[vtkusers] QVTKOpenGLWidget and QWidgets

[Sam Raby]

Let me rephrase the issue that I am observing. I run the following vtk
example that uses QVTKOpenGLWidget in Qt Creator. I can successfully run
the example. Then I added one simple QCheckBox to UI. I can compile the
code but the checkbox does not respond to mouse clicking, meaning that If I
click on the checkbox it does not get checked, but if I interact with
the QVTKOpenGLWidget
it causes the checkbox to be updated. Is that a bug? because what I am
doing seems pretty basic.

Thanks
