DISPLAYING ITEMS ON HANDHELD DEVICES

摘要

A method of displaying data items on handheld devices. The device displays data items in a scrollable viewport of vertically arranged fields. Date separators included in the vertically arranged fields to enable a user to associate the data items with a date. The date separators have “sticky” operation, meaning that the device ensures a date separator always appears within the viewport, even when the viewport has been scrolled to the middle of a long list of fields all associated with the same date. The device may ensure that the top field of the viewport always contains a date separator associated with the data item immediately below.
