and a control module configured to displaying on the touch screen a first application window and a second application window according to the multi-window mode, alter the first application window in response to a touchscreen input received via the touch-enabled display, and automatically alter the second application window in response to the alteration of the first application window. ## Claims ### Claim 1 An electronic device, comprising: a display displaying multi windows; and a processor functionally connected to the display, wherein the processor is configured to: display a first screen corresponding to a first application in a first window of the display; display a second screen corresponding to a second application in a second window of the display; enlarge the first window to display a third screen including an additional region that has been hidden by a size of the first screen and reduce the second window to display a fourth screen in which graphic objects output on the second screen are reduced, as a position of a boundary line is changed in response to a first user input for moving the boundary line between the first window and the second window in a first direction, when receiving the first user input; and reduce the first window to output a fifth screen including only a part of the first screen and enlarge the second window to display a sixth screen in which the graphic object is enlarged on the second screen, as the position of the boundary line is changed in response to a second user input for moving the boundary line between the first window and the second window in a second direction different from the first direction, when receiving the second user input, wherein the processor is configured to perform a control to generate the third screen by adding a new graphic object at a position spaced apart from the boundary line of the first screen by a predetermined distance. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the first application includes a music playback application, and the processor is configured to perform a control to remove an album image from the first screen and display a virtual controller related to music playback on the fifth screen while a screen displayed on the first window is changed from the first screen to the fifth screen. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the processor is configured to: generate the third screen or the fourth screen based on a graphic object disposed at a position spaced apart from the boundary line of the first screen or the second screen by a predetermined distance; or generate the fourth screen by reducing a size of a graphic object disposed at a position spaced apart from the boundary line of the second screen by a predetermined distance. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein the processor is configured to perform a control to change a display size of information displayed on the second screen while a screen displayed on the second window is changed from the second screen to the fourth screen. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the processor is configured to perform a control to enlarge a display size of information displayed on the second screen corresponding to an enlarged size of the second window to display the enlarged information while a screen displayed on the second window is changed from the second screen to the fourth screen. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein the processor is configured to perform a control to generate the fourth screen by changing arrangement of pieces of information displayed on the second screen while a screen displayed on the second window is changed from the second screen to the fourth screen. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the processor is configured to perform a control to generate the sixth screen by changing display positions of graphic objects displayed on the second screen while a screen displayed on the second window is changed from the second screen to the sixth screen. ### Claim 8 A multi-window operating method of an electronic device, comprising: displaying a second screen corresponding to a second application on a second window of a display while displaying a first screen corresponding to a first application on a first window of the display; and performing a first operation of enlarging the first window to display a third screen including an additional region that has been hidden by a size of the first screen and reducing the second window to display a fourth screen in which graphic objects output on the second screen are reduced, as a position of a boundary line is changed in response to a first user input for moving the boundary line between the first window and the second window in a first direction, when receiving the first user input; and a second operation of reducing the first window to output a fifth screen including only a part of the first screen and enlarging the second window to display a sixth screen in which the graphic object is enlarged on the second screen, as the position of the boundary line is changed in response to a second user input for moving the boundary line between the first window and the second window in a second direction different from the first direction, when receiving the second user input, wherein the first operation includes generating the third screen by adding a new graphic object at a position spaced apart from the boundary line of the first screen by a predetermined distance. ### Claim 9 (depends on 8) The multi-window operating method of an electronic device of claim 8, wherein the second application includes a music playback application, and the first operation includes removing an album image from the first screen and displaying a virtual controller related to music playback on the third screen while a screen displayed on the first window is changed from the first screen to the third screen. ### Claim 10 (depends on 8) The multi-window operating method of an electronic device of claim 8, wherein the first operation includes: generating the third screen or the fourth screen based on a graphic object disposed at a position spaced apart from the boundary line of the first screen or the second screen by a predetermined distance; or generating the fourth screen by reducing a size of a graphic object disposed at a position spaced apart from the boundary line of the second screen by a predetermined distance. ### Claim 11 (depends on 8) The multi-window operating method of an electronic device of claim 8, wherein the first operation includes changing a display size of information displayed on the second screen while a screen displayed on the second window is changed from the second screen to the fourth screen. ### Claim 12 (depends on 8) The multi-window operating method of an electronic device of claim 8, wherein the first operation includes enlarging a display size of information displayed on the second screen corresponding to an enlarged size of the second window to display the enlarged information while a screen displayed on the second window is changed from the second screen to the fourth screen. ### Claim 13 (depends on 8) The multi-window operating method of an electronic device of claim 8, wherein the first operation includes generating the fourth screen by changing arrangement of information displayed on the second screen while a screen displayed on the second window is changed from the second screen to the fourth screen. ### Claim 14 (depends on 8) The multi-window operating method of an electronic device of claim 8, wherein the second operation includes generating the sixth screen by changing arrangement of information displayed on the second screen while a screen displayed on the second window is changed from the second screen to the sixth screen.
