Pickers, Pop-up Views, and Overviews

Specifying the List of Items for a Popup

Table 6-2 describes the frame used to specify a string with an icon in the picker list.

Item frame for strings and bitmaps

item

The item string or bitmap reference.

pickable

A flag that determines whether the item is pickable.
Specify non-

nil

if you want the item to be pickable, or

nil

if you don't want the item pickable. Not-pickable

items appear in the list but are not highlighted and can't be
selected.

mark

A character displayed next to an item when it's chosen.
Specify a dollar sign followed by the character you want to
use to mark this item if it is chosen. For example,

$\uFC0B

specifies the check mark symbol. (You can use the constant

kCheckMarkChar

to specify the check mark character.)

fixedHeight

When you give a bitmap, you can give this slot for the first
item in order to force all items to be the same size. If you
use bitmaps in a list that can become large enough to
scroll, you should specify the

fixedHeight

slot for

every item. You can also use slot this for any item to
specify a height different from other items.

Item frame for string with icon

item

The item string.

icon

A bitmap frame, as returned from the compile-time function

GetPictAsBits

. The bitmap is displayed to the left of the

text, and the text is drawn flush against it, unless the

indent

slot is specified.
