Extra Double Quotes ("") retrieves from objectName.

Hi,

I'm beginner to the Qt and while studying the Qt course material I got a problem.

I have 3 files.

valueobject.h

@#ifndef VALUEOBJECT_H
#define VALUEOBJECT_H

#include <QObject>

class ValueObject : public QObject
{
Q_OBJECT

public:
explicit ValueObject(QObject *parent = 0);
virtual ~ValueObject();

};

#endif // VALUEOBJECT_H@

valueobject.cpp

@#include "valueobject.h"
#include <QDebug>

ValueObject::ValueObject(QObject *parent) :
QObject(parent)
{
qDebug() << "ValueObject constructed";
}

ValueObject::~ValueObject()
{
qDebug() << "ValueObject" << this->objectName() << "destructed";
}@

3.main.cpp

#include "valueobject.h"

@#include <QDebug>
#include <QFile>

int main(int argc, char *argv[])
{
ValueObject o;
o.setObjectName("root");

return 0;

}@

When I run the program I got the result as

ValueObject constructed
ValueObject "root" destructed

My problem is how extra "" appears in both sides of word 'root'?

I also tried

@QString root ="root"
o.setObjectName(root);@

but result is same.

Thanks in advance.

thats how QDebug handles QStrings.
To get it without the double quotes you can do the following:
@qDebug() << "ValueObject" << this->objectName().toLatin1().data() << "destructed";
