When adding a scenery path in the built-in launcher, accept folders
containing any of the new directories populated by osm2city. Also try to
improve the message that is displayed when the sanity check conditions
for the added scenery path aren't met (cf. discussion around
<https://sourceforge.net/p/flightgear/mailman/message/35716946/>).
For unknown reasons this seems to alleviate the word-wrap / min-height
bug on Windows. Committing so we can test and verify this is really
the case before the next release.
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)
- Add an optional argument to flightgear::initApp(): doInitQSettings.
This argument defaults to true, preserving initApp()'s behavior in
this respect. If this argument is set to false, FGGlobals doesn't have
to be initialized.
- New function flightgear::initQSettings(), called by
flightgear::initApp() when its 'doInitQSettings' argument is true.
This allows initializing the QSettings exactly when it is needed.
- New function flightgear::checkKeyboardModifiersForSettingFGRoot().
The code it contains used to be run from initApp(), which is
undesirable because:
1) initApp() is not only called at FG initialization (fgMainInit()),
but also from QtMessageBox(), from QtFileDialog::exec() and twice
from Options::setupRoot(). However, checking the Alt and Shift
modifiers to set 'fg-root' in QSettings to the special value
"!ask" only makes sense in fgMainInit(), not in these other
places.
2) This code relies on the QSettings to be set up, and therefore on
FGGlobals. Thus, freeing initApp() of its dependency on FGGlobals
requires splitting this keyboard modifiers checking code out of
initApp().
Instead of the two vectors we manually composed, used a single unified
vector of structs to store delegate information in the model. This
simplifies the logic for tracking the active variant (and in the future,
thumbnail).
Move the existing aircraft history to a more obvious place, and follow
the same pattern for the complete location history. This makes restoring
a previously used configuration much simpler.
