[vtkusers] Re: Best vtk / QT package?

[Stefan Bruckner]

Ok, I included the essential parts of my classes in this mail. It's very
easy.
This requires VTK_QT
(http://wwwipr.ira.uka.de/~kuebler/vtkqt/index.html) in your project.

There are two classes: jzRenderFrame (derived from QFrame), a framed
widget that resizes the vtkRenderWindow when it is resized.

vtkRenderWidget contains a QGridLayout which can contain as many
jzRenderFrames (as well es other elements) as you want.

I hope this helps you!
