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.
