Description

QFileSystemModel relies on QFileInfoGatherer for file system watching.

QFileInfoGatherer::setWatching(bool v) can only disable watching, not enable it. There is just no code to do it in this member function:

void QFileInfoGatherer::setWatching(bool v)
{
#if QT_CONFIG(filesystemwatcher)
    QMutexLocker locker(&mutex);
    if (v != m_watching) {
        if (!v) {
            delete m_watcher;
            m_watcher = nullptr;
        }
        m_watching = v;
    }
#else
    Q_UNUSED(v);
#endif
}
