moveToThread ( zero )
You can’t delete a QObject directly unless you do it from the thread it lives in. However, you can use object.moveToThread(0) to disassociate the object from any thread, allowing it to be deleted from anywhere. The drawback is that you can’t use queued signals/slots, but for the kind of object you would do this with it is probably not an issue.
QCA uses this trick to disassociate backend provider QObjects from threads so that they can be cleaned up from any thread. This is mainly for the public key front-end objects which are not QObjects, and so the user has an expectation that they can be copied between threads.
