[vtkusers] Multiple interactors in one renderwindow.

[Maurice van de Rijzen]

Dear all.
I've a tkRenderWindow subdivided into four subwindows.
To each subwindow I attach a renderer.
For one of the subwindows I want to use one of the interactorstyles of 
vtk and for the rest maybe another interactor-style ( I don't know yet).
Now is my problem the following.
Afaik, the vtkRenderWindowInteractor is coupled to a renderwindow and 
not to a single renderer.
Is it however somehow possible to select for each renderer another 
interactor.
Is there maybe some (easy) way to determine which rdendeer invoked the 
interaction.
And if so, how can I using this knowledge of the renderer select for 
each renderer another interactor.

Thanks,
Maurice
