# Extfileselectionbox
# ----------------------------------------------------------------------
# Implements a file selection box that is a slightly extended version
# of the OSF/Motif standard XmExtfileselectionbox composite widget.
# The Extfileselectionbox differs from the Motif standard in that the
# filter and selection fields are comboboxes and the files and directory
# lists are in a paned window.
