if I have a dialog box with some checkboxes, some ratiobuttons etc, and I select some of them after I close this dialog and open it again all checkboxes are unchecked. What is the best way to store the state of this dialog box?

If you want to keep the state while the app is running – simply keep the dialog around and show/hide it as necessary.
If you need to keep state for next time the app is run then you need to store the individual settings separately (see QSettings) – this makes sense if say an update of your app add new settings.
