# here we call setUseParentModel before the parent is known!

c.setUseParentModel(True)

# we prepare the layouts

m.setLayout(Qt.QVBoxLayout())
p.setLayout(Qt.QVBoxLayout())

# Now, by adding the widgets to the layout we are actually reparenting them.
# The order in which we reparent determines success/failure:
# if we do m-->p and then c-->m, it works, but if we do it in the opposite
# order, we trigger the error.
# (i.e., if we had called "p.layout().addWidget(m)" it would work work)
m.layout().addWidget(c)
p.layout().addWidget(m)

# the problem arises because the Taurus ancestry of c is only checked when:
# a) c.setUseParentModel() is called (and it effectively changes something) or
# b) when c is Qt-reparented
##
# In this example, c is reparented before m, so when it checks for a Taurus
# ancestor, none is found. Then m is reparented and c now would find its right
# Taurus ancestor (p)... but c never gets notified!

# Manually calling c.recheckTaurusParent() after the parenting has changed is
# another way to work around this issue (you can test by uncommenting
# the following line):

# c.recheckTaurusParent()
