qthread destroyed while thread is still running

 

qthread destroyed while thread is still running

 

然后报错（windows下）：QThread: Destroyed while thread is still running，程序直接崩溃
解决办法：在select_t.start()后面跟一句select_t.exec()保护一下

        select_t = SelectModuleThread()  # 通过创建一个继承QThread的类的线程对象
        select_t.my_signal.connect(self.set_num)   # 线程对象绑定信号
        select_t.start()  # 线程启动
        select_t.exec()

 

exec()在官方文档中的属性是protected，作用为使线程进入时间循环状态，并且处于wait状态，直到退出。
