line edit only numbers with int64



  • hello
    i want make a line edit only accept numbers , so i used :

    ui->barcode->setValidator(new QIntValidator(0, 999999999999, this));
    

    but i keep getting convery from int64 to int 32
    so how i can use int64 ? or use unsinged int

    You can't use int64 or unsigned int with QIntValidator. You'll need to create your own validator for that by subclassing QValidator and implementing fixup() and validate().
