7. A method for operating a notification bar by an electronic device, the method comprising:

detecting an input moving an application icon, from an item area on a touch screen of the electronic device including at least one application icon, to a notification bar displayed on the touch screen; registering the moved application icon in the notification bar; displaying an item in the notification bar corresponding to the moved application icon; detecting a selection of the item in the notification bar; in response to the selection of the item in the notification bar, determining whether there is detailed information associated with the registered application icon; in response to determining that there is detailed information associated with the item, displaying a popup window displaying the detailed information without expanding the notification bar and without executing the application corresponding to the item; in response to determining that there is no detailed information associated with the item, performing a function corresponding to the item; display a memory icon in the notification bar when an external memory is mounted to the electronic device; in response to a tap event on the memory icon, display in the item area a file discovery window of the external memory; in response to detecting a hovering over a particular file in the file discovery window, output in a vicinity of the particular file a second popup window including a description of the file; and in response to a tap input selecting the particular file, display a second discovery window including a sub-directory of the selected particular file.

8. The method of claim 7 , further comprising: removing the popup window displaying the detailed information when a predetermined time has elapsed after outputting the detailed information or based on an input of a signal for removing the popup window displaying the detailed information.

9. The method of claim 7 , further comprising:

detecting an input moving the item corresponding to the application icon from the notification bar to the item area;

removing the application icon registered from the notification bar; and

ceasing display of the item corresponding to the application icon in the notification bar.

10. The method of claim 7 , wherein the detailed information comprises at least one menu for performing the function corresponding to the item.

11. The method of claim 7 , wherein the selection of the item comprises at least one of a hovering of a touch input tool, a tap, a double-touch, a multi-touch, or a gesture.

12. A non-transitory computer-readable storage medium having a computer-readable program stored therein, wherein the computer-readable program, when executed on an electronic device, causes the electronic device to:

detect an input moving an application icon, from an item area on a touch screen of the electronic device including at least one application icon, to a notification bar displayed on the touch screen, register the moved application icon in the notification bar, display an item, in the notification bar, corresponding to the moved application icon, detect a selection of the item in the notification bar, in response to the selection of the item in the notification bar, determine whether there is detailed information associated with the registered application icon, in response to determining that there is detailed information associated with the item, control the touch screen to display a popup window displaying the detailed information without expanding the notification bar and without executing the application corresponding to the item, in response to determining that there is no detailed information associated with the item, perform a function corresponding to the item; display a memory icon in the notification bar when an external memory is mounted to the electronic device, in response to a tap event on the memory icon, display in the item area a file discovery window of the external memory, in response to detecting a hovering over a particular file in the file discovery window, output in a vicinity of the particular file a second popup window including a description of the particular file, and in response to a tap input selecting the particular file, display a second discovery window including a sub-directory of the selected particular file.
