[vtk-developers] QVTKWidget

[Clinton Stimpson]

What about the examples in VTK/Examples/GUI/Qt?
I've seen others with plugin crashes, due to incorrect setup.
They happened because of incompatible dependent libraries were being found
instead of the ones that were used to build the plugin.  For example, the
wrong Qt library or VTK libraries were being found in LD_LIBRARY_PATH.
