define the API for widget / widget representation
vtkWidgetRepresentation * WidgetRep
represent the vtkCheckerboardWidget
interactively set the number of divisions in 2D image checkerboard
void SetRepresentation(vtkCheckerboardRepresentation *r)
Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene.
~vtkCheckerboardWidget() override
static vtkCheckerboardWidget * New()
Instantiate this class.
void EndCheckerboardInteraction()
void CheckerboardInteraction(int sliderNum)
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for a VTK class.
void CreateDefaultRepresentation() override
Create the default widget representation if one is not set.
void StartCheckerboardInteraction()
void SetEnabled(int) override
The method for activating and deactivating this widget.
vtkCheckerboardRepresentation * GetCheckerboardRepresentation()
Return the representation as a vtkCheckerboardRepresentation.
a simple class to control print indentation
Definition vtkIndent.h:40
set a value by manipulating a slider
abstract class defines interface between the widget and widget representation classes
