Detailed Description

a general widget for moving handles

The vtkHandleWidget is used to position a handle. A handle is a widget with a position (in display and world space). Various appearances are available depending on its associated representation. The widget provides methods for translation, including constrained translation along coordinate axes. To use this widget, create and associate a representation with the widget.

Event Bindings:

By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):

  LeftButtonPressEvent - select focal point of widget
  LeftButtonReleaseEvent - end selection
  MiddleButtonPressEvent - translate widget
  MiddleButtonReleaseEvent - end translation
  RightButtonPressEvent - scale widget
  RightButtonReleaseEvent - end scaling
  MouseMoveEvent - interactive movement across widget

Event Bindings:

Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkHandleWidget's widget events:

  vtkWidgetEvent::Select -- focal point is being selected
  vtkWidgetEvent::EndSelect -- the selection process has completed
  vtkWidgetEvent::Translate -- translate the widget
  vtkWidgetEvent::EndTranslate -- end widget translation
  vtkWidgetEvent::Scale -- scale the widget
  vtkWidgetEvent::EndScale -- end scaling the widget
  vtkWidgetEvent::Move -- a request for widget motion

Event Bindings:

In turn, when these widget events are processed, the vtkHandleWidget invokes the following VTK events on itself (which observers can listen for):

  vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
  vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
  vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)

Events:: vtkCommand::DisableEvent vtkCommand::EndInteractionEvent vtkCommand::InteractionEvent vtkCommand::StartInteractionEvent
