[vtkusers] Java RemoveActors

[Jeff Lee]

Hi Richard,
Try something like

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
          Lock();
          currentRenderer.RemoveProp(act);
          UnLock();
        }
      });

If you are using vtkPanel, you could sublcass it, and add a method to do 
this (Lock and UnLock are protected).  HTH,
-Jeff
