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)
* citra-qt: game list search function
* Empty search field during game list refresh
* Code improvements
* Code formatting
* Autofocus search field
* JayFoxRox's recommendations
* lioncash's review
* Added a refresh game directory option to the file menu
* Make the game list watcher recursive and have it start watching from the initial load
* Rework game list watcher to be thread safe
* Fix code style issues
If the control was ever passed an explicit parent, a potential memory leak
would happen, as the game list wouldn't be freed.
However, in our case, the game list was placed within a layout, which
automatically performs reparenting, avoiding this issue.
ForeachDirectoryEntry didn't actually do anything with the `recursive`
parameter, and the corresponding callback parameter was shadowing the
actual recursion counters in the user functions.
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!
ScanDirectoryTreeAndCallback, before this change, coupled error/return
codes and actual return values (number of entries found). This caused
confusion and difficulty interpreting the precise way the function
worked.
Supersedes, and closes#1255.
