* See https://github.com/Martchus/syncthingtray/issues/59
* QCoreApplication::aboutToQuit() does not work reliably but terminating
only at the end of the session is a common use-case for the tray
application. So workaround the problem by saving the settings
immediately.
* The plasmoid already does this anyways.
Map context menu coordinates to top-level widget if the top-level
widget is a QMenu. Otherwise the context menu is not displayed at
the right position. Not sure why this workaround is required.
The check for QMenu is required. Otherwise the "windowed" mode
enabled via --windowed CLI argument would not work anymore. In
this mode the top-level window is a regular window.
Adding the window flags Qt::Sheet or Qt::Dialog to the QMenu
would help as well but that prevents closing the menu (see
https://github.com/Martchus/syncthingtray/issues/41).
This is useful because sometimes the background color of the system
tray is dark but the overall system UI still uses a light theme.
For the Plasmoid this should never be the case, though. Hence the
extra settings are not available there.
* Take the time the launcher is active into account (in the same
way as it is done for the systemd service)
* Fix case when systemd service would be relevant but configured
to consider the launcher status
* Rely not only on the FolderErrors event
* Request pull errors when opening the dialog
* Use "pullErrors" from FolderSummary
* Move code for directory error dialog into
its own class
This should fix that sometimes obsolete errors
were still displayed or actually present errors
missing.
Add new SyncthingLauncher class which lauches Syncthing
under the hood via external SyncthingProcess or using
libsyncthing.
Note: Launching via libsyncthing is still experimental.
