Abstract

The present invention provides an ability to generate a different layout on the screen of a calendering program. The program generates customized time slots according to the start and end points of the appointments of the day. In addition to time slots covering appointments, empty time slots will be generated but will not appear on the screen if they overlap with an existing appointment. The elimination of unnecessary images for empty time slots which are in between appointments allows for a more efficient use of space on the display screen. In compressed view mode, empty one-hour time slots will be generated to the extent necessary to fill up the screen. If in non-compressed view mode, empty time slots of one-hour duration will be added to the layout from the beginning to the end of the day.

Claims

1. A method for rendering a display of a list in a display field, wherein items in the list have a start time, an end time and associated data, comprising:

if the list is empty, draw empty slot images for a plurality of default times, beginning with a start of day time and ending with an end of day time in respective positions in the display field;

if the list is not empty, process each item in the list according to an order,

if the end time of the item is earlier than the start time of a next item according to the order, then insert at an available position in the display field a start slot image for the start time of the item followed by graphics, if any, identified by the associated data for the item, followed by an end slot image for the end time of the item if no end slot image for another item is found for the end time,

if the end time of the item matches the start time of a next item according to the order, then insert at an available position in the display field a start slot image for the start time of the item followed by graphics identified by the associated data for the item,

if the end time of the item is later than the start time of a next item according to the order, then insert at an available position in the display field a start slot image for the start time of the item followed by graphics, if any, identified by the associated data for the item, followed by an end slot image for the end time of the item if no end slot image for another item is found for the end time, and

insert empty slot images at default times for which no end time or start time occurs in the list.

2. The method of claim 1, wherein the empty slot images comprise text indicating respective default times in the plurality of default times.

3. The method of claim 1, wherein the start slot images comprise text indicating a start time for a corresponding item in the list.

4. The method of claim 1, wherein the end slot images comprise text indicating a end time for a corresponding item in the list.

5. The method of claim 1, wherein the associated data for at least on item in the list comprises text, and the graphics identified by the associated data include characters of the text.

inserting empty slot images for default times which occur after the end time of a first item in the list but do not occur between start times and end times for other items in the list,

inserting empty slot images for default times between the start of day time and the start time of an item in the list with an earliest start time, and

inserting empty slot images for default times after the end time of an item in the list having a latest end time until the first to occur of the end of day time and a condition in which a sum of the heights of the inserted start slot images, graphics indicated by associated data, end slot images and default slot images fills the display height.

12. The method of claim 1, wherein the order proceeds chronologically from the start of day to the end of day.

13. The method of claim 1, wherein the order proceeds reverse chronologically from the end of day to the start of day.

14. The method of claim 1, wherein the display field comprises a plurality of rows, and including positioning the start slot images, graphics indicated by associated data, end slot images and default slot images respectively in one or more rows in the plurality of rows.

15. The method of claim 14, including in response to input indicating the one or more rows of an empty slot image, displaying a tool for inserting an item in the list having a start time equal to the default time of the empty slot image.

16. The method of claim 14, including in response to input indicating the one or more rows of a start slot image, displaying a tool for editing the item in the list corresponding to the start slot image.

17. For a device including a touch screen input for indicating a position on a display, a method for rendering the display of a list in a display field including a plurality of display regions, wherein items in the list have a start time, an end time and associated data, comprising:
