XtNameToWidget(3Xt)		XT FUNCTIONS		  XtNameToWidget(3Xt)



NAME
  XtNameToWidget, XtWindowToWidget - translating strings to widgets or wid-
  gets 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 com-
  ponent 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 speci-
  fied 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, XtNameTo-
  Widget 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 window and display
  pointer into the appropriate widget instance.
