[vtkusers] QVtkWidgets in a QGraphicsView (QGraphicsScene)

[J.S.Wijnhout at lumc.nl]

Hi,

Sounds like an interesting example!

It can't seem to get it to work properly (using Qt 4.4.3 and VT 5.2.0). When I run the example the standard vtkRenderWindow is displayed but the Qt widget doesn't show. Also I get many errors on the console (see at the end of this message). Should I use the CVS version of VTK?

Best,
Jeroen
