[vtkusers] Problem about vtkPanel

[Jeff Lee]

Hi,
you can't do that easily.  vtkPanel contains native methods which have a 
specific mangled signature in c++ code.  i would suggest either 
subclassing, or making your own vtkPanel which overrides the existing 
one.  if you have your own vtk distribution, you could however change 
vtkJavaAwt.h and mangle the method names to match your modified one.
