XtSetKeyboardFocus(3Xt)		 XT FUNCTIONS	      XtSetKeyboardFocus(3Xt)



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 previ-
		 ously 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
       widget W in one of three ways:

       ·    W has the X input focus.

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

       ·    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.	 Sim-
       ilarly, when W loses the X input focus or the keyboard focus for one
       of its ancestors, a FocusOut event is generated for descendant if
       FocusNotify events have been selected by the descendant.
