positive.code:     }
  
      view! {
          Window {
              gtk::Box {
                  orientation: Vertical,
                  Button {
                      // By default, an event with one paramater is assumed.
                      clicked => Increment,
                      // Hence, the previous line is equivalent to:
                      // clicked(_) => Increment,
                      label: "+",
                  },

                      // Bind the text property of this Label to the counter attribute
                      // of the model.
                      // Every time the counter attribute is updated, the text property
                      // will be updated too.
