Issue with getting a QString output through a function

Hi

I have a problem where I can't seem to get a output to display in a console when doing it through a function.

It works when doing it through Main(), but just blank when doing it through the function.

Below is some of my code:

Code:

---

//Main()
 
#include "ConferencePaper.h"
#include "JournalArticle.h"
#include "Reference.h"
#include <QDebug>
#include <QTextStream>
 
QTextStream cout(stdout);
 
int main()
{
    //QApplication app(argc, argv);
    QStringList list1;
    list1 << "This is a test";
 
    Reference a("Marius",list1,1,"c");  //Instance of the Reference class created with parameter values
    cout << "Title: " << a.getTitle();  //This works fine
    a.toString();
 
    return 0;
 
}

---

//Reference Function

Code:

---

#include <QString>
#include <QStringList>
#include <QTextStream>
 
#include "Reference.h"
 
Reference::Reference(QString ti, QStringList as, int ye, QString id): title(ti), authors(as), year(ye), refID(id){}
 
QString Reference::toString()
{
  return QString("Title: %1\n") .arg(getTitle());  //Does not display anything
 
}

---

Thanks

Reference::toString() does not print anything; it just builds and returns a QString. The call

Code:

---

a.toString();

---

in main() therefore builds a QString and throws it away immediately. What you probably intended was to print the QString returned by the call, as in:

Code:

---

cout << a.toString();

---

If I were you I would choose another name for the QTextStream; readers of your code will assume cout refers to std::cout.
