I hav declared my AccountList as this

class AccountList: public QList<Account*>
{
}

But how do I access the accounts in the list then? Its not making sense, and I can't find any way to get to them.

I hope someone can help.

Your class AccountList is derived from QList<T*>
this means it contains pointers of type T.
In this case it T is Account a class.

Because AccountList is derived from QList it just needs a loop to iterate through each item.

I used

Language: C++
foreach (Account *acc, *this)
    {
      //statments
    }

You could use any of the Mutliating iterator loops given in chapter 4 like

Language: C++ (QT)
for (QStringList::iterator it = list.begin(); it != list.end(); ++it)
    {
        QString current = *it; 
        qDebug() << "[[" << current << "]]";
    }
 
//while loop with iterator
QListIterator<QString> itr (list2);
    while (itr.hasNext())
    {
        QString current = itr.next();
        qDebug() << "{" << current << "}";
    }

I hope this helps.

Thanks for the help toxic, but I'm still confused. m_AcctNum is still private...how do I access it?

What I did do was to create a get function in class Account, but I don't think this is right.
