XtNameToWidget(3)                               XT FUNCTIONS                               XtNameToWidget(3)



NAME
       XtNameToWidget, XtWindowToWidget - translating strings to widgets or widgets to windows

SYNTAX
       Widget XtNameToWidget(Widget reference, String names);

       Widget XtWindowToWidget(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 com-positeWidgetClass). compositeWidgetClass).
       positeWidgetClass).  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 compo-nent, component,
       nent, 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 appropri-ate appropriate
       ate widget instance.
