In this chapter, you learned about the basics of how to handle events and how we can add, fire, and listen to events. You also learned about buttons, segmented buttons, menus, toolbars, and the new breadcrumb bar.

At this point, we can use the addListener or on methods to add some actions when buttons and options are clicked on, but in the next chapters, you are going to learn about how to listen for events in a more convenient way.

Also, we created as an exercise a few toolbars, and we will use them in upcoming chapters for our final application. In the next chapter, you will learn about the basics of forms that use listeners, and different ways to set items and properties inside configuration objects.
