Question

I have:

QFileDialog file_dialog;
    file_dialog.setFileMode(QFileDialog::Directory);

    QStringList selected_directory; 
    selected_directory << file_dialog.getExistingDirectory();  

But I cannot see any files. Is there any way to see them yet being able to select just directory?

Answer 1

Check the documentation.

When you are calling the getExistingDirectory the ShowDirsOnly flag is set

 QString dir = QFileDialog::getExistingDirectory(this, tr("Open Directory"),
                                                 "/home",
                                                 QFileDialog::ShowDirsOnly
                                                 | QFileDialog::DontResolveSymlinks);

Use instead the following:

QFileDialog dialog(this);
dialog.setFileMode(QFileDialog::Directory);
QStringList dirNames;
if (dialog.exec())
    dirNames = dialog.selectedFiles();

The selected directories can be retrieved from the dirNames string list.
