- identifying one of said other associated messages for display in the second field;
displaying a date separator item in said topmost field, wherein said date separator item is based upon said same associated date of said one of said other associated messages;
receiving a scroll command, wherein the scroll command is a request to move the vertical list up or down by one message;
identifying a next message for display in the second field after scrolling is applied and determining whether the next message is associated with the same associated date as the date separator item, andif so, maintaining display of the date separator item in the topmost field, andif not, displaying a new date separator item in said topmost field, wherein said new date separator item is based upon a date associated with said next message.

Abstract
A method of displaying messages on handheld devices. The device displays messages in a scrollable viewport of vertically arranged fields. Date separators inserted into the vertically arranged list of messages to enable the user to associate the messages 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 messages 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 message immediately below.

7. A handheld electronic device having a messaging application for reading and composing messages, each message having an associated date, a group of messages associated with a same date comprising a first message and other associated messages, the device comprising:
-
a display screen for displaying a scrollable viewport for displaying the messages, the viewport being divided into a plurality of fields arranged in a vertical list including a topmost field and a second field, the second field being immediately below the topmost field in the vertical list, wherein the number of messages exceeds the capacity of the scrollable viewport to display all of the messages at one time; an input device for receiving a scroll command from a user, wherein the scroll command is a request to move the vertical list up or down by one message; a processor connected to the display screen for controlling operation of the display screen; and a scrolling module for controlling the display of messages and the operation of the scrollable viewport, the scrolling module including a component configured to identify one of said other associated messages for display in the second field, and a component configured to display a date separator item in said topmost field, wherein said date separator item is based upon said associated date of said one of said other associated messages, and wherein said scrolling module is configured to identify a next message for display in the second field after scrolling is applied and configured to determine whether the next message is associated with the same associated date as the date separator item, and if so, maintain display of the date separator item in the topmost field, and if not, display a new date separator item in said topmost field, wherein said new date separator item is based upon a date associated with said next message. - View Dependent Claims (8, 9, 10, 11, 12)
