Embedding an Xt Widget into a GTK Window

["Graham Dawes" <graham ffa co uk>]

Hi,

I'm very new to GTK so you'll have to execuse me if this is a stupid
question.

Is it possible mix the use of Xt and GTK in the same application?   I'm
trying to write an application that use GTK  for it's GUIs and uses a
closed source Open Inventor implementation to perform rendering (via an
Xt widget). Is this even feasible?

Thanks
