Representative:
Display *dsp(XOpenDisplay(NULL));
XVisualInfo *vi = glXChooseVisual(dsp, DefaultScreen(dsp), visBuf));
GLXContext ctxt = glXCreateContext(dsp, vi, None, True));
XSetWindowAttributes attr;
Window win = XCreateWindow(dsp, RootWindow(dsp, vi->screen), 0, 0,
1280, 1024,
0, vi->depth, InputOutput, vi->visual,
CWBorderPixel|CWColormap|CWEventMask, &attr);
XSetStandardProperties(dsp, win, "3D", "3D", None, argv, argc, NULL);
XMapWindow(dsp, win0);
The above code is user code so that they do their own window management
(placement, size, event handling, etc.).
I'm porting an app over from Performer that plugged XWindows in as so:
pwin->setWinType (PFPWIN_TYPE_X);
pwin->setWSWindow (dsp, win);
pwin->setWSDrawable(dsp, win);
pwin->setGLCxt (ctxt);
So, if I can emulate this behavior I'm good to go.
If not, I'd have OSG create my windows sharing a single GLXContext
amongst them internally.
But, I don't know how to share that single GLXContext internally. I
suspect it's very simple to do.
I'd also have to expose window management to my end users.
Unfortunately, I don't have a good handle on the scope of what to
expose.
The GLUT windowing interface comes to mind as generic, robust, and
elligant.

What are you using for creating and managing your windows at present?
Do you do the X11 windowing yourself?
