concatenate two values

hi all,

please tell me how to make concatenate of two different datatypes

Qstring str="4";
unsigned long lg=100001;

now i want to make the value as lg= 4100001 .(i.e.,"4"+100001)

Thanks,

Have a look at the QString documentation, you can convert unsigned long to QString and then concatenate.

Hi;

try use the class QVariant.

Or something like this:

Code:

---

str.append(QString("%1").arg(lg));

---

Code:

---

QString str="4";
    unsigned long lg=100001;
 
 
    str += QString("%1").arg(lg);
    qDebug() << str;
    lg=str.toLong();
    qDebug()<< lg;
