All known Subclasses: com.db.behaviors.ExamineViewerBehavior, com.db.behaviors.WalkViewerBehavior, com.db.behaviors.FlyViewerBehavior,
| ViewerBehavior | | abstract public class ViewerBehavior extends Behavior (Code) | | Wakeup on mouse button presses, releases, and mouse movements and
generate transforms for a transform group. Classes that extend this
class impose specific symantics, such as "Examine" or "Walk" viewing,
similar to the navigation types used by VRML browsers.
To support systems with 2 or 1 mouse buttons, the following
alternate mappings are supported while dragging with any mouse
button held down and zero or more keyboard modifiers held down:
No modifiers = Button 1
ALT = Button 2
Meta = Button 3
Control = Button 3
The behavior automatically modifies a TransformGroup provided
to the constructor. The TransformGroup's transform can be set
at any time by the application or other behaviors to cause the
viewer's rotation and translation to be reset.

|
| onButton1 | | abstract public void onButton1(MouseEvent mouseEvent)(Code) | | Respond to a button1 event (press, release, or drag).
Parameters:
mouseEvent - A MouseEvent to respond to. |
| onButton2 | | abstract public void onButton2(MouseEvent mouseEvent)(Code) | | Respond to a button2 event (press, release, or drag).
Parameters:
mouseEvent - A MouseEvent to respond to. |
| onButton3 | | abstract public void onButton3(MouseEvent mouseEvent)(Code) | | Responed to a button3 event (press, release, or drag).
Parameters:
mouseEvent - A MouseEvent to respond to. |
| onElapsedFrames | | abstract public void onElapsedFrames(WakeupOnElapsedFrames timeEvent)(Code) | | Respond to an elapsed frames event (assuming subclass has set up a
