15# Editor dialog for approach callouts.
16#
17# The dialog consists of an aircraft type selector box at the top, and a table
18# with two buttons below it. The table contains the callout files with the
19# corresponding altitudes, and is sorted according to the altitude. When a new
20# file is added, the program finds out a new altitude for it. If the file's
21# name contains numbers that are not used as altitudes yet, the most suitable
22# of those numbers will be used. Otherwise a 'usual' altitude is searched for,
23# in the direction according to the sort order, and if that fails too, the
24# altitudes are tried one-by-one. See the
25# \ref ApproachCalloutsEditor._getNewAltitude function for more details.
