void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for instances of this class.
virtual void StartWidgetInteraction(double eventPos[2])
abstract class defines interface between the widget and widget representation classes ...
provide the representation for a continuous value
a simple class to control print indentation
Definition: vtkIndent.h:39
void BuildRepresentation() override
Methods to interface with the vtkSliderWidget.
virtual void WidgetInteraction(double newEventPos[2])
virtual void PlaceWidget(double *vtkNotUsed(bounds[6]))
The following is a suggested API for widget representations.
