connecting signals and slots problem

[Lorence]

does the signal function and slot function should have the same parameters?

hi
http://doc.qt.io/qt-5/signalsandslots.html
"
The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.) "
So not sure you can mix it the way it seems you try.

Also it seems you try to include the sender in the signal ?
you can get the sender in the slot using
QObject::sender()

Hi,

You can't pass a parameter when setting up the connection and since your using Qt 5 you should try the new connect syntax, it helps avoid that mistake.

There also the possibility of using lambdas for such use case.
