QFileSystemModel doesn't emit fileRenamed signal

[yeakub]

I am trying to watch the changes in a directory using QFileSystemModel. Whenever I rename a file in the root path, only the directoryLoaded() signal is emitted. I want the fileRenamed() signal to be emitted so that I know which file is renamed to a new name. Here is my code:

    model = new QFileSystemModel;
    model->setRootPath("C:/test/");
    QObject::connect(model, SIGNAL(fileRenamed(const QString&, const QString&, const QString&)), this, SLOT(updateRename()));
    QObject::connect(model, SIGNAL(directoryLoaded(const QString&)), this, SLOT(loadDir()));

@yeakub said in QFileSystemModel doesn't emit fileRenamed signal:

QFileSystemModel only sends the signal if the file is renamed inside the model.

Well, yes, naturally.

If you are wanting to track external changes you are supposed to use QFileSystemWatcher.

@yeakub
To confirm:

• You are renaming file C:\test\fileold to C:\test\filenew?
• You do not get fileRenamed signal?
• But instead you do get a directoryLoaded signal? Parameter C:/test/?

Yes, correct. I renamed the file manually. I am guessing that the QFileSystemModel only sends the signal if the file is renamed inside the model. But I couldn't find any documentation on that.
