[vtkusers] VTK with FLTK/Qt problem

[Julien Jomier]

Hi all,

I'm having a strange problem using VTK with FLTK (same problem with Qt)
I have a simple window with two VTK displays in it.

Each display shows a different VTK actor.
The first time the window is shown everything looks fine. but when I do
a refresh of one of the windows, the actor is not displayed anymore and
the other display turns black (background color) too.

The strange thing is that when the two displays (vtkRenderWindow) have
the same actor, everything is fine.

I'm using VisualC++/Window2K with VTK4

Thanks for your help

Julien
