CHAPTER 4

Pickers

Overview Pickers 4-21

Using an Overview Picker 4

A user makes an overview picker appear by tapping the appropriate label.

The picker stays open until the user taps its Close box. The user does not

have to press and hold the pen on the button or label to keep the picker open.

An overview picker stays open even if a user taps, writes, or draws outside

the picker.

Picking Items 4

A user selects items listed in an overview picker by tapping them. A selected

item has a check mark in its checkbox. Tapping a selected item deselects it.

For selecting or deselecting, tapping an item’s name has the same effect as

tapping its checkbox.

The picker reports the number of selected items at its bottom right corner,

and the user can preview the set of selected items by tapping the Selected

Only checkbox at the bottom left of the picker. An application can suppress

the count of selected items, the Selected Only checkbox, or both in any of its

overview pickers.

If a value in the right column of an overview picker begins with a black

diamond, tapping it pops up a list picker that contains alternate values from

the stored data plus a command for entering a new value. Figure 4-16 shows

how this works in an overview picker that lists names and phone numbers.

If a user selects an item for which there is no value displayed in the right

column of an overview picker, a slip appears in which the user can enter the

needed information.

An overview picker can be set up to only allow selecting one item. In this

case selecting an item automatically deselects the previously selected item.

Setting up an overview picker for only one selection does not change the

way the picker looks (the checkbox next to each item does not change to a

radio button).
