[vtkusers] Fullscreen with Qt

[Ignacio Fernández Galván]

Hi,

Is it possible to toggle some kind of fullscreen mode on and off in a 
QVTKRenderWindowInteractor?  When I call FullScreenOn() on the render 
window I get two problems:

1. There's no mouse interaction at all.

2. With two monitors the fullscreen mode spans both monitors, I'd prefer 
it to be limited to one, like the maximize button of normal windows.

Of course, it's #1 which is critical.

It seems ParaView uses some trick creating a second window that goes 
fullscreen... I've been more successful trying this: I created a QDialog 
with another VTK widget, used its showFullScreen() method, hid the 
previous widget, transferred the renderer to the new window... This more 
or less works, and I get mouse interaction, but when I close this second 
dialog and show again the old widget, it's dead, with no interaction.

Has anyone managed to do this? Can you show me an example, preferably in 
python? Any important step I'm missing?

Thanks,
Ignacio
