Detailed Description

This class defines a collection of settings to be used to open a DialogWindow.

The easiest way to open a DialogWindow is to create yourself a LaunchOptions structure, initialise its fields with the appropriate details, and then call its launchAsync() method to launch the dialog.

Constructor & Destructor Documentation

◆ LaunchOptions()

juce::DialogWindow::LaunchOptions::LaunchOptions ( )

noexcept

Member Function Documentation

◆ create()

DialogWindow* juce::DialogWindow::LaunchOptions::create ( )

Creates a new DialogWindow instance with these settings.

This method simply creates the window, it doesn't run it modally. In most cases you'll want to use launchAsync() or runModal() instead.

◆ launchAsync()

DialogWindow* juce::DialogWindow::LaunchOptions::launchAsync ( )

Launches a new modal dialog window.

This will create a dialog based on the settings in this structure, launch it modally, and return immediately. The window that is returned will be automatically deleted when the modal state is terminated.

When the dialog's close button is clicked, it'll automatically terminate its modal state, but you can also do this programmatically by calling exitModalState (returnValue) on the DialogWindow.

If your content component needs to find the dialog window that it is contained in, a quick trick is to do this:

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

dw->exitModalState (1234);

◆ runModal()

int juce::DialogWindow::LaunchOptions::runModal ( )

Launches and runs the dialog modally, returning the status code that was used to terminate the modal loop.

Note that running modal loops inline is a BAD technique. If possible, always use launchAsync() instead of this method.

Member Data Documentation

◆ componentToCentreAround

Component* juce::DialogWindow::LaunchOptions::componentToCentreAround = nullptr

If this is not a nullptr, it indicates a component that you'd like to position this dialog box in front of.

See the DocumentWindow::centreAroundComponent() method for more info about this parameter.

◆ content

OptionalScopedPointer<Component> juce::DialogWindow::LaunchOptions::content

The content component to show in the window.

This must not be null! Using an OptionalScopedPointer to hold this pointer lets you indicate whether you'd like the dialog to automatically delete the component when the dialog has terminated.
