XtNameToWidget(3Xt)         X Version 11(Release 3)         XtNameToWidget(3Xt)


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 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.
