GUIEventHandler provides a basic interface for any class which wants to handle
|
|
a GUI Events.
|
|
|
|
The GUIEvent is supplied by a GUIEventAdapter. Feedback resulting from the
|
|
handle method is supplied by a GUIActionAdapter, which allows the GUIEventHandler
|
|
to ask the GUI to take some action in response to an incoming event.
|
|
|
|
For example, consider a Trackball Viewer class which takes mouse events and
|
|
manipulates a scene camera in response. The Trackball Viewer is a GUIEventHandler,
|
|
and receives the events via the handle method. If the user 'throws' the model,
|
|
the Trackball Viewer class can detect this via the incoming events, and
|
|
request that the GUI set up a timer callback to continually redraw the view.
|
|
This request is made via the GUIActionAdapter class.
