[vtkusers] Re : VTKPanel +Swing - repainting issue

[Markus Ott]

Hi Jerome,

thank you for your quick reply.
The application is running on a Windows Vista machine.

I use a simple BorderLayout with vtkPanel at BorderLayout.CENTER and the
infoPanel at BorderLayout.LINE_START.

Overriding removeNotify() as in http://www.vtk.org/Bug/view.php?id=7107
doesn't help here.
