NAME
       XtNameToWidget, XtWindowToWidget - translating strings to widgets or
       widgets to windows

SYNTAX
       Widget XtNameToWidget(Widget reference, String names);

       Widget XtWindowToWidget(Display *display, Window window);

ARGUMENTS
       display	 Specifies the display on which the window is defined.

       names	 Specifies the fully qualified name of the desired widget.

       reference Specifies the widget from which the search is to start.

       window	 Specify the window for which you want the widget.

DESCRIPTION
       The XtNameToWidget function looks for a widget whose name is the first
       component in the specified names and that is a pop-up child of refer-
       ence (or a normal child if reference is a subclass of compositeWidget-
       Class).	It then uses that widget as the new reference and repeats the
       search after deleting the first component from the specified names.
       If it cannot find the specified widget, XtNameToWidget returns NULL.

       Note that the names argument contains the name of a widget with
       respect to the specified reference widget and can contain more than
       one widget name (separated by periods) for widgets that are not direct
       children of the specified reference widget.

       If more than one child of the reference widget matches the name,
       XtNameToWidget can return any of the children.  The Intrinsics do not
       require that all children of a widget have unique names.	 If the spec-
       ified names contain more than one component and if more than one child
       matches the first component, XtNameToWidget can return NULL if the
       single branch that it follows does not contain the named widget.	 That
       is, XtNameToWidget does not back up and follow other matching branches
       of the widget tree.

       The XtWindowToWidget function translates the specified window and dis-
       play pointer into the appropriate widget instance.
