   does anybody know how to excplicitly set the focuus to a widget without
   sending XEvents or calling XtSetKeyboardFocus (which doesn't work) ?

	   THANKS in advance (:->

XtSetKeyboardFocus() _DOES_ work.. you are trying to make it do
something it is not supposed to.  XtSetKeyboardFocus() allows X events
sent to a hierarchy of widgets to be forwarded to a single widget (for
example, if your mouse is in a dialog box you want key events to go to
the text widget, even if the mouse happens to be over a pushbutton.)

I don't know of an Xt function that explicity sets keyboard focus.
Use XSetInputFocus().  For example:

XSetInputFocus(XtDisplay(TopLevelWidget), XtWindow(widget),
               RevertToParent, CurrentTime);

TopLevelWidget is the widget returned by XtInitialize.  widget is the
widget you want keyboard focus set to.  The last two arguments are
constants.. type "man XSetInputFocus" for more details.

NOTE:  Don't use this function call!!!  The only program that I've
seen that has a good reason to call XSetInputFocus is xscreensaver,
and that is for an unusual reason.  It is generally very rude to force
focus to a certain window.
