Detailed Description

Abstract base interface for wrappers of a Display that embed them in a Qt-based GUI application.

Public Member Functions
	QtDisplayWrapperBase (Display &display)
	Constructor will subscribe to the Display::signalUpdateRequested signal.
Display &	display ()
	Returns the Display shown by this widget.
QPointF	mapFromOpenGL (const vec2 &point) const
	Converts point from ImFusion::GUI's bottom-left-origin coordinates to Qt's top-left-origin coordinates.
vec2	mapToOpenGL (const QPointF &point) const
	Converts point from Qt's top-left-origin coordinates to ImFusion::GUI's bottom-left-origin coordinates.
virtual QPointF	mapToGlobal (const QPointF &pos) const =0
	Implementations shall forward to Qt's mapToGlobal() function of the wrapper class.
Public Member Functions inherited from ImFusion::SignalReceiver
	SignalReceiver ()=default
	Default constructor.
	SignalReceiver (const SignalReceiver &other)
	Copy constructor, does not copy any existing signal connections from other.
SignalReceiver &	operator= (SignalReceiver rhs)
	Assignment operator, disconnects all existing connections, does not copy any existing signal connections from rhs.
virtual	~SignalReceiver ()
	Virtual destructor disconnects from all connected signals.

Protected Member Functions
bool	handleInputEvent (QEvent *event)
virtual void	onDisplayUpdateRequested ()=0
	Implementations shall make Qt rerender the display.
virtual double	getDevicePixelRatio () const =0
	Return the device pixel ratio of the screen the display is shown on.
virtual int	getHeight () const =0
	Return the height of the display wrapper in pixels.
virtual void	setCursor (const QCursor &cursor)=0
	Implementations shall forward to Qt's setCursor() function of the wrapper class.
Protected Member Functions inherited from ImFusion::SignalReceiver
void	disconnectAll ()
	Disconnects all existing connections.
