Abstract

A method and apparatus for controlling a display of a portable electronic device are provided. The method comprises generating a screen comprising a list on the display. The list comprises one or more row elements, with each row element comprising one or more column sub-elements. At least a portion of one of the column sub-elements of at least one of the row elements is truncated. Upon selection of a row element, the screen is enabled for scrolling of that row element. Enabling scrolling comprises loading the truncated portion of the selected row element into a pre-buffer. The method further comprises receiving a scrolling input, and updating the screen on the display to scroll the row element, bringing the truncated portion into view. The selected row is scrolled while maintaining the series of column sub-elements in the row without reference to other rows.

Claims

1. A method of controlling a display of a portable electronic device, the method comprising:

generating a screen on a display, the screen comprising a list having row elements and column sub-elements, at least a portion of one of the column sub-elements comprising truncated data;

receiving a selection input for selecting a row element for scrolling; and

upon receiving the selection input, enabling the display for continuous horizontal scrolling of the row element, wherein the series of the column sub-elements of the selected row element is maintained without reference to other row elements, further comprising;

after receiving the selection input, receiving a further selection input for selecting a different row element; and

updating the screen on the display to return the previously selected row element to an initial position, wherein the previously selected row is returned to the initial position after a predetermined time period.

2. A portable electronic device comprising:

an input device;

a display;

a processor coupled to the display and configured for controlling the display, the processor configured to generate a screen on the display, the screen comprising a list having row elements and column sub-elements, at least a portion of one of the column sub-elements comprising truncated data;

the processor further configured to receive a selection input from the input device for selecting a row element for scrolling; and

upon receiving the selection input, to enable the display for continuous horizontal scrolling of the row element, wherein the series of the column sub-elements of the selected row element is maintained without reference to other row elements, the processor further being configured to receive a further selection input for selecting a different row element; and

to update the screen on the display to return the previously selected row element to an initial position, the processor further being configured to return the previously selected row to the initial position after a predetermined time period.
