interacting C++ QML

[kickoune]

hello,
i would like understand qt, so i post here.

rmq: QT : 5.7


if i setProperty class in my qml.
in this class, i have method Q_INVOKABLE what we return a pointeur in class.

like this with no var in my qml:

if (toto.test()!=NULL)
toto.test().x() //method Q_INVOKABLE x()

work but , the qml want manage the cobject returned by test()

if i quit the qml page.
qt would like delete the object returned by test() why??

i would like juste interacting C++ and QML.

what is the best method for use this? (no manage memory who i return in my q_INVOKABLE function)
