    See the Xt specification, section 7.3, "Focusing Events on a Child"

Motif has its own knowledge on the keyboard focus. Thus moving focus
with Xt functions are prohibited. If you have Motif 1.1 or later, you
should have XmProcessTraversal() which lets you move the focus to your
desired place. If you have Motif 1.0, this functions was an internal
one, so *officially* you can't call it. Because Motif 1.1 is different
from Motif 1.0, migrating to Motif 1.1 is recommended.

The syntax and usage of XmProcessTraversal() [in Motif 1.1] is:

#include <Xm/Xm.h>
Boolean XmProcessTraversal(widget, direction)
Widget widget;
int    direction;

widget     Specifies the widget ID of the widget whose hierarchy is
           to be traversed
direction  Specifies the direction of traversal

If you give XmTRAVERSE_CURRENT to direction and your target widget
to widget parameter, the focus goes to your target.

Other direction includes: XmTRAVERSE_DOWN, XmTRAVERSE_HOME,
XmTRAVERSE_LEFT, XmTRAVERSE_NEXT, XmTRAVERSE_NEXT_TAB_GROUPm
XmTRAVERSE_PREV, XmTRAVERSE_PREV_TAB_GROUP, XmTRAVERSE_RIGHT,
and XmTRAVERSE_UP.
