NAME

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

SYNTAX

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

Widget XtWindowToWidget(display, window)
      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 reference (or a normal child if reference is
     a subclass of compositeWidgetClass).  It then uses that wid-
     get as the new reference and repeats the search after delet-
     ing 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 con-
     tain more than one widget name (separated by periods) for
     widgets that are not direct children of the specified refer-
     ence 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 com-
     ponent, 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.
