13.5. Status and People List

Most instant messaging and conferencing systems provide a way for the user to indicate that he is too busy to respond, has gone out briefly, or is offline although still connected. The Status component described here is designed to give the user a way to indicate his status. In this example, every user's status appears in a PeopleList component.

There are two basic approaches to adding user status input and display. One is to build a PeopleList component that includes a combo box, to let each user select a status. The other is to build two separate components: a Status component that is visually little more than a combo box and a PeopleList that knows how to display each user's status along with his username.
