define the API for widget / widget representation
vtkWidgetRepresentation * WidgetRep
abstract class for representing widget handles
a general widget for moving handles
a simple class to control print indentation
Definition: vtkIndent.h:113
platform-independent render window interaction including picking and frame rate control.
abstract specification for renderers
Definition: vtkRenderer.h:182
represent the vtkSeedWidget
place multiple seed points
virtual void CompleteInteraction()
Method to be called when the seed widget should stop responding to the place point interaction.
void DeleteSeed(int n)
Delete the nth seed.
static void EndSelectAction(vtkAbstractWidget *)
~vtkSeedWidget() override
vtkHandleWidget * GetSeed(int n)
Get the nth seed.
void SetProcessEvents(vtkTypeBool) override
Methods to change the whether the widget responds to interaction.
vtkSeedList * Seeds
static void CompletedAction(vtkAbstractWidget *)
void CreateDefaultRepresentation() override
Create the default widget representation if one is not set.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for a VTK class.
void SetEnabled(int) override
The method for activating and deactivating this widget.
virtual void RestartInteraction()
Method to be called when the seed widget should start responding to the interaction.
static void MoveAction(vtkAbstractWidget *)
void SetInteractor(vtkRenderWindowInteractor *) override
