Pickers, Pop-up Views, and Overviews
Specifying the List of Items for a Popup
6-39
Table 6-3 describes the frame required to specify a two-dimensional grid item in
the picker list.
indent
An integer that defines a text indent to use for this item and
subsequent icon/string items. This integer specifies the
number of pixels to indent the text from the left side of the
picker view. You can use it to line up a number of text items
that may have icons of varying width. Specify ­1 to cancel
the indent effect for the current and subsequent text items.
The icon is always centered within the indent width.
fixedHeight
You can give this slot for the first item in order to force all
items to be the same size. If you use icons in a list that can
become large enough to scroll, you should specify the
fixedHeight
slot for every item. You can also use this
slot for any item to specify a height different from other
items. (When you use P
opupMenu
, you must specify a
fixedHeight
slot for the first item, because P
opupMenu
ignores the height of the icon.)
