QT record of some problems in signal slot connection

I have met several times in my work connect To connect the signal slot , There are some error reporting problems

1. There is a problem in compiling that no slot function is found

QObject::connect: No such slot UserLogin::Login_Result(bool result,QString msg) in ..\FAWVW_BlueTest\BlueTest\userlogin.cpp:28
QObject::connect:  (receiver name: 'UserLogin')

Post my wrong source code

connect(Global::pMesPlatform,SIGNAL(Sign_MesResult(bool ,QString)),this,SLOT(Mes_UpLoadResp(bool result,QString message)));
}

Through help documents , You can see the use of SIGNAL,SLOT When it comes to the way , The signal slot function only needs to fill in the parameter type , Cannot fill in parameters ; So to Mes_UpLoadResp(bool ,QString )

summary ： Use connect(sender,SIGNAL(),reciver,SLOT()) Connect the signal slot in the same way , Generally used for overloaded signal slot function , That is, there are multiple functions with the same name but different parameter types or different numbers

If there is no such situation , This is recommended connect The way ：

connect(Global::pMesPlatform,&MesPlatform::Sign_MesResult,this,&MainWindow::Mes_UpLoadResp);
