[vtkusers] Vtk on linux

[Bruno]

Hello,

I want to create a program using C++ and VTK on Linux, using a visual 
interface on KDE. I tried the sphere example with KDevelop and QT. It 
worked, but when I press the button to show the Render Window, the main 
window of my program and all of its buttons become unvaliable, i.e, I 
can't push any other button or access any menu of the window. To do 
these things, I must close the Render Window. What should I do to solve 
this problem?

thanks,
Bruno.
