[vtkusers] removeActor() causes error ("wglMakeCurrent failed...")

[Sebastien Jourdain]

Hi Marcus,

Anyway, the main issue was that you overflow the EDT queue by calling
repaint() inside a paintXXX method.

What I meant before was, did you build your Swing components in the
EDT as it should be ? Which means, did you used
SwingUtility.invokeLater(....) ? And also is VTK is managed only by
only one thread ??? Normaly, bad management of java thread with VTK
imply a crash, but it could also have been a cause of paint error...

Seb

EDT = Event Dispatch Thread
