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:34
platform-independent render window interaction including picking and frame rate control.
abstract specification for renderers
Definition: vtkRenderer.h:68
represent the vtkSeedWidget
place multiple seed points
Definition: vtkSeedWidget.h:88
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.
vtkSeedRepresentation * GetSeedRepresentation()
Return the representation as a vtkSeedRepresentation.
static void EndSelectAction(vtkAbstractWidget *)
~vtkSeedWidget() override
static vtkSeedWidget * New()
Instantiate this class.
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
Methods invoked by print to print information about the object including superclasses.
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
Set the interactor.
static void AddPointAction(vtkAbstractWidget *)
void SetCurrentRenderer(vtkRenderer *) override
Set the current renderer.
static void DeleteAction(vtkAbstractWidget *)
vtkHandleWidget * GetSeed(int n)
Get the nth seed.
virtual vtkHandleWidget * CreateNewHandle()
Use this method to programmatically create a new handle.
void SetRepresentation(vtkSeedRepresentation *rep)
Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene.
abstract class defines interface between the widget and widget representation classes
