How to write a QString on several lines?

Do you have a better way to do that ?

QString str("I am a long long long"
              + QString("long long long")
              + QString("long QString开发者_运维百科") );

I don't like all this QString.

In C++ string literals are automatically concatenated when placed next to each other.

QString str("I am a long long long"
    "long long long"
    "long QString");

---

the QT way :

#include <QString>

QString myStr = QStringLiteral("");

Start typing, when you press return, he will auto add the " and open a new line starting with ".
