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.

    1. valueobject.h

    @#ifndef VALUEOBJECT_H
    #define VALUEOBJECT_H

    #include <QObject>

    class ValueObject : public QObject

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


    #endif // VALUEOBJECT_H@

    1. valueobject.cpp

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

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

    qDebug() << "ValueObject" << this->objectName() << "destructed";


    #include "valueobject.h"

    @#include <QDebug>
    #include <QFile>

    int main(int argc, char *argv[])
    ValueObject o;

    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"

    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";

  • @ chris17,
