Yes. :) 
The (invisible) root of a model is a invalid QModelIndex. That root has one child per \
tea. So for the root the code must return tealist.siez(). Each and every child, i.e. \
every tea has no child, so if the QModelIndex is valid, and is thus not the invisible \
root, the code musr return 0.
