  I am creating a widget with XtCreateManagedWidget of class formWidgetClass,
and then trying to get PEX SI to use this window as its drawing surface.
Follows is a code summary:
      .
      .
      .
Pconnid_x_drawable connid;
Widget dform;

{X initilaization..blah blah blah}
{tform is the parent widget}

	dform = XtCreateManagedWidget("dform", formWidgetClass, tform,
					xarg,nxarg);

	connid.display = XtDisplay(dform);
	connid.drawable_id = XtWindow(dform);

	popen_phigs(PDEF_ERR_FILE, PDEF_MEM_SIZE);
	popen_ws(1, (char *)&connid, phigs_ws_type_x_drawable);
       .
       .
       .
I then procede to try to use the opened workstation. Code that produces
a pretty multi-colored 3D cube fails to display anything -- the screen
remains black. In another program I use the same structures, the same
view representation, but I dont use X toolkit. This program works fine.
Here is what I do:
	popen_phigs( PDEF_ERR_FILE, PDEF_MEM_SIZE );
	connid.display = display = XOpenDisplay( NULL );
	connid.drawable_id = XCreateSimpleWindow( display, blah blah blah);
      .
      .
      .
	popen_ws( 1, &connid, phigs_ws_type_x_drawable );
As I said, the 3D cube gets drawn w/o problems here. It seems to be the fact
that Im using the X toolkit...perhaps Im getting the values for
connid.display and connid.drawable_id incorrectly from the widget
superstructure? Has anyone ever dealt with this sort of thing before?
Can anyone suggest a reference or sample program that might provide insight?

Thanks
