[Qt-interest] Transparent background QVtkWidget

[Guillaume DARDENNE]

Dear Qt users,


I use QVtkWidget in order to display a 3D vtk scene.
I would like to make the background of the vtkwidget transparent.

I know that there is a function setWindowOpacity() for this but it doesn't
work (I have a black background).

Can you help me ?

Thank you very much for your answers.
