[vtkusers] invalid drawable ; Mac OSX Mavericks and vtk 6.1

[Kim Rosenbohm]

 Hi.

I do this (using Windows and Qt) by deriving from QVTKWidget2,

overwriting the ShowEvent() in that class and sending a signal from
that event function.
Then, In the slot that is called, do your setup,
e.g. AddRenderer and initializing the interactors...

Hope that
helps,

Kim

The other two bullets on that page are to no help either I am afraid.
