        Title("Hello world");
        button.SetLabel("Hello world!");
        button << [=] {
            if (PromptYesNo("Button was clicked. Do you want to quit?"))
                Break();
        };
        Add(button.HSizePos(100, 100).VSizePos(100, 100));
    }
    
private:
    Button button;
};

GUI_APP_MAIN
{
