使主线程等待所有其他Qthread完成 [英] Making the main thread wait till all other Qthread finished

问题描述

是有办法强制主线程等待，直到所有线程创建它，将完成他们的工作，在完成程序之前。我的意思是：

is there a way to force the main thread to wait until all threads created from it, will finish their job, before finishing the program. I mean:

int main(){
    QthreadClass a; // in cons' a thread is created and running
    QthreadClass b; // same as before

    *** wish to wait till both created thread finished their jobs ***

    return 0;

}

推荐答案

好吧，关于：

a.wait();
b.wait();

或者，你宁愿开始一个事件循环（通常为Qt应用程序）的线程结束（QThread emit finished（）和terminated（）信号）。

Or, you would rather start an event loop (as usually for Qt applications) that you quit when both of your threads end (QThread emits finished() and terminated() signals).
