I've tried to follow Karen's suggestions but (I'm a beginner in
Performer integration with Windows management systems) I couldn't
produce any Performer graphics in the GlWidget: I get a segmentation
fault error when the application execute the first Performer graphics
output function, like pfuDownloadTexList with the 'show' option.
I think I'm doing the right Performer initialization stuff, but
I guess some GlwDrawingArea graphics configuration initialization calls
are missing in my application. I know (at least, I think so) which are
the calls to initialize it in order to render OpenGL graphics, but I don't
know the exact procedure to follow in order to get Performer output.
Any help? Thanks in advance.
