[vtkusers] Swing Based vtkPanel

[Satheesh Maheswaran]

hello users

I am trying to get vtkPanel.java work with SimpleVTK.java given with VTK. Its in
vtk/wrapping/java

All works, and the panel gets displayed with cone and an exit button.  Here awt and swing
components are mixed, and the vtkPanel.java extends Canvas, which I think is awt.

So when i run it and try to interact with it, all key events work and the exit button work,
but when trying the mouse events. like zooming, it crashes :)

has anyone come across the same problem !!! or may be even a solution for the problem !!
