[vtkusers] imageViewer size within QVTKWidget

[Nick Patterson]

I similarly see this problem and and have not yet found the resolution. Information at the bottom of the page associated with:-

http://www.vtk.org/Wiki/VTK/OpenGL_Errors

highlights this Mac specific problem, but is next to useless in actually explaining the problem since they don’t indicate exactly what is meant by “restructure your code”.

If you find a solution, please let me know. 

Nick.
