# Extfileselectiondialog
# ----------------------------------------------------------------------
# Implements a file selection dialog that is a slightly extended version
# of the OSF/Motif standard 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.
