Connections problem

[RobM]

I have a signal in C++:

emit(mySignal(bool));

I have a connection in qml:

Connections {​​​​​​​
  target: cppObject
  onMySignal: argument ? "true" : "false"
}​​​​​​​

When I surround the connection in curly braces:

Connections {​​​​​​​​
  target: cppObject
  onMySignal: {​​​​​​​ argument ? "true" : "false" }​​​​​​​
}​​​​​​​​

I get a ReferenceError that argument is not defined, but not with the curly braces, why is this?

What is argument here ? Either way it should give you problem. Argument should be variable name defined in your signal. I did not see that. Also when you emit the signal, you should give the value than type. Here you are adding as bool. It should true/false
