[webquinty]

QTreeWidgetItem *child = /*currentItem() or whatever*/;
QTreeWidgetItem *parent = child->parent(); //check if valid
QTreeWidgetItem *grandparent = parent->parent(); //check if valid
int index_child = parent->indexOfChild(child);
int index_parent = grandparent->indexOfChild(parent);

QTreeWidgetItem *child = /*currentItem() or whatever*/;
QTreeWidgetItem *parent = child->parent(); //check if valid
QTreeWidgetItem *grandparent = parent->parent(); //check if valid
int index_child = parent->indexOfChild(child);
int index_parent = grandparent->indexOfChild(parent);
