Detailed Description

a class defining the representation for a vtkQWidgetWidget

This class renders a QWidget as a simple vtkPlaneSource with a vtkTexture that contains a vtkQWidgetTexture which imports the OpenGL texture handle from Qt into the vtk scene. Qt and VTK may need to be useing the same graphics context.

SetInteractionState()

virtual void vtkQWidgetRepresentation::SetInteractionState ( int  )

virtual

The interaction state may be set from a widget (e.g., vtkQWidgetWidget) or other object.

This controls how the interaction with the widget proceeds. Normally this method is used as part of a handshaking process with the widget: First ComputeInteractionState() is invoked that returns a state based on geometric considerations (i.e., cursor near a widget feature), then based on events, the widget may modify this further.

Get the vtkPlaneSouce used by this representation.

This can be useful to set the Origin, Point1, Point2 of the plane source directly.

GetWidgetCoordinates() [1/3]

virtual float * vtkQWidgetRepresentation::GetWidgetCoordinates ( )

virtual

Get the widget coordinates as computed in the last call to ComputeComplexInteractionState.

GetWidgetCoordinates() [2/3]

virtual void vtkQWidgetRepresentation::GetWidgetCoordinates ( float &  , float &    )

virtual

GetWidgetCoordinates() [3/3]

virtual void vtkQWidgetRepresentation::GetWidgetCoordinates ( float  [2] )

virtual

RegisterPickers()

void vtkQWidgetRepresentation::RegisterPickers ( )

overrideprotectedvirtual

Register internal Pickers in the Picking Manager.

Must be reimplemented by concrete widget representations to register their pickers.

Reimplemented from vtkWidgetRepresentation.
