Public Member Functions
	Platform ()

	~Platform () override

Core::ViewFactory *	createDefaultViewFactory () override
	Creates and returns the default ViewFactory.

Core::View *	createView (Core::Controller controller, Core::View parent=nullptr) const override
	Create an empty view For Qt this would just returns a empty QWidget or QQuickItem other frontends can return something as basic.

bool	inDisallowedDragView (QPoint globalPos) const override

const char *	name () const override
	Returns the name of the platform, only "qtwidgets" and "qtquick".

QQmlEngine *	qmlEngine () const

std::shared_ptr< Core::View >	qobjectAsView (QObject *) const override
	Returns the specified QObject casted to View Nullptr if it's not a view.

int	screenNumberForView (Core::View *) const override
	Returns the screen index for the specified view or window. It's up to the platform to decide how screens are ordered, kddw won't care.

QSize	screenSizeFor (Core::View *) const override
	Returns the size of the screen where this view is in.

void	setQmlEngine (QQmlEngine *)

void	ungrabMouse () override
	Releases the mouse grab, if any.

bool	usesFallbackMouseGrabber () const override
	Return whether we use the global event filter based mouse grabber.

QtQuick::ViewFactory *	viewFactory () const

std::shared_ptr< Core::Window >	windowAt (QPoint globalPos) const override

std::shared_ptr< Core::Window >	windowFromQWindow (QWindow *) const override

Public Member Functions inherited from KDDockWidgets::QtCommon::Platform_qt
	Platform_qt ()

	~Platform_qt () override

QString	applicationName () const override
	Returns the application name This name will be used as title of floating dock widgets which contain more than 1 group.

QPoint	cursorPos () const override
	Returns the mouse cursor position in screen coordinates.

DisplayType	displayType () const override
	Returns the type of graphics stack being used.

std::shared_ptr< Core::View >	focusedView () const override
	Returns the focused view, if any.

bool	isLeftMouseButtonPressed () const override
	Returns whether the left mouse button is pressed.

bool	isProcessingAppQuitEvent () const override
	Returns whether we're processing a Event::Quit.

std::shared_ptr< Core::Screen >	primaryScreen () const override

std::shared_ptr< Core::Window >	qobjectAsWindow (QObject *) const

QByteArray	readFile (const QString &fileName, bool &ok) const override

void	restoreMouseCursor () override
	Undoes the call to setMouseCursor()

void	runDelayed (int ms, Core::DelayedCall *) override

int	screenNumberForWindow (std::shared_ptr< Core::Window >) const override

QVector< std::shared_ptr< Core::Screen > >	screens () const override
	Returns all available screens.

void	sendEvent (Core::View , QEvent ) const override

void	setCursorPos (QPoint) override

void	setMouseCursor (Qt::CursorShape, bool discardLast=false) override
	Sets the mouse cursor to the specified shape, this has an application-wide effect Call restoreMouseCursor() to set the previous cursor shape.

bool	supportsAeroSnap () const override
	Only supported on Qt, for windows.

QVector< std::shared_ptr< Core::Window > >	windows () const override
	Returns all windows.

Public Member Functions inherited from KDDockWidgets::Core::Platform
virtual void	dumpManagedBacktrace ()
	For non-C++, managed languages (having a VM) prints a non-native back-trace For example, the flutter frontend implements this to get a dart backtrace Used for debugging only. Can be called by gdb.

virtual bool	hasActivePopup () const
	Returns whether a popup is open Usually not needed to override. Investigate further in case side bars aren't auto hiding.

virtual bool	inDisallowedDragView (Point globalPos) const =0
	Returns whether the specified global position is on top of a view that isn't draggable. This is needed since not the entire title bar is draggable. For example, clicking on the close button shouldn't start a drag.

void	installGlobalEventFilter (EventFilterInterface *)
	Installs a global event filter Events will be forwarded to the specified EventFilterInterface.

bool	isQt () const
	Returns whether this platform is Qt based.

bool	isQtQuick () const
	Returns whether this platform is QtQuick.

bool	isQtWidgets () const
	Returns whether this platform is QtWidgets.

virtual void	onFloatingWindowCreated (Core::FloatingWindow *)
	Called when a floating window is created. Overridden by flutter, so it can create a window.

virtual void	onFloatingWindowDestroyed (Core::FloatingWindow *)
	Called when a floating window is created. Overridden by flutter, so it can destroy the window.

virtual void	onMainWindowCreated (Core::MainWindow *)
	Called when a main window is created. Overridden by flutter, so it can create a window Used by tests only. In real life users will instantiate a MainWindow in dart directly.

virtual void	onMainWindowDestroyed (Core::MainWindow *)
	Called when a main window is created. Overridden by flutter, so it can destroy the window.

void	removeGlobalEventFilter (EventFilterInterface *)
	Removes a global event filter.

virtual void	sendEvent (View , Event ) const =0
	Sends the specified event to the specified view.

virtual void	setCursorPos (Point)=0
	Sets the mouse cursor position in screen coordinates.

int	startDragDistance () const
	Returns how many pixels the mouse must move for a drag to start This is usually 4 by default (QApplication::startDragDistance() for QtWidgets) You can override by calling Config::setStartDragDistance(), so you don't need to create a new Platform class.

virtual std::shared_ptr< Core::Window >	windowAt (Point globalPos) const =0
	Returns the window at the specified global coordinates.
