Updating the value takes immediately, as it did in 2017.1 and prior.
Additionally, passing —download-dir on the command-line is detected
and handled specially; the UI option is disabled, and no changes are
made to the value passed in. (The launcher does not override the value
with any value it has saved)
Change fgcommand to take an optional property tree root element.
This fixes the animation bindings to use the defined property tree root - to support multiplayer (or other) model that can bind to the correct part of the property tree.
Requires a corresponding fix in sg to allow the command methods to take an optional root parameter.
What this means is that when inside someone else's multiplayer model (e.g. backseat, or co-pilot), the multipalyer (AI) model will correctly modify properties inside the correct part of the property tree inside (/ai), rather than modifying the properties inside the same part of the tree as the non-ai model.
This means that a properly setup model will operate within it's own space in the property tree; and permit more generic multiplayer code to be written.
This is probably responsible for some of the pollution of the root property tree with MP aircraft properties.
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).
When the user specified an MP server without providing a port, the
launcher would pass a malformed command line, leading the the simulator
bailing out.
(Should go to the release branch)
Add an additional visibility flag to the menubar implementations,
conditional on whether or not the menubar overlaps the window content.
(I.e for PUI but not Cocoa). This flag is linked to a new property
/sim/menubar/overlap-hide, which the renderer drives off the splash-
screen visibility.
On Windows, use:
- QtFileDialog if FG was built with Qt support;
- PUIFileDialog otherwise.
Behavior on other platforms is unchanged. This change is motivated by
the fact that some Windows users have reported[1][2] weird,
non-deterministic behavior of WindowsFileDialog and unfortunately, no
one seems to be willing and able to fix the problem. The Qt
implementation comes for free and should be quite robust. Of course, if
someone wants to maintain the WindowsFileDialog class again, the change
can be reverted.
See discussion at [3].

We now show paths in ‘view command line’ and set them through the
standard mechanism. Re-ordering the paths also notifies the rest of
the system correctly.
- Rename fatalMessageBox() to fatalMessageBoxWithoutExit(). This should
prevent the kind of bug that prompted this set of changes: someone
calling fatalMessageBox(), assuming the program would stop at that
point, whereas in reality it did not.
- Add new function fatalMessageBoxThenExit(). This is not vital of
course, but allows one to spare one line here and there and to apply
the DRY principle for such fatal exits.
- Replace every existing call to fatalMessageBox() with one or the other
of the two new functions. Improve formatting along the way. This
fixes a few bugs of the kind explained above.
This reverts commit 9e6a3ebc6b ("Make
fatalMessageBox() end with std::abort() and declare it [[noreturn]]").
After reflexion, it seems better to let fatalMessageBox() return,
because there is existing code that appears to be relying on this aspect
to do some work after having called fatalMessageBox() (cf. main() in
bootstrap.cxx). Also, the way of exiting from fatalMessageBox() after
commit 9e6a3ebc6b (std::abort()) was probably too brutal for a
controlled exit---as opposed to a terminate handler.
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/>).
