Items and Buttons
This book has so far focused on how the application can display information to users. In this chapter and the next, you will examine constructs that allow users to send information back to the application. These constructs, which are items and buttons, are known as form controls because they typically appear in web forms.
There are many types of items, which look and behave quite differently from each other. However, they all can be understood as variations of a few basic concepts. The purpose of this chapter is to explore these concepts and examine how they are embodied in the different item types.
