# Fileselectionbox
# ----------------------------------------------------------------------
# Implements a file selection box that allows 2 different styles. The
# default style is similar to the OSF/Motif standard XmFileselectionbox
# composite widget. The Fileselectionbox is composed of directory and file
# scrolled lists as well as filter and selection entry fields.
