Adapted below:

" The child of a QObject must always be created in the thread where the
|
||
|
|
parent was created. This implies, among other things, that you should
|
||
|
|
never pass the QThread object (this) as the parent of an object created
|
||
|
|
in the thread (since the QThread object itself was created in another thread)."
