NAME

       XtGetKeyboardFocusWidget - extension event handling

SYNTAX

ARGUMENTS

       widget	 Specifies the widget for this event handler.  Must be of class Core or any subclass thereof.

DESCRIPTION

       XtGetKeyboardFocusWidget function returns the widget that would be the end result of keyboard event forwarding for a keyboard event for the
       specified widget.

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 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 widget 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 descendant 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
       FocusNotify events have been selected by the descendant.
