CHAPTER 4

Pickers 4

A picker is a black-bordered, unmovable view that pops up in response to a

user action, such as tapping a button, label, or hot spot. A picker contains a

set of items such as commands, attributes, states, or application data. The

items may be presented as a simple list, a table with rows and columns, a

numerical counter, or a calendar, and those formats can be mixed in a single

picker. Users can choose an item or merely browse the picker. Most pickers

close immediately when a user chooses an item, but the more elaborate

pickers have a Close box that a user taps after choosing an item. Also, most

types of pickers close if a user taps outside them.

This chapter details the appearance and behavior of the following types of

Newton pickers:

■ List pickers

■ Number pickers

■ Date and time pickers

■ Data overview pickers

This chapter ends with brief descriptions of prefabricated Newton pickers that

pop up in many applications: the Info, New, Show, Action, and People pickers.
