Why code completion does not work, what's wrong on my code?

@#include <QObject>
#include <QStringList>

class MyClass : public QObject
{
Q_OBJECT

public:
explicit MyClass(QObject *parent = 0);
explicit MyClass(const MyClass &myclass, QObject *parent = 0);
MyClass &operator=(const MyClass &myclass);
QString &operator[](int i);

public slots:
void append(const QString &name);

private:
QStringList m_name;

};

//---------------------------------------------------------

MyClass::MyClass(QObject *parent) :
QObject(parent)
{
}

MyClass::MyClass(const MyClass &myclass, QObject *parent) :
QObject(parent)
{
*this = myclass;
}

MyClass &MyClass::operator =(const MyClass &myClass)
{
m_name = myClass.m_name;
return *this;
}

QString &MyClass::operator [](int i)
{
return m_name[i];
}

void MyClass::append(const QString &name)
{
m_name.append(name);
}

//---------------------------------------------------------

#include "mainwindow.h"
#include "myclass.h"

MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
MyClass a;
MyClass b(a);
b[0]. // where code completion does not work.

MyClass c;
c = a;
c[0]. // work fine.

Are you taking about auto complete in QtCreator IDE ? May be it is not able to identify 'b' as object due to default parameter. Create object with correct number of parameter in constructor

e.g MyClass b(a,0);

Then it start showing it. May be bug in QtCreator iDE.

Yes, it's in Qt Creator.
If provide with full number of parameter it's work fine.
I just worry about my code what I do wrong why IDE can't detect.
So it's just a bug?
