Abstract

An electronic device, a mobile communication terminal, method and computer program product for editing data The method of editing data of an electronic device displays an item list comprising at least one item; detecting first and second touch inputs and detects a change in a distance between first and second touch input points. The method executes a predetermined function related to the item list according to the detected distance change.

Claims

1. A method of editing data of an electronic device having a memory, the method comprising:

retrieving, by the electronic device, an item list from the memory, the item list comprising a plurality of items;

displaying, by the electronic device, the item list on a touch screen of the electronic device;

detecting, by the electronic device, two touch inputs at two touch input points, respectively, wherein at least one of the plurality of items is interposed in an area between the two touch input points;

detecting, by the electronic device, a difference between a first distance separating the two touch input points at a first time and a second distance separating the two touch input points at a second time; and

as a result of the detected difference between the first and second distances separating the two touch input points at the first and second times, respectively;

storing in the memory at least one new item to the item list in the area between the first and second touch input points, or

deleting from the memory at least one of the plurality of items that is interposed in the area between the first and second touch input points,

wherein the at least one new item is stored in the memory only as a result of the detected difference between the first and second distances corresponding to the first distance being smaller than the second distance, and

wherein the at least one item is deleted from the memory only as a result of the detected difference between the first and second distances corresponding to the first distance being greater than the second distance.

2. The method of claim 1, wherein the item list comprises a phonebook list containing a name and at least one contact information as one of items therein.

3. The method of claim 1, wherein the displaying of an item list comprises arranging and displaying the plurality of items in a matrix form or a sequential index form on the touch screen.

4. The method of claim 1, further comprising:

displaying one of a save and an over-write prompt.

5. An electronic device, comprising:

a memory;

a touch screen; and

a controller configured to;

retrieve an item list from the memory, the item list comprising a plurality of items,

display the item list on the touch screen,

detect two touch inputs at two touch input points, respectively,

detect a difference between a first distance separating the two touch input points at a first time and a second distance separating the two touch input points at a second time,

wherein at least one of the plurality of items is interposed in an area between the two touch input points, and

as a result of the detected difference between the first and second distances separating the two touch input points at the first and second times, respectively;

store in the memory at least one new item to the item list in the area between the first and second touch input points, or

delete from the memory at least one of the plurality of items that is interposed in the area between the first and second touch input points,

wherein the at least one new item is stored in the memory only as a result of the detected difference between the first and second distances corresponding to the first distance being smaller than the second distance, and

wherein the at least one item is deleted from the memory only as a result of the detected difference between the first and second distances corresponding to the first distance being greater than the second distance.

6. The device of claim 5, wherein the item list comprises a phonebook information list and the predetermined function relates to editing of the phonebook information list.

7. The device of claim 5, wherein said controller is configured to cause the display to display one of a save and an over-write prompt.
