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
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
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,
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,
does not back up and follow other matching branches of
the widget tree.
