    Yes, sure you can. You can ask the user for anything you like.

    Wow I'm suprised, I didn't think you could. Is it an in-built function in QDialog or is there some path or something I have to specify?

    facepalm.


    .............
    If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

    You can ask the user to provide anything you want. This has precisely nothing to do with what your code does with the provided information.

    There is no auto-magic, obtain root login credentials, change the process effective uid to zero, and do stuff dialog. You have to code everything you want done with the user's input.

    That's what I thought but I enquired simply because QFileDialog is able to identify paths using users' default directory auto-magically. I understand to do something like this you would probably have to have root privileges set on the application anyway.

    No, you don't need superuser privileges to determine users' home paths.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
