CHAPTER 4
Pickers
4-20 Overview Pickers
Figure 4-15 The parts of overview pickers
In most cases, your application is not responsible for the wording, punctua-
tion, or capitalization of items in either column of an overview picker. Nor is
your application responsible for the order of the items. The items are generally
taken directly from stored data.
Overview pickers display items in the bold style of the system font. On an
Apple MessagePad, the item names are 10-point text.
Position of Overview Pickers 4
The conventional position for an overview picker is centered at the bottom
of the screen. Overview pickers are large, so your application should not
attempt to position one near the diamond label or other control that makes
it appear. The usual size of an overview picker is 234 × 231 pixels.
