Member Function Documentation

osgViewer::GraphicsWindow* makVrv::DtOsgAdapterQtWidget::graphicsWindow ( )

Get the Graphics Window.

void makVrv::DtOsgAdapterQtWidget::setView ( DtWindow * window )

Set the osg window to forward off events such as resize.

DtWindow* makVrv::DtOsgAdapterQtWidget::view ( ) const

int makVrv::DtOsgAdapterQtWidget::widgetToNativeCoordinate ( int widgetValue )

Converts a point in possibly scaled widget coordinates to native coordinates to support Qt high dpi scaling.

Returns: widgetValue multiplied by devicePixelRatio. On unscaled content devicePixelRatio is 1.

int makVrv::DtOsgAdapterQtWidget::nativeToWidgetCoordinate ( int nativeValue )

Converts a point in native coordinates to possibly scaled widget coordinates to support Qt high dpi scaling.

Returns: widgetValue multiplied by devicePixelRatio. On unscaled content devicePixelRatio is 1.

virtual osgGA::GUIEventAdapter::KeySymbol makVrv::DtOsgAdapterQtWidget::osgKeyFromQtKeyEvent ( QKeyEvent * event )

virtual

maps keys coming from Qt to osg::GuiEventAdapter::KeySymbols

virtual void makVrv::DtOsgAdapterQtWidget::processKeyPressEvent ( QKeyEvent * keyEvent )

virtual

process a key press event that came from Qt directly or from the key adapter

virtual void makVrv::DtOsgAdapterQtWidget::processKeyReleaseEvent ( QKeyEvent * keyEvent )

virtual

process a key release event that came from Qt directly or from the key adapter

virtual bool makVrv::DtOsgAdapterQtWidget::processTouchEvent ( QTouchEvent * touchEvent )

virtual

Process a touch event. Touch events with two touchpoints are treated as pinches; others are ignored (exception - touch end events always have one touchpoint, even if its the end of a multitouch event; hence it is processed here IF we are current within an identified pinch gesture)

virtual void makVrv::DtOsgAdapterQtWidget::mouseMoveEvent ( QMouseEvent * event )

virtual

virtual void makVrv::DtOsgAdapterQtWidget::focusInEvent ( QFocusEvent * event )

virtual

virtual void makVrv::DtOsgAdapterQtWidget::focusOutEvent ( QFocusEvent * event )

virtual

virtual bool makVrv::DtOsgAdapterQtWidget::event ( QEvent * event )

virtual

static QGLFormat makVrv::DtOsgAdapterQtWidget::createFormatFromTraits ( const osg::GraphicsContext::Traits * contextTraits )

static

Helper function to create a QFormat from an osg context traits.

virtual QSize makVrv::DtOsgAdapterQtWidget::sizeHint ( ) const

virtual

virtual void makVrv::DtOsgAdapterQtWidget::slot_onRightClickTerrainMenuRequest	(	double	mouseX,
		double	mouseY,
		DtChannel *	channel
	)

virtual

called by signal requesting a terrain-specific popup menu

virtual void makVrv::DtOsgAdapterQtWidget::slot_onRightClickSelectionMenuRequest	(	double	mouseX,
		double	mouseY,
		DtChannel *	channel
	)

virtual

called by signal requesting a selection-specific popup menu

virtual void makVrv::DtOsgAdapterQtWidget::slot_onWindowConfigurationModified ( const DtWindowConfiguration & newWindowConfig )

virtual

called by signal indicating a window configuration change

void makVrv::DtOsgAdapterQtWidget::devicePixelRatioChanged ( )

signal

This signal is emitted when the high dpi scaling factor changes.

void makVrv::DtOsgAdapterQtWidget::init ( )

protected

virtual bool makVrv::DtOsgAdapterQtWidget::channelInThisWidget ( const DtChannel & channel )

protectedvirtual

Find out if our window (myView) owns a channel. Used when processing ctrlEnter signals.

protectedvirtual

virtual void makVrv::DtOsgAdapterQtWidget::getTouchPointPositions	(	const QTouchEvent &	touchEvent,
		osg::Vec2 &	p0,
		osg::Vec2 &	p1
	)

protectedvirtual

Get the positions of the 2 touch points in a touch event; if the touch event has no touch points, p0 and p1 will be untouched. If the touch event has only one touch point, p0 will be set and p1 will be untouched.

virtual void makVrv::DtOsgAdapterQtWidget::startOsgTouch	(	const osg::Vec2 &	p0,
		const osg::Vec2 &	p1
	)

protectedvirtual

This creates an osgGA GUI Adapter touch event with the Began phase and the points provided.

virtual void makVrv::DtOsgAdapterQtWidget::continueOsgTouch	(	const osg::Vec2 &	p0,
		const osg::Vec2 &	p1
	)

protectedvirtual

This creates an osgGA GUI Adapter touch event with the Moved phase and the points provided.

virtual void makVrv::DtOsgAdapterQtWidget::endOsgTouch ( const osg::Vec2 & p0 )

protectedvirtual

This creates an osgGA GUI Adapter touch event with the Ended phase and the points provided.

virtual void makVrv::DtOsgAdapterQtWidget::cleanupOpenGlResources ( void )

protectedvirtual

This is called from the destructor -It saves the incoming OpenGL context (it may or may not be this widget's context) -It makes the context for this widget current. -It then calls DtOsgToGlContextTracker::instance(myDe).contextAboutToBeDestroyed -Then, the incoming OpenGL context is resotred.

void makVrv::DtOsgAdapterQtWidget::emit_signal_pixelRatioChanged ( )

protectedslot

Simple wrapper to emit boost pixelRatioChanged signal from the Qt signal.
