XtNameToWidget(3Xt)
X11R6
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
  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.
