Detailed Description

interactively control an instance of vtkImageRectilinearWipe filter

The vtkRectilinearWipeWidget is used to interactively control an instance of vtkImageRectilinearWipe (and an associated vtkImageActor used to display the rectilinear wipe). A rectilinear wipe is a 2x2 checkerboard pattern created by combining two separate images, where various combinations of the checker squares are possible. Using this widget, the user can adjust the layout of the checker pattern, such as moving the center point, moving the horizontal separator, or moving the vertical separator. These capabilities are particularly useful for comparing two images.

To use this widget, specify its representation (by default the representation is an instance of vtkRectilinearWipeProp). The representation generally requires that you specify an instance of vtkImageRectilinearWipe and an instance of vtkImageActor. Other instance variables may also be required to be set – see the documentation for vtkRectilinearWipeProp (or appropriate subclass).

By default, the widget responds to the following events:

Selecting the center point, horizontal separator, and verticel separator:
  LeftButtonPressEvent - move the separators
  LeftButtonReleaseEvent - release the separators
  MouseMoveEvent - move the separators

Selecting the center point allows you to move the horizontal and vertical separators simultaneously. Otherwise only horizontal or vertical motion is possible/

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

  vtkWidgetEvent::Select -- some part of the widget has been selected
  vtkWidgetEvent::EndSelect -- the selection process has completed
  vtkWidgetEvent::Move -- a request for motion has been invoked

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

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

Warning: The appearance of this widget is defined by its representation, including any properties associated with the representation. The widget representation is a type of vtkProp that defines a particular API that works with this widget. If desired, the vtkProp may be subclassed to create new looks for the widget.
