Subclassing QStandardItem

[aLiNuSh]

Hi,

I have a QTreeView that uses a subclassed QStandardItemModel model.
The treeview should keep an user list for a chat program.

What I want to do is to subclass QStandardItem in order to make user insertion/deletion/hiding easier but I'm not sure how should I reimplement the QStandardItem * QStandardItem::clone () const [virtual] method. I know that I need to do that in order to call void QStandardItemModel::setItemPrototype ( const QStandardItem * item ) in the model.

Here's what I was thinking the derived class should look like:

class MyQStandardItem : public QStandardItem {
private:
     bool online;
     /* some other flags */
public:
     /* default constructors and overloaded ones */
     bool isOnline () const { return online; }
     /* other functions */
};

class MyQStandardItem : public QStandardItem {
private:
     bool online;
     /* some other flags */
public:
     /* default constructors and overloaded ones */
     bool isOnline () const { return online; }
     /* other functions */
};

To copy to clipboard, switch view to plain text mode 

Considering I'm not using pointers as data members should I worry about clone () ?

I'm really confused on this one.
Thanks!
