[vtkusers] QVTKWidget vs QVTKOpenglWidget vs QVTKWidget2

[minjun]

I want to have qvtkwidget as background and place a generic QWidget on top of
it.

However, when I place a generic qwidget, the widget looks like to stop or
not work properly.

I came to know through many searches that this is a opengl context problem.

So some people advice me to use QWidget2 or QVTKOpenglWidget to solve this
problem.

Is this the right way?

If you have any experience like this, I would like to get some advice. Thank
you.
