[vtkusers] qvtkWidget as separate window

[Jon Agirre]

Hi Doug,

thanks for your reply. I've been able to figure this out myself, according
to Murphy's Law of Support Mailing Lists (Despite having spent two weeks on
one problem, you only get to solve it right after asking for help in the
appropriate mailing list).

The solution seems to be to add the qvtkWidget to a separate QWidget, which
acts as a window. There were two problems: 1) qvtkWidget's parent should be
the widget I'm summoning to act as separate window. 2) In the QWidget's
creator, the flags should be adjusted to something sensible, i.e.
Qt::Dialog. I had them set as Qt::Window.

Thanks!

Jon
