Detailed Description

Represents a mouse cursor image.

This object can either be used to represent one of the standard mouse cursor shapes, or a custom one generated from an image.

Constructor & Destructor Documentation

MouseCursor() [1/6]

MouseCursor::MouseCursor ( )

noexcept

Creates the standard arrow cursor.

MouseCursor() [2/6]

MouseCursor::MouseCursor

(

StandardCursorType

)

Creates one of the standard mouse cursor.

MouseCursor() [3/6]

MouseCursor::MouseCursor	(	const Image &	image,
		int	hotSpotX,
		int	hotSpotY
	)

Creates a custom cursor from an image.

Parameters

image	the image to use for the cursor - if this is bigger than the system can manage, it might get scaled down first, and might also have to be turned to black-and-white if it can't do colour cursors.
hotSpotX	the x position of the cursor's hotspot within the image
hotSpotY	the y position of the cursor's hotspot within the image

MouseCursor() [4/6]

MouseCursor::MouseCursor	(	const Image &	image,
		int	hotSpotX,
		int	hotSpotY,
		float	scaleFactor
	)

Creates a custom cursor from an image.

Parameters

image	the image to use for the cursor - if this is bigger than the system can manage, it might get scaled down first, and might also have to be turned to black-and-white if it can't do colour cursors.
hotSpotX	the x position of the cursor's hotspot within the image
hotSpotY	the y position of the cursor's hotspot within the image
scaleFactor	the factor by which this image is larger than the target screen size of the cursor.

MouseCursor() [5/6]

MouseCursor::MouseCursor

(

const MouseCursor &

)

Creates a copy of another cursor object.

~MouseCursor()

MouseCursor::~MouseCursor

(

)

Destructor.

MouseCursor() [6/6]

MouseCursor::MouseCursor ( MouseCursor &&  )

noexcept

Move constructor.

If showWaitCursor has been called, this will return the mouse to its normal state.

This will look at what component is under the mouse, and update the cursor to be the correct one for that component.

showWaitCursor

operator!=() [1/2]

bool MouseCursor::operator!= ( const MouseCursor &  ) const

noexcept

Checks whether two mouse cursors are the same.

For custom cursors, two cursors created from the same image won't be recognised as the same, only MouseCursor objects that have been copied from the same object.

operator!=() [2/2]

bool MouseCursor::operator!= ( StandardCursorType  type ) const

noexcept

Checks whether this cursor is of the standard type mentioned.

operator=() [1/2]

MouseCursor& MouseCursor::operator=

(

const MouseCursor &

)

Copies this cursor from another object.

operator=() [2/2]

MouseCursor& MouseCursor::operator= ( MouseCursor &&  )

noexcept

Move assignment operator.

operator==() [1/2]

bool MouseCursor::operator== ( const MouseCursor &  ) const

noexcept

Checks whether two mouse cursors are the same.

For custom cursors, two cursors created from the same image won't be recognised as the same, only MouseCursor objects that have been copied from the same object.

operator==() [2/2]

bool MouseCursor::operator== ( StandardCursorType  type ) const

noexcept

Checks whether this cursor is of the standard type mentioned.

showInAllWindows()

void MouseCursor::showInAllWindows ( ) const

private

showInWindow()

void MouseCursor::showInWindow ( ComponentPeer *  window ) const

private

showWaitCursor()

static void MouseCursor::showWaitCursor ( )

static

Makes the system show its default 'busy' cursor.

This will turn the system cursor to an hourglass or spinning beachball until the next time the mouse is moved, or hideWaitCursor() is called.

This is handy if the message loop is about to block for a couple of seconds while busy and you want to give the user feedback about this.
