You need to connect your slot to the fileChanged() signal instead of directoryChanged() if you are more interested in the file names.

connect(&myFileSystemWatcher, SIGNAL(fileChanged(const QString&)), SLOT(handleFileChanged(const QString&)));

Then, you can just use the slot argument as desired. Here, I am just printing it out to stdout:

void handleFileChanged(const QString &path)
{
    qDebug() << path;
}

Please see the documentation for further details:

void QFileSystemWatcher::fileChanged(const QString & path) [signal]

This signal is emitted when the file at the specified path is modified, renamed or removed from disk.

Not sure how much you are familiar with the Qt signal/slot system, but if not enough, please go through this, too:
