# 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.
