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 void makVrv::DtWidgetPicker::pick ( const MousePickRecord &  rec, bool  geocentric, double  cameraPosition[3], double  cameraAltitude, double  cameraMatrix[16]  )

virtual

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

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 DtQuad* 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 ( )
