QFutureWatcher 发出finished信号的线程是谁？
MyClass myObject; QFutureWatcher<int> watcher; connect(&watcher, SIGNAL(finished()), &myObject, SLOT(handleFinished()));
// Start the computation. QFuture<int> future = QtConcurrent::run(...); watcher.setFuture(future);
发送信号finished()的线程是谁？是 run的新线程，还是watcher当前所在线程？不是很理解。书里面也没讲。 |
