Access item in ListView's delegate

[MartinD]

I have a signal and ListView:

   signal userEdited(User user)

    ListView {
        delegate: userListDelegate
        model: userList
    }

and then the delegate component which contains button:

Component {
      id: userListDelegate
      Button{
        onClicked: {
            // here I want to emit signal with a user which is represented by the delegate
            //emit buttonClicked()
       }
      }
}

On button click, I want to emit the signal, however I don't know how to access the whole user object of the delegate and pass it as the signal's parameter.
