As spotted by Thorsten, reduce user annoyance by asking about FGData
when the built-in data is acceptable. (Advanced users can use the
launcher or other options to change FGdata as normal).
Requires FGData commit: 0565eaab10a5d466cd485766b17d1870936a0a57
(which actually renames the file).
Also disables the preferences-load command since I don’t believe it
would actually be safe to reload the defaults without doing a simulator
reset (aircraft -set.xml values would be overwritten, for example)
- Only clear the OSG ‘pose as standalone’ flag when we really show
a dialog, as opposed to when we /might/ show.
Tested:
- Qt build using launcher
- No Qt build
- Qt build but launcher not requested
- add a button to the main dialog, explaining how to adjust the
fg-root path via the GUI
- tweak the GUI flow to support explicitly changing the path even
when the default path is acceptable.
