Not completly true, you can get the item with the function 
QTreeView.indexAt(pos)

Here is a small example:

    def showCustomContextMenu(self, pos):
        index = self.treeview.indexAt(pos)

        if not index.isValid():
            return

        item = self.treeview.itemAt(pos)
        name = item.text(0)

        menu = QMenu(self)

       # your menu...

        menu.popup(QCursor.pos())
