QThread: Destroyed while thread is still running

QThread: Destroyed while thread is still running

原因：python中线程不能是临时变量，

错误代码：

  

   

    

     

    
    

     
 for cam in cams:
     
    
   

    

     

    
    

     

       mdcall_thread = Multi_dllcall_q()
     
    
   

    

     

    
    

     

       mdcall_thread.param(cv_dll, cam[0], cam[1], cam[2], cam[3])
     
    
   

    

     

    
    

     

       mdcall_thread.start()
     
    
   

    

     

    
    

     
 while True:
     
    
   

    

     

    
    

     
 pass
     
    
  
 

线程会自动释放掉。

解决方法：

如果是一个线程：

 self.mdcall_thread = Multi_dllcall_q()
        self.mdcall_thread.param(cv_dll, cam[0], cam[1], cam[2], cam[3])
        self.mdcall_thread.start()

如果批量线程，正确代码：

 aa=[]
    for cam in cams:
        mdcall_thread = Multi_dllcall_q()
        mdcall_thread.param(cv_dll, cam[0], cam[1], cam[2], cam[3])
        aa.append(mdcall_thread)
        mdcall_thread.start()
