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)

void makVrv::DtOsgAdapterQtWidget::devicePixelRatioChanged ( )

signal

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

	)

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.
