XtSetKeyboardFocus(3)		 XT FUNCTIONS		 XtSetKeyboardFocus(3)

NAME
       XtSetKeyboardFocus - focus events on a child widget

SYNTAX
       XtSetKeyboardFocus(Widget subtree, Widget descendant);

ARGUMENTS
       subtree	 Specifies either the widget in	the subtree structure which is
		 to receive the	keyboard event,	or None.  Note that it is not
		 an error to specify None when no input	focus was previously
		 set.

       descendant
		 Specifies the widget for which	the keyboard focus is to be
		 set.

DESCRIPTION
       If a future KeyPress or KeyRelease event	occurs within the specified
       subtree,	XtSetKeyboardFocus causes XtDispatchEvent to remap and send
       the event to the	specified descendant widget.

       When there is no	modal cascade, keyboard	events can occur within	a wid-
       get W in	one of three ways:

       o    W has the X	input focus.

       o    W has the keyboard focus of	one of its ancestors, and the event
	    occurs within the ancestor or one of the ancestor's	descendants.

       o    No ancestor	of W has a descendant within the keyboard focus, and
	    the	pointer	is within W.

       When there is a modal cascade, a	widget W receives keyboard events if
       an ancestor of W	is in the active subset	of the modal cascade and one
       or more of the previous conditions is True.

       When subtree or one of its descendants acquires the X input focus or
       the pointer moves into the subtree such that keyboard events would now
       be delivered to subtree,	a FocusIn event	is generated for the descen-
       dant if FocusNotify events have been selected by	the descendant.	 Simi-
       larly, when W loses the X input focus or	the keyboard focus for one of
       its ancestors, a	FocusOut event is generated for	descendant if FocusNo-
       tify events have	been selected by the descendant.
