NAME

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

SYNOPSIS

       Widget XtNameToWidget(reference, names);
	       Widget reference;
	       String names;

       Widget XtWindowToWidget(display, window)
	       Display *display;
	       Window window;

ARGUMENTS

       Specifies the display on which the window is defined.  Specifies the fully qualified name of the desired widget.  Specifies the widget from
       which the search is to start.  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  ref-
       erence  (or  a  normal child if reference is a subclass of compositeWidgetClass). 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 specified 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 display pointer into the appropriate widget instance.
