Hello Performer-Teams,
I'm a student of aerospace engineering and until now I'm programming
OpenGl applications in conjunction with Motif. Now I will start to use
Performer. The problem I have is to use Performer in conjunction with
Motif, but the application will be build by RapidApp!!!

I did the following steps:
- create an application with RapidApp,
- include an GL-DrawingArea and various buttons (all different widgets),
- last I insert all needed commands to allow OpenGl-drawings,

Now I want to take this DrawingArea to use Performer. In the existing
Demo-program "motif.C" the main() is given by Performer an after it's
initialisation the Motif-part is started in a forked process. In
contrast my main process must be in my Motif-program and from this I
will invoke several Performer-programs. My questions
are:
Is it generally possible to use an existing window with a glwidget
(created with Motif) for Performer, especially this created DrawingArea?
If it is possible, how can I tell it the Performer, that this window and
this Area is to use? Until now I can only invoke the Performer at what
it open its own window behind my primary Motif-window.
It would be glad if You would answer my questions and could help a
beginner to understand the principle of working with Performer in
combination with Motif.

With best regards
                        Thomas Ludwig.
