define the API for widget / widget representation
vtkWidgetRepresentation * WidgetRep
represent a vtkBorderWidget
place a border around a 2D rectangular region
virtual void CreateDefaultRepresentation()
Create the default widget representation if one is not set.
static void SelectAction(vtkAbstractWidget *)
static void TranslateAction(vtkAbstractWidget *)
virtual void SetCursor(int State)
virtual void SelectRegion(double eventPos[2])
Subclasses generally implement this method.
static vtkBorderWidget * New()
Method to instantiate class.
vtkBorderRepresentation * GetBorderRepresentation()
Return the representation as a vtkBorderRepresentation.
void PrintSelf(ostream &os, vtkIndent indent)
Methods invoked by print to print information about the object including superclasses.
virtual int SubclassSelectAction()
static void EndSelectAction(vtkAbstractWidget *)
virtual int SubclassMoveAction()
virtual int SubclassEndSelectAction()
virtual int SubclassTranslateAction()
void SetRepresentation(vtkBorderRepresentation *r)
Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene.
static void MoveAction(vtkAbstractWidget *)
a simple class to control print indentation
Definition: vtkIndent.h:40
abstract class defines interface between the widget and widget representation classes
vtkSetMacro(IgnoreDriverBugs, bool)
Updates the extensions string.
vtkBooleanMacro(IgnoreDriverBugs, bool)
Updates the extensions string.
