Hi Joachim,
This is a bug in the MouseBehavior() utility.
Bug 4465262 - MouseBehavior postID not work after
behavior disable and enable again
is filed for this. A workaround is to use WakeupOnAWTEvent
instead of AWT listeners and behavior posts.
i.e. use MouseBehavior() instead of MouseBehavior(Component c)
constructor.
But if WakeupOnAWTEvent is used, the first click will be igored
after enable again, see bug 4391507.
You can simply fix the utility by editing the source provided
in the SDK download under
com/sun/j3d/utils/behaviors/mouse/MouseBehavior.java
and remove the checking mouseq.size() == 1 :
if (mouseq.size() == 1)
postId(MouseEvent.MOUSE_DRAGGED);
A better fix would be to prevent event adding to the queue
when behavior disable.
Thanks for your test program.
