QTreeWidgetItem * QgsAttributesDnDTree::addItem	(	QTreeWidgetItem *	parent,
		QgsAttributesFormProperties::DnDTreeItemData	data,
		int	index = -1,
		const QIcon &	icon = QIcon()
	)

Adds a new item to a parent.

If index is -1, the item is added to the end of the parent's existing children. Otherwise it is inserted at the specified index.
