     I'm sure this has been discussed here before but I can't seem to find
     any record of it.  Does anyone have a working example of setting the
     application icon from within the application?

In Motif, create a single plane bitmap of the proper size (usually 48x48,
but technically one should call XGetIconSizes to determine the sizes which
the window manager wants) and then set the XmNiconPixmap resource of your
application's shell widget.

In my code this looks something like:

creating bitmap:

    Display*	    display;
    Drawable        rootWin;
    unsigned int    width;
    unsigned int    height;
    char*	    iconBits;   // the output from 'bitmap'
    Pixmap	    iconPixmap;

    iconPixmap = XCreateBitmapFromData( display, rootWin,
                                        iconBits, width, height);

creating shell widget:

    XtSetArg( argList[i], XmNiconPixmap, iconPixmap);           i++;

    appShell = XtAppCreateShell( (String) appName, (String) appClass,
                                  applicationShellWidgetClass,
                                  display, argList, i);

Sorry that this isn't a working example, but I had to cut these code
fragments out of a larger C++ program and I don't have time to paste them
all together.
