Member Function Documentation

DtWidgetPicker& makVrv::DtWidgetPicker::operator= ( const DtWidgetPicker & rhs )

delete

not allowed

virtual unsigned int makVrv::DtWidgetPicker::numberOfWidgets ( ) const

virtual

Get the number of widgets.

virtual void makVrv::DtWidgetPicker::releaseResources ( bool renderer )

virtual

Deallocate any resources. Renderer boolean is part of a hack to get widgets pickable again.

virtual DtFrameBufferObject* makVrv::DtWidgetPicker::frameBufferObject ( void )

virtual

virtual DtPickableQuad* makVrv::DtWidgetPicker::allocatePickableQuad ( )

virtual

Allocate a widget quad, delete when done.

virtual DtPickableTriangle* makVrv::DtWidgetPicker::allocatePickableTriangle ( )

virtual

Allocate a widget quad, delete when done.

virtual DtPickableLine* makVrv::DtWidgetPicker::allocatePickableLine ( )

virtual

Allocate a widget quad, delete when done.

virtual DtPickableDecalProjector* makVrv::DtWidgetPicker::allocatePickableDecalProjector ( DtDecalProjectorComponentInterface * component )

virtual

Allocate a widget decal projector, delete when done.

virtual void makVrv::DtWidgetPicker::registerPickableDecalProjector ( DtPickableDecalProjector * widget )

virtual

Registers the pickable decal projector widget with this picker. The picker does not own the widget. The widget will call this in it's constuctor (no need to call it manually).

virtual void makVrv::DtWidgetPicker::unregisterPickableDecalProjector ( DtPickableDecalProjector * widget )

virtual

Unregisters the pickable decal projector widget with this picker. The picker does not own the widget. The widget will call this in it's deconstuctor (no need to call it manually).

virtual bool makVrv::DtWidgetPicker::requiresScenePick ( ) const

virtual

Returns true if this widget picker requires a scene pick prior to calling the pick method. This is used for recording a support node hit location from the mouse cursor position.

virtual void makVrv::DtWidgetPicker::pick	(	const MousePickRecord &	rec,
		bool	geocentric,
		double	cameraPosition[3],
		const DtObserverRenderData &	observerRenderData,
		double	cameraMatrix[16],
		const int	viewport[4]
	)

virtual

Pick at (int x, int y); As picking can be slow, start your pick, after updates but before rendering.

Parameters

viewport[4] - the viewport position and dimensions (x, y, width, height)

virtual const DtPickableWidget* makVrv::DtWidgetPicker::findWidgetFromLastPick ( ) const

virtual

Attempt to get the widget from the last pick.

virtual bool makVrv::DtWidgetPicker::signalEvents ( )

virtual

Done during the update phase.

Reimplemented in makVrf::DtVrfWidgetPicker.

virtual void makVrv::DtWidgetPicker::clearEvents ( )

virtual

Clear any pending events.

virtual DtPickableWidget* makVrv::DtWidgetPicker::calculateWidgetFromLastPick ( )

protectedvirtual

Get the widget at last pick. After rendering process the last pick.

virtual void makVrv::DtWidgetPicker::debugRender ( )

protectedvirtual

virtual DtQuadProxy* makVrv::DtWidgetPicker::allocateQuad ( )

protectedvirtual

Allocate a widget quad, delete when done.

virtual DtLineSegment* makVrv::DtWidgetPicker::allocateLine ( )

protectedvirtual

Allocate a widget quad, delete when done.

virtual DtTriangleProxy* makVrv::DtWidgetPicker::allocateTriangle ( )

protectedvirtual

Allocate a triangle.

virtual unsigned int makVrv::DtWidgetPicker::widgetCreated ( DtPickableWidget * )

protectedvirtual

Called when a widget is created.

virtual void makVrv::DtWidgetPicker::widgetToBeDeleted ( DtPickableWidget * )

protectedvirtual

Called when a widget is to be deleted.

virtual bool makVrv::DtWidgetPicker::allocateResources ( )
