io.qt.QThreadAffinityException

All Implemented Interfaces:

Serializable

public class QThreadAffinityException
extends RuntimeException

The QThreadAffinityException class is thrown when a QObject is used outside its own thread. Each QObject has thread affinity, a thread that it belongs to, which is accessible through its thread() method. Accessing an object from outside this thread is forbidden to avoid concurrency problems. Qt Jambi checks if threading affinity is violated in each member of each QObject subclass. It is possible to disable this check by setting the VM runtime parameter io.qt.thread-check to false.
