[vtkusers] Is vtkPanel in vtk4.0 a Swing Component ?

[Ken Martin]

The VTKPanel window is an OpenGL window (it uses OpenGL hardware to
render). OpenGL windows cannot be swing components as far as I know.
This is a limitation of mixing any OpenGL window (aka heavyweight)
with any lightweight widget approach (mainly swing since most others
such as Tk/MFC etc are heavyweight). You could open an OpenGL window
in memory, render to memory and then paste the result up as an image
which would work with swing, but then you loose most of the
acceleration from the 3D hardware. Java3D has the exact same problem
and I don't expect any solution in the near future.
