Wt::WPushButton *button = new Wt::WPushButton("Okay");
button->clicked().connect(SLOT(this, MyWidget::process));
}

// provide an accessor for the signal
Wt::Signal<int, std::string>& done() { return done_; }

private:
Wt::Signal<int, std::string> done_;

void process() {
done_.emit(42, "Totally done"); // emit the signal
