Action Listeners

[Kapper Michael G Civ AFRL/PRSA]

Thanks Bill, PickManipulationRendererJ3D is exactly what I was looking
for.  But I'm still having an issue with how doAction() is triggered.  I
would like it to be triggered only when the reference is right-clicked,
but now it is being called (I'm assuming) anytime one of its attributes
changes (eg. position).  I did find a way around this by using the
getCloseIndex() method as follows.



pmr = new PickManipulationRendererJ3D();



cell = new CellImpl()

{   public void doAction() throws RemoteException, VisADException

    {   if( pmr.getCloseIndex() > -1 )

        {   

            ...

        }

    }

}



This way I'm sure that doAction() is triggered only when the reference
was right-clicked.  However, there are some caveats when I try to make
things a bit more complex which I think will be eliminated if doAction()
is only triggered by a right click.  Is there a way to stop doAction()
in all cases other than a right click?  Do I have to create my own
custom renderer?



Thanks again,

Mike

Hi Mike,

visad/bom/PickManipulationRendererJ3D.java may do
what you want. You can run:

  java visad.bom.PickManipulationRendererJ3D

to get a demo. Click the right mouse button on various
objects in the scene. You won't change their values, but
will trigger events.

Good luck,
Bill

Hi everyone,



I've been playing around with the DirectManipulationRenderer's and the
various Action implementations as in Ugo Taddei's tutorial.  Very cool
stuff, but I need to add a listener that would trigger the doAction()
method for specific events, not just when a point is moved.  For
example, I want to have a surface or line defined by a GriddedSet which
could be right-clicked to bring up a dialog box.  Is there an easy way
to do this?



Thanks,

Mike
