depth of QTreeWidgetItem

hi.
I'm having a problem with QTreeWidget. i have tree data of unknown depth (readed from XML file), so i'm wondering which is the easiest way to get depth of selected item, so i could take needed indexes of all its parents.
for illustartion, some code:

Code:

---

class cdNamespace  
{
public:
	cdNamespace();
 
	qint32 ID;
	QString Name;
	QString Description;
	QVector<cdObject> Objects;
	qint32 NumberOfObjects(void);
	QVector<cdNamespace> Namespaces;
	qint32 NumberOfNamespaces(void);
}

---

My tree control is having unknown depth trough namespaces, and i need to know which namespace is selected. objects are also displayed in tree, which make this even more difficult.
I have an idea to to this with recursive function, but maybe there is an esier way?

thanx

Code:

---

int depth = 0;
QTreeWidgetItem *item = ...;
while(item!=0){
  depth++;
  item = item->parent();
}

---

:) So simple :) Thanx

Ok depth is working fine. Now i need to get item index.
This shoud give index of item:

Code:

---

qint32 _Index=_Item->parent()->indexOfChild(_Item);

---

but it's not working. Hint?
