define the API for widget / widget representation
vtkWidgetRepresentation * WidgetRep
provide the representation for a continuous value
set a value by manipulating something
static void MoveAction(vtkAbstractWidget *)
void SetValue(double v)
Get the value for this widget.
vtkContinuousValueWidgetRepresentation * GetContinuousValueWidgetRepresentation()
Return the representation as a vtkContinuousValueWidgetRepresentation.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard macros.
static void SelectAction(vtkAbstractWidget *)
~vtkContinuousValueWidget() override=default
double GetValue()
Get the value for this widget.
static void EndSelectAction(vtkAbstractWidget *)
void SetRepresentation(vtkContinuousValueWidgetRepresentation *r)
Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene.
