如果你确实要删除，请参阅void QObject::deleteLater () [slot]这个槽，这个槽非常有用，尤其是对局部线程来说。后面会经常用到它用于安全的结束线程。...还有一种方法是让QThread自己删除自己，就是在new线程时，不指定父对象，通过绑定**void QObject::deleteLater () [slot]**槽让它自动释放。...);//线程结束后调用deleteLater来销毁分配的内存 thread->start(); } 这个例子还是启动之前的线程，但不同的是： new ThreadFromQThread(NULL...);并没有给他指定父对象 connect(thread,&QThread::finished ,thread,&QObject::deleteLater);线程结束后调用deleteLater来销毁分配的内存...再线程运行完成，发射finished信号后会调用deleteLater函数，在确认消息循环中没有这个线程的对象后会销毁。
参数用于超时中断设置； QTimer::singleShot为单次定时器； 当定时器超时后则会执行 onTimeout函数； 而 onTimeout函数会执行 QNetworkReply的 abort和 deleteLater...QNetworkReply*>(parent()); if (reply->isRunning()) { reply->abort(); reply->deleteLater
->moveToThread(&workerThread); connect(&workerThread, &QThread::finished, worker, &QObject::deleteLater...MyObject::handleResults); connect(workerThread, &WorkerThread::finished, workerThread, &QObject::deleteLater
开发中手动回收资源时建议使用deleteLater代替delete,因为deleteLater多次是安全的。
QObject::connect(socket, &QTcpSocket::disconnected, [socket] () { qDebug()<< "DISCONNECTED "; socket->deleteLater...), [socket](QAbstractSocket::SocketError) { qDebug()errorString(); socket->deleteLater...[dlg, this](int result) { if (result) { QFile file(dlg->selectedFiles().first()); // … } dlg->deleteLater...include class Goo : public QObject { Goo() { connect(this, &Goo::someSignal, this, &QObject::deleteLater
parserWorker->moveToThread(parserThread); connect(parserThread, &QThread::finished, parserWorker, &QObject::deleteLater...senderWorker->moveToThread(senderThread); connect(senderThread, &QThread::finished, senderWorker, &QObject::deleteLater...uartWorker->moveToThread(uartThread); connect(uartThread, &QThread::finished, uartWorker, &QObject::deleteLater...fileWorker->moveToThread(fileThread); connect(fileThread, &QThread::finished, fileWorker, &QObject::deleteLater...parseWorker->moveToThread(parserThread); connect(parserThread, &QThread::finished, parseWorker, &QObject::deleteLater
This signal can be connected to QObject::deleteLater()，to free objects in that thread....这句话的意思是将finished绑定到QObject::deleteLater()槽函数可以实现线程的自动销毁。...~TestThread() { qDebug() << “~TestThread”; } 在widget.cpp中绑定finished信号与QObject::deleteLater...ShowDownloadProgress(int)),this,SLOT(ProgressLabelShow(int))); connect(thread,SIGNAL(finished()),thread,SLOT(deleteLater...())); thread->start(); 其中，信号的发送者和接收者都是新创建的thread对象，槽函数为deleteLater()，该槽函数是继承自QObject的。

安全地删除QObject派生类请使用deleteLater()。 批量删除对象列表可以使用qDeleteAll()。 所有派生于QObject的类都不能拷贝构造和赋值操作。
