[vtkusers] VTK + Gtk

[Luca Pallozzi Lavorante]

Hello everybody,

I am planning the development of an application using VTK and GTk on 
Linux. I think I must use two separate threads as both VTK and Gtk own 
specific main loops.
I wonder which communication method between VTK  and  Gtk  is  better, 
as I  suppose  it is not possible  to exchange  data directly between 
them via global variables.
I think this is a crucial issue, as the Gtk GUI should be able to modify 
several visualization aspects controlled by VTK.
Can somebody help me understand which would be the most efficient way to 
do that? Is the multi-threaded approach right?

Thanks in advance
