I am trying to port a simulation package from Inventor to Performer. I
am having trouble making a pfPipeWindow draw into a Widget. I have a
window with several widgets, and in some of them I am trying to put a
pfPipeWindow. I create the pfPipeWindow and the widget, and then call
pfPipeWindow::setWSWindow(). When I call pfPipeWindow::open() a whole
new motif window is created outside of my origonal window. How do I make
Performer render to just one area of a window?

Here is the code I am using:

/* pfPipeWindow created here
...
*/

// I need a void** to pass to pfChooseFBConfigData()
int* foo = (int*)pfMalloc( sizeof(int), pfGetSharedArena() );
// I create an OpenGL rendering widget
windowWidget = XtVaCreateManagedWidget( name,
                        glwMDrawingAreaWidgetClass, parentWidget,
                        GLwNvisualInfo,
                        pfChooseFBConfigData( (void**)&foo,
                                XtDisplay(parentWidget), -1, NULL,
                                pfGetSharedArena() ), NULL );
_win->setWSDrawable( NULL, XtWindow( windowWidget ) );
_win->setWSWindow( NULL, XtWindow( parentWidget ) );

/* pfPipeWindow::open() called later
...
*/

The widget is always black, and the seperate pfPipeWindow draws
properly. Its like I never called setWSWindow().

Does anyone know what's going wrong?
