vtkWidgetRepresentation * WidgetRep
abstract class for representing affine transformation widgets
perform affine transformations
static void ModifyEventAction(vtkAbstractWidget *)
void SetEnabled(int) override
Methods for activating this widget.
void CreateDefaultRepresentation() override
Create the default widget representation if one is not set.
static void SelectAction(vtkAbstractWidget *)
