[vtkusers] qcombobox as a child of qvtkwidget doesn't show up on mac.

[Simon ESNEAULT]

Hello,

Well from my experience, it's is not easy to draw a qt widget on top of a
QVTKWidget, especially on OSX.
You can try to add some Qt flags (Qt::Tool or Qt::WindowStaysOnTopHint) to
the combobox. This may or not work, depending the version of Qt you're
running, and it may also introduce some weird behavior ...

I would rather advice you put the widget beside the QVTKWidget, in a
vertical/horizontal layout, or you use some of VTK widget if you really
want to draw within the view (use a TextureButton together with a qt popup
menu for example)

Good luck
Simon
