define the API for widget / widget representation
vtkWidgetRepresentation * WidgetRep
a simple class to control print indentation
Definition: vtkIndent.h:29
represent a vtkBorderWidget
create a moving, magnifying renderer that can inspect the contents of an encapsulating renderer.
void CreateDefaultRepresentation() override
Create the default widget representation if one is not set.
static void CharAction(vtkAbstractWidget *)
static vtkMagnifierWidget * New()
Method to instantiate class.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for class.
void SetEnabled(int enabling) override
Override superclasses' SetEnabled() method because the this widget must activate the representation.
~vtkMagnifierWidget() override
static void MoveAction(vtkAbstractWidget *)
void SetRepresentation(vtkMagnifierRepresentation *r)
Specify an instance of vtkMagnifierRepresentation used to represent this widget in the scene.
vtkMagnifierRepresentation * GetMagnifierRepresentation()
Return the representation as a vtkBorderRepresentation.
abstract class defines interface between the widget and widget representation classes
