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 refer-
ence 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, XtNameTo-
Widget 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 fol-
low other matching branches of the widget tree.
The XtWindowToWidget function translates the specified
window and display pointer into the appropriate widget
