关于QT线程暂停、恢复、停止、重启、暂停后回收的处理

thread.h

Qmutex m_mutex; 
void threadPause();
void threadResume();  

thread.cpp

bool Flag_StopThread = 0;
bool Flag_PauseThread = 0;
void run()
{
    while(1)

            Flag_StopThread = 0;
            break;
        } 
    }
        
}


void Mythread::threadPause()
{

    this->m_mutex.lock();      
}    
void Mythread::threadResume()
{
    Flag_PauseThread = 0;
    this->m_mutex.unlock();
    
}

widget.h

Mythread* m_thread = NULL;
void on_start_clicked();
void on_pause_clicked();
void on_stop_clicked();

widget.cpp
