将PyQt4信号转换为PyQt5信号无效

I am trying to convert a game from PyQt4 to PyQt5 and I am having some difficulty converting to the newer signal types. So I have gone back into the original and I am trying to convert the signal first using PyQt4. The commented line is the old (working) version, underneath it the new version. However the 'new' version is always passing the same value to the event handler: 0. I have tried many subtly different versions, nothing seems to work. Ideas?I am trying to convert a game from PyQt4 to PyQ
