removing parent is essential http://doc.qt.io/qt-5/qobject.html#moveToThread
"The object cannot be moved if it has a parent."
The children will follow to the new thread.
For the reparenting, maybe you can shed some light on it. From what I
understand, moveToThread, make that thread responsible to delete the object
and own him now (the object have the thread affinity to that thread from
now on), why can't you use a parent into that thread then?
Thread#1:
- ObjA
- ObjB as child of A
Thread#2:
- ObjC
Code:
ObjB->setParent(nullptr);
ObjB->moveToThread(Thread2);
Now you have:
Thread#1:
- ObjA
Thread#2:
- ObjC
- ObjB
why inside thread2 set parent of ObjB to ObjC is bad? to get the following:
Thread#2:
- ObjC
- ObjB as child of C
