Detailed Description

3D widget for performing 3D transformations around an axes

This 3D widget defines an axes which is used to guide transformation. The widget can translate, scale, and rotate around one of the three coordinate axes. The widget consists of a handle at the origin (used for translation), three axes (around which rotations occur), and three end arrows (or cones depending on the representation) that can be stretched to scale an object. Optionally a text label can be used to indicate the amount of the transformation.

To use this widget, you generally pair it with a vtkAxesTransformRepresentation (or a subclass). Various options are available in the representation for controlling how the widget appears, and how the widget functions.

Event Bindings:

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

If the origin handle is selected:
  LeftButtonPressEvent - activate the associated handle widget
  LeftButtonReleaseEvent - release the handle widget associated with the point
  MouseMoveEvent - move the handle and hence the origin and the widget
If one of the lines is selected:
  LeftButtonPressEvent - activate rotation by selecting one of the three axes.
  LeftButtonReleaseEvent - end rotation
  MouseMoveEvent - moving along the selected axis causes rotation to occur.
If one of the arrows/cones is selected:
  LeftButtonPressEvent - activate scaling by selecting the ends of one of the three axes.
  LeftButtonReleaseEvent - end scaling
  MouseMoveEvent - moving along the selected axis causes scaling to occur.

Event Bindings:

Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkAxesTransformWidget'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 slider motion has been invoked

Event Bindings:

In turn, when these widget events are processed, the vtkAxesTransformWidget 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)

Warning: Note that the widget can be picked even when it is "behind" other actors. This is an intended feature and not a bug.; This class, and vtkAxesTransformRepresentation, are next generation VTK widgets.
