    Hi,

    Please use coding tags around your code.

    Your clicked method is a free function. The signature of the signal you are using contains a Boolean parameter hence the error you get.

        Why do you have slots as free functions in the first place ? Especially when you are accessing your class internal objects.

        Fix that and it will work better.

            Then you should start by reading the documentation and maybe follow a tutorial.

            Make your slot a proper member of your class.
