关键代码

void CPanel::showAllFilesFromCurrentFolderAndBelow()
{
	_currentDisplayMode = AllObjectsMode;
	_watcher.setPathToWatch({});

	_workerThreadPool.enqueue([this]() {
		std::unique_lock<std::recursive_mutex> locker(_fileListAndCurrentDirMutex);
		const QString path = _currentDirObject.fullAbsolutePath();

		_items.clear();

		//locker.unlock();
		// TODO: synchronization and lock-ups
		const bool showHiddenFiles = CSettings().value(KEY_INTERFACE_SHOW_HIDDEN_FILES, true).toBool();
		scanDirectory(CFileSystemObject(path), [showHiddenFiles, this](const CFileSystemObject& item) {
			if (item.isFile() && item.exists() && (showHiddenFiles || !item.isHidden()))
				_items[item.hash()] = item;
		});
		//locker.lock();

		sendContentsChangedNotification(refreshCauseOther);
	});
}


// Calculates directory size, stores it in the corresponding CFileSystemObject and sends data change notification
void CPanel::displayDirSize(qulonglong dirHash)
{
	_workerThreadPool.enqueue([this, dirHash] {
		std::unique_lock<std::recursive_mutex> locker(_fileListAndCurrentDirMutex);

		auto it = _items.find(dirHash);
		assert_and_return_r(it != _items.end(), );

		if (it->second.isDir())
		{
			locker.unlock(); // Without this .unlock() the UI thread will get blocked very easily
			const FilesystemObjectsStatistics stats = calculateStatistics(std::vector<qulonglong>(1, dirHash));
			locker.lock();
			// Since we unlocked the mutex, the item we were working on may well be out of the _items list by now
			// So we find it again and see if it's still there
			it = _items.find(dirHash);
			if (it == _items.end())
				return;

			it->second.setDirSize(stats.occupiedSpace);
			sendContentsChangedNotification(refreshCauseOther);
		}
	});
}
