virtual void SetCursor(int vtkNotUsed(state))
abstract class for representing affine transformation widgets
#define VTK_DEPRECATED_IN_9_2_0(reason)
void PrintSelf(ostream &os, vtkIndent indent) override
Standard macros implementing standard VTK methods.
virtual void CreateDefaultRepresentation()=0
Create the default widget representation if one is not set.
vtkWidgetRepresentation * WidgetRep
a simple class to control print indentation
Definition: vtkIndent.h:28
void SetRepresentation(vtkAffineRepresentation *r)
Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene...
perform affine transformations
define the API for widget / widget representation
void SetEnabled(int) override
Methods for activating this widget.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
vtkAffineRepresentation * GetAffineRepresentation()
Return the representation as a vtkAffineRepresentation.
