Qt: Using multithreading to end times wrong questions

After multiple threads are created, an error pops up if the resource is not reclaimed before the program is closed.

1. In general, a direct call to the thread's Quit () method ends the process and reclaims memory.

2. If the program is running in the process of accidental termination, such as forced shutdown, the above error will occur. Therefore, the following processing is required:

Rewrite the closeevent to reclaim the memory before closing the program. The methods used are

Thread->terminate (); thread->wait ();

具体实现为：

Closeevent (qcloseevent *ev)    {        qdebug ()<<"before wait";        Thread-Terminate ();        Thread-and-wait ();        Qdebug ()<<"afterwait";        Qmainwindow::closeevent (EV);    }
