[vtkusers] size of QVTKWidget

[Anja Ende]

Hi Clint,

Thanks for your reply. I really tried calling ensurePolished() and it still
returns the same window size.

Actually if I query the window size after the exec() has returned, then it
returns the correct value... But my then it is too late :(

Here is a bit of code, to see when I am actually querying for the size...

QHBoxLayout * mainLayout = new QHBoxLayout;
mainLayout->addLayout(viewersLayout);
mainLayout->addLayout(toolbarLayout);

mainWindow.AddLayout(mainLayout);
mainWindow.Pack();
// As you can see, I call show before I query the size...
mainWindow.showFullScreen();

// totally bogus values....
int * size = xyViewer->GetSize();

Is there a way yo override some of these creation events....???

Cheers and thanks,

Anja
