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 *)
void SetCursor(int state) override
static void MoveAction(vtkAbstractWidget *)
void SetRepresentation(vtkAffineRepresentation *r)
Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene.
static vtkAffineWidget * New()
Instantiate this class.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
