在确定使用QThread后,发现QThread - Qt for Python 官方文档写得很一般,甚至给的example都不堪入目。 我在Stack Overflow的文章找到Pyqt5注释详细的实现,Pyside6的实现也就很类似,也很可以帮助理解QThread的建立过程,以及在Python多线程之threading.Thread()基本使用和QT信号和槽在哪个线程执行问题的博客中,可以进一...
在新的线程中执行一些代码,继承QThread 重新实现 run()函数接口。 For example #include <QtCore> class Thread : public QThread { private: void run() { qDebug()<<"From worker thread: "<<currentThreadId(); } }; int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); qDeb...
结果看得头昏脑胀:好歹也自学了近1年的Qt,也一直很小心、很认真地阅读Qt和manual和例子等资料,却被突然告知,QThread的正确使用方法是一种自己从没见过,而且Qt manual、example、书籍中都没有提到过的一种方法。到底怎么了... 莫非manual、exmaple以及资料中的介绍都是错的?? 认真看看其他的人的评论,总算理清了...
For example: class WorkerThread : public QThread { Q_OBJECT void run() override { QString result; /* ... here is the expensive or blocking operation ... */ emit resultReady(result); } signals: void resultReady(const QString &s); }; void MyObject::startWorkInAThread() { Worker...
Another way to make code run in a separate thread, is to subclass QThread and reimplementrun(). For example: classWorkerThread :publicQThread{ Q_OBJECTvoidrun() override {QStringresult;/* ... here is the expensive or blocking operation ... */emitresultReady(result); }signals:voidresultRe...

workerThread(...)callsQThread::create(...)->start()and also makes sure to clean-up the thread after itself. In the simplest example the whole function body is put inside the lambda. Sometimes there is some work done before calling the worker thread with some variables on the stack, whic...
As we can see, we do not have to create a thread by ourselves. All we have to do is to define a run function with the proper parameter feeds.QtConcurrenthandles all the details for us. In this example, we used couple of APIs from QtConcurrent: ...
create(**kwargs) figure_worker = args[0] container.current = figure_worker return figure_worker This can finally be used to to expose GUI implementation in an existing python program that will run in another worker thread. from pqthreads.examples import worker @decorator_example def main(): ...
