Reimplemented QStandardItem

[Miga]

Hello!
I've got QTreeView and QStandardItemModel. There are items in this model based on QStandardItem:

class  TComplexItem : public QStandardItem
{
public:
 
const TElement *getElement() const;
void setElementData(const TElement & element);
 
private:
    TElement *m_pElement; //string and integer members in class TElement
}

class  TComplexItem : public QStandardItem
{
public:

const TElement *getElement() const;
void setElementData(const TElement & element);

private:
    TElement *m_pElement; //string and integer members in class TElement
}

To copy to clipboard, switch view to plain text mode 

It's now necessary to add to the window with QTreeView some controls for representation data from m_pElement. So when we walk though the tree we should get the appropriate data for current item in these controls.
How could I do this? It looks like QDataWidgetMapper. But QDataWidgetMapper itself doesn't fit here.

Thanks in advance for any ideas.
