delete testObj;
QObject *testObj2 = new QObject;
model->setProperty(0, "obj", QVariant::fromValue<QObject*>(testObj2));
But it turns out that that doesn't work (the setValue() call within
setProperty() doesn't seem to trigger the right codepath, for some
reason), and you can't trigger it manually via:
QObject *testObj2 = new QObject;
void *a[] = { testObj2, 0 };
QMetaObject::metacall(dynamicNodeModel, QMetaObject::WriteProperty, 0, a);
because the dynamicNodeModel for that index cannot be retrieved
using the public API.
But, anyway, I think the above two test cases are sufficient to
show that QObject* values should be guarded internally.
