Re: Mouse Interactions with VisAD

Hi Yuan,

You can do this by extending two classes (assuming you are using Java3D
for Displays):

  visad/java3d/DefaultDisplayRendererJ3D.java
  visad/java3d/MouseBehaviorJ3D.java

The extension of DefaultDisplayRendererJ3D would override
createSceneGraph, that would differ from
DefaultDisplayRendererJ3D.createSceneGraph in that it constructs
the extension of MouseBehaviorJ3D rather than MouseBehaviorJ3D.

The extension of MouseBehaviorJ3D would override processStimulus,
that would scan the AWTEvents in its 'Enumeration criteria' argument
looking for MouseEvents, then invoke 'super.processStimulus(criteria)'
to let MouseBehaviorJ3D.processStimulus do its work.

Please let me know if you have problems.

Cheers,
Bill
