QStringlist To QString

HI All
CAn any body tell me how to change QStringlist object to QString type.
my code is QStringList list1 = str.split(".");
i need to change list1 to Qstring type.
I tried like this reinterpret_cast<QString>(list1). but giving error.
THank you all.

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.

Code:

---

#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;
}

A QStringList strlist is a list of QString .... so strlist[0] is a QString.

Hi,

Here you know that your QStringList will be only a single QString when you split it because you know that only there is one QString, I'm right?

So,

Code:

---

QStringList list1 = str.split(".");
QString myString = list1.at(0);  //You know that only is there one QString in the list

Here is the solution :

Code:

---

QStringList strList;
strList << "bird" << "tree" << "water" ;
 
QString str = strList.join("");  // str = "birdtreewater";
str = strList.join(",");  // str = "bird,tree,water";

Nice. I am sure that after 6 1/2 years of waiting since 2007, phillip_Qt was overjoyed to get your answer. ;)
