# 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.
|
