Access QObject Item from a QList

minhblabla

Hi
I got a class inherited from QObject like this:
champion.h
@#ifndef CHAMPION_H
#define CHAMPION_H

#include <QObject>

class Champions : public QObject
{
Q_OBJECT
Q_PROPERTY(QString name READ name)
Q_PROPERTY(QString color READ color)

public:

Champions(QObject *parent=0);
Champions(const QString &name, const QString &color,QObject *parent=0);
QString name() const;

QString color() const;

private:
QString c_name;
QString cc_name;

};
#endif // DATAOBJECT_H@

champion.cpp
@#include "champion.h"
#include <QDebug>

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

Champions::Champions(const QString &name, const QString &color, QObject parent)
: QObject(parent), c_name(name), cc_name(color)
{
}
QString Champions::name() const
{
return c_name;
}
QString Champions::color() const
{
return cc_name;
}
@
In my main.cpp, I created a @QList<QObject> dataList@ to add some Champions class in. Now because I want to access c_name and cc_name so I try some code like :
@datalist.at(2).name()@
or
@datalist[2].name()@
but neither of them works. Is there any method to get these items ?

You need to cast the pointer to the correct type, recommended ways are: dynamic_cast or (because you have a QObject) "qobject_cast":http://qt-project.org/doc/qt-5/qobject.html#qobject_cast:
@
Champions* item2 = qobject_cast<Champions*>(datalist.at(2));
if(item2)
item2->name();

Since it's a QObject, the correct way is qobject_cast
