QStringlist To QString

[momesana]

I am not sure I understand what you really intent to do, but If you want to change a QStringList into a QString, I guess join() is the operation you are looking for:
QString QStringList::join ( const QString & separator ) const
a QStringList is fundamantally different from a QString. It is actually a QList<QString> with some added convenience functions like split and join. So casting doesn't really makes sense. You can implement a cast operation for it on your own if you derive from QStringList and add a cast operator returning something like the joined string but I don't see what purpose that would be good for.

#include <QApplication>
#include <QtGui>
 
class StringList : public QStringList
{
        public:
                operator QString() const { return this->join(" ");  }
};
 
int main(int argc, char* argv[])
{
        QApplication(argc, argv);
        StringList sl;
        sl << "one" << "two" << "three";
        qDebug() << (QString)sl;
 
        return 0;
}

#include <QApplication>
#include <QtGui>

class StringList : public QStringList
{
        public:
                operator QString() const { return this->join(" ");  }
};

int main(int argc, char* argv[])
{
        QApplication(argc, argv);
        StringList sl;
        sl << "one" << "two" << "three";
        qDebug() << (QString)sl;

        return 0;
}
