Please help me modify multi-threading or give me some proof. I just want him to output the log into the text box. . .

def hanshu(b) Isn’t this right? Can I quote self.xxx here? You can pass the value in in the form of def hanshu(xx,yy,b) and then try again. When using it, it is hanshu(self.xx,self.yy,b). Do you understand what I mean?
