Random number or random string with qt

  • Hi some way to get a random number or string with Qt. I want that these elements dont repeat to get totally random strings or numbers. Any idea it's good received thx.

    There is big difference between a random string and just a random number?
    Anyway, fast way is just

    QString MyNum;
    int rVal=rand()%1000;
    MyNum = QString::number( rVal ) ;

    If you want truly unique ID, you can use

    So solution also depends on how many you will generate and
    how unique it must be. Also over time.
