Question

该如何释放”及QThread 的启动关闭

Answer 1

• QThread *thread = new QThread( );

• Task    *task   = new Task();

• task->moveToThread(thread);

• connect( thread, SIGNAL(started()), task, SLOT(doWork()) );

• connect( task, SIGNAL(workFinished()), thread, SLOT(quit()) );//从Qt4.4开始，qthreads-no-longer-abstract，run 默认调用 QThread::exec(),即启动消息队列

• //automatically delete thread and task object when work is done:

• connect( thread, SIGNAL(finished()), task, SLOT(deleteLater()) );

• connect( thread, SIGNAL(finished()), thread, SLOT(deleteLater()) );

• thread->start();
