# FileSelector class (derived from Dialog class).
#
# SYNOPSIS: FileSelector.new(<callback> [, <oper> [, <dir> [, <file> [, <hidden>]]])
# SYNOPSIS: FileSelector.new(<callback> [, <title> [, <button> [, <dir> [, <file> [, <dotfiles>]]]])
#
# callback ... callback function that gets return value as cmdarg().getValue()
# oper ... string that describes purpose (put on the "OK" button)
# title ... dialog title
# button ... button text ("OK" by default, but should say "Save", "Load", etc.))
# dir ... starting dir ($FG_ROOT if unset)
# file ... pre-selected default file name
# hidden ... flag that decids whether UNIX dotfiles should be shown (1) or not (0)
# dotfiles ... flag that decids whether UNIX dotfiles should be shown (1) or not (0)
#
# EXAMPLE:
#
# var report = func { print("file ", cmdarg().getValue(), " selected") }
# var selector = gui.FileSelector.new(report, "Save Flight", "/tmp", "flight.sav");
# var selector = gui.FileSelector.new(report, "Save Flight", "Save", "/tmp", "flight.sav");
# selector.open(); # see the Dialog class for other methods
