Instead of tying the QFileSystemWatcher to the GameList and updating in
the UI thread, this change moves it to the worker thread. Since it gets
deleted and recreated as part of the worker thread, this prevents it from
ever getting used from multiple threads (which is why it was originally
done on the UI thread)
Corrects a few issues with regards to Doxygen documentation, for example:
- Incorrect parameter referencing.
- Missing @param tags.
- Typos in @param tags.
and a few minor other issues.
Fixes#1115.
Also improves the performances of DiskArchive’s directory
implementation a lot, simply by not going through the entire tree
instead of just listing the first level files.
Thanks to JayRoxFox for rebasing this on current master!
