QFileDialog issue

ivanicy

Hello!

I am using a QFileDialog to obtain a folder path. I don't know why this process take a lot of time. (about a minute). I don't know if is a QFileDialog issue of Qt or something like this. This is my code:

QString sDirectory;

sDirectory = QFileDialog::getExistingDirectory(this, tr("Open directory"), 
QStandardPaths::writableLocation(QStandardPaths::DocumentsLocation), 
QFileDialog::ShowDirsOnly | QFileDialog::DontResolveSymlinks);

ui->labelCalibrationPath->setText(sDirectory);

As you can see, this is a very simple code.

Any idea of what is happening here?

Thank you very much!!

Do you have had any network shares ?

I've tried with an empty project and it works fine. So, it could be that you say but I don't know what do you mean with network shares

@ivanicy If you have any network shares (network drives) it can take long for the OS to look up them.

You may also be interested in reading through https://forum.qt.io/topic/95305/checking-run-time-characteristics-for-qfiledialog-getopenfilename. That is discussing a user experiencing long delays with a file dialog, though in a different situation.

You might follow some of my suggestions there. You might also try passing DontUseNativeDialog and see whether that affects the situation (I find the docs confusing as to whether getExistingDirectory() respects this flag under Windows, but you could try.)
