You are doing something wrong. The top widget must have its
allow_shell_resize attribute set to TRUE (it is FALSE by default). Add this
after your XtInitialize:

	XtSetArg(args[0], XtNallowShellResize, TRUE);
	XtSetValues (toplevel, args, 1);

This will allow the top level widget to resize itself when necessary. The
toolkit seems to default all resize attributes to FALSE. I ran into the same
thing with a label on a form -- when I changed the label text, the label did
not resize until I set its resizable attribute (see the Athena Widgets doc,
page 30) to TRUE.
