour
escapeKeyTriggersCloseButton	if true, then pressing the escape key will cause the close button to be triggered
shouldBeResizable	if true, the dialog window has either a resizable border, or a corner resizer
useBottomRightCornerResizer	if shouldBeResizable is true, this indicates whether to use a border or corner resizer component. See ResizableWindow::setResizable()

◆ showModalDialog()

static int DialogWindow::showModalDialog	(	const String &	dialogTitle,
		Component *	contentComponent,
		Component *	componentToCentreAround,
		Colour	backgroundColour,
		bool	escapeKeyTriggersCloseButton,
		bool	shouldBeResizable = `false`,
		bool	useBottomRightCornerResizer = `false`
	)

static

Easy way of quickly showing a dialog box containing a given component.

Note: this method has been superceded by the DialogWindow::LaunchOptions structure, which does the same job with some extra flexibility. The showDialog method is here for backwards compatibility, but please use DialogWindow::LaunchOptions in new code.

This will open and display a DialogWindow containing a given component, returning when the user clicks its close button.

It returns the value that was returned by the dialog box's runModalLoop() call.

To close the dialog programmatically, you should call exitModalState (returnValue) on the DialogWindow that is created. To find a pointer to this window from your contentComponent, you can do something like this:

if (DialogWindow* dw = contentComponent->findParentComponentOfClass<DialogWindow>())

dw->exitModalState (1234);

Parameters

dialogTitle	the dialog box's title
contentComponent	the content component for the dialog box. Make sure that this has been set to the size you want it to be before calling this method. The component won't be deleted by this call, so you can re-use it or delete it afterwards
componentToCentreAround	if this is not a nullptr, it indicates a component that you'd like to show this dialog box in front of. See the DocumentWindow::centreAroundComponent() method for more info on this parameter
backgroundColour	a colour to use for the dialog box's background colour
escapeKeyTriggersCloseButton	if true, then pressing the escape key will cause the close button to be triggered
shouldBeResizable	if true, the dialog window has either a resizable border, or a corner resizer
useBottomRightCornerResizer	if shouldBeResizable is true, this indicates whether to use a border or corner resizer component. See ResizableWindow::setResizable()

◆ toBack()

void Component::toBack ( )

inherited

Changes this component's z-order to be at the back of all its siblings.

If the component is set to be 'always-on-top', it will only be moved to the back of the other other 'always-on-top' components.

See also: toFront, toBehind, setAlwaysOnTop

◆ toBehind()

void Component::toBehind ( Component * other )

inherited

Changes this component's z-order so that it's just behind another component.

See also: toFront, toBack

◆ toFront()

void Component::toFront ( bool shouldAlsoGainFocus )

inherited

Brings the component to the front of its siblings.

If some of the component's siblings have had their 'always-on-top' flag set, then they will still be kept in front of this one (unless of course this one is also 'always-on-top').

Parameters

shouldAlsoGainFocus if true, this will also try to assign keyboard focus to the component (see grabKeyboardFocus() for more details)

See also: toBack, toBehind, setAlwaysOnTop

◆ unfocusAllComponents()

static void Component::unfocusAllComponents ( )

staticinherited

If any component has keyboard focus, this will defocus it.

◆ updateMouseCursor()

void Component::updateMouseCursor ( ) const

inherited

Forces the current mouse cursor to be updated.

If you're overriding the getMouseCursor() method to control which cursor is displayed, then this will only be checked each time the user moves the mouse. So if you want to force the system to check that the cursor being displayed is up-to-date (even if the mouse is just sitting there), call this method.

(If you're changing the cursor using setMouseCursor(), you don't need to bother calling this).

◆ userTriedToCloseWindow()

virtual void Component::userTriedToCloseWindow ( )

virtualinherited

For components on the desktop, this is called if the system wants to close the window.

This is a signal that either the user or the system wants the window to close. The default implementation of this method will trigger an assertion to warn you that your component should do something about it, but you can override this to ignore the event if you want.

Reimplemented in AlertWindow.

◆ visibilityChanged()

void ResizableWindow::visibilityChanged ( )

overrideprotectedvirtualinherited

Reimplemented from Component.
