Jim, et al-
Since that message was written, the ability to get events
from other Mouse movements has been added. So, you could
do something like:
DisplayImpl display = new DisplayImplJ3D();
display.enableEvent(DisplayEvent.MOUSE_MOVED);
display.enableEvent(DisplayEvent.MOUSE_DRAGGED);
addDisplayListener(new DisplayListener() {
public void displayChanged(DisplayEvent event) {
int id = event.getId();
try {
if (id == event.MOUSE_MOVED) {
pointerMoved(event.getX(), event.getY());
}
}
}
});
where pointerMoved would be something like:
/**
* Handles a change in the position of the mouse-pointer.
*/
protected void pointerMoved(int x, int y)
throws UnitException, VisADException, RemoteException {
/*
* Convert from (pixel, line) Java Component coordinates to (latitude,
* longitude)
*/
VisADRay ray
display.getDisplayRenderer().getMouseBehavior().findRay(x,y);
<....code from Jim's example, using ray.position instead of
cursor location....>
}

Hello Oliver,
this question has come up before, so you can the previous

PS. I also use this method and it works well.
Hope this helps,
Jim.

Hi,
I have a fairly complex application producing several 2D visad plots.
I notice that clicking the middle mouse button on the plot prints the
current X,Y values for that point. I want to extend this so that I can
be notified or these x,y values when the user clicks on the plot and
then perform some additional tasks.
Is there a way to listen for this kind of event?
I have found that DisplayEvents are triggered when the user clicks on
the plot, but these events are only aware of the X,Y coors of the plot,
not the corresponding values.
I would very much appreciate any advice or tips.
Thanks, Oliver Mather
