XtNameToWidget(3Xt)                           XtNameToWidget(3Xt)



NAME
     XtNameToWidget,  XtWidgetToWindow  -  translate  strings  to
     widgets and widgets to windows

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

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

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
     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 names 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 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.

     The XtWindowToWidget function translates the specified win-
     dow and display pointer into the appropriate widget in-
     stance.

   Arguments
     These functions accept the following arguments:

     display Specifies the display on which the window is de-
             fined.

     names   Specifies the fully qualified name of the desired
             widget.
