XtCallAcceptFocus()													       XtCallAcceptFocus()

Name
  XtCallAcceptFocus - offer the input focus to a child widget.

Synopsis
  Boolean XtCallAcceptFocus(w, time)
	 Widget w;
	 Time *time;

Inputs
  w	    Specifies the widget; must be of class Core or any subclass thereof.

  time	    Specifies the X time of the event that is causing the accept focus.

Returns
  True if w took the input focus; False if w did not take the input focus.

Description
  XtCallAcceptFocus()  calls  the  specified widget's Core class accept_focus() method, passing it the specified widget and time, and True if
  the widget took the input focus, or False otherwise.	If the accept_focus() method is NULL, XtCallAcceptFocus() returns False.

Usage
  Generally, only widgets should call XtCallAcceptFocus(), and generally only on their descendants.

  Note that calling a widget's accept_focus() method does not automatically assign the input focus, and does not mean that  the  widget  will
  necessarily  take the input focus.  The accept_focus() method must decide whether or not to take the focus and then take it with XSetInput-
  Focus() or XtSetKeyboardFocus().

Background
  Widgets that need the input focus can call XSetInputFocus() explicitly, pursuant to the restrictions	of  the  Inter-Client  Communications
  Convention  Manual.	To  allow  outside  agents,  such  as  the parent, to cause a widget to take the input focus, every widget exports an
  accept_focus() method.  The widget returns a value indicating whether it actually took the focus or not, so that the parent  can  give  the
  focus  to  another widget.  Widgets that need to know when they lose the input focus must use the Xlib focus notification mechanism explic-
  itly (typically by specifying translations for FocusIn and FocusOut events).	Widget classes that never want the input focus should set the
  accept_focus() method to NULL.
