Abstract
A method and apparatus for compressing and expanding a list of displayed items are provided. The items are displayed by displaying rows of informative pixels. Compressing the items entails displaying the items with one or more rows of pixels less than were immediately displayed before. The rows of pixels are displayed in accordance with a bitmap of the displayed items in which rows are indicated as displayable or non-displayable. Thus, when the compressed items are to be expanded, the status of a row needs only be changed from non-displayable to displayable in the bitmap.
