XtNameToWidget(3Xt)                  BSD                   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.
