[vtk-developers] Linking a VTK viewer in MFC Application

Hello Sridhar,
When you start your application it first creates the window elements on the screen. These window elements must be created in the proper order. And the link between the VTK viewer and the MFC window also has to be established at the proper moment during the creation process (so not at the moment when you press the button). The example of David Gobbi shows exactly where you should make the link. Also his way of linking the views is very nice. So maybe it is better if you copy his example.
regards,
Leo.

> I have tried to link several controls with a VTK viewer, but until now I had no success (if somebody else knows how to do this, please post it). So I link the VTK Viewer to the document view (see code below). I call this function in the Create function of the document view. Allthough I used a multiple document interface, I think it will also work for your single document viewS.
