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
