[PyKDE] PyQT and VTK, problem with layout management

[CEZARD Yann]

Hi !

Not sure if this more a QT or VTK related question, but
perhaps someone here has the solution, so I make a cross-posting.

I'm using the QT designer to design a GUI, and using another
kind of widget (QFrame or QLabel) in order to position my futur
QVTKRenderWidget (a widget that inherits QWidget ans that is used
to display VTK data) by then editing the output code and replacing
the QFrame by the QVTKRenderWidget, but here is my problem :

If I don't use the possibilities of layout management of QT,
everythings goes OK, but if I do, the main window doesn't
display at all...
I think it's a problem of methods that are not implemented by
the QVTKRenderWidget, but which ones ?
Does anybody here have an idea ? Did someone already resolve
this kind of problem ?

Sorry if I am out of topic...

Thanks,

Yann Cézard
