QFileDialog single click behavior

[styson]

In Qt5.x QFileDialog behaves differently: on a single click it enters the directory and selecting files.
How can I get back the old behavior with double click?

What parts of QFileDialog do you use? On which OS?

Maybe it helps (are you on KDE?)

Edit:
Are you mixing the native OS style dialog and the Qt one?
