an abstract superclass for classes observing events invoked by vtkRenderWindowInteractor
vtkInteractorObserver is an abstract superclass for subclasses that observe events invoked by vtkRenderWindowInteractor. These subclasses are typically things like 3D widgets; objects that interact with actors in the scene, or interactively probe the scene for information.
vtkInteractorObserver defines the method SetInteractor() and enables and disables the processing of events by the vtkInteractorObserver. Use the methods EnabledOn() or SetEnabled(1) to turn on the interactor observer, and the methods EnabledOff() or SetEnabled(0) to turn off the interactor. Initial value is 0.
To support interactive manipulation of objects, this class (and subclasses) invoke the events StartInteractionEvent, InteractionEvent, and EndInteractionEvent. These events are invoked when the vtkInteractorObserver enters a state where rapid response is desired: mouse motion, etc. The events can be used, for example, to set the desired update frame rate (StartInteractionEvent), operate on data or update a pipeline (InteractionEvent), and set the desired frame rate back to normal values (EndInteractionEvent). Two other events, EnableEvent and DisableEvent, are invoked when the interactor observer is enabled or disabled.

Set/Get the priority at which events are processed.
This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.) Note that when multiple interactor observer have the same priority, then the last observer added will process the event first. (Note: once the SetInteractor() method has been called, changing the priority does not effect event processing. You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)

These methods enable an interactor observer to exclusively grab all events invoked by its associated vtkRenderWindowInteractor.
(This method is typically used by widgets to grab events once an event sequence begins.) The GrabFocus() signature takes up to two vtkCommands corresponding to mouse events and keypress events. (These two commands are separated so that the widget can listen for its activation keypress, as well as listening for DeleteEvents, without actually having to process mouse events.)
