         8 . (canceled) 
     
     
         9 . The method as claimed in  claim 1 , wherein, after the enlarging of the size of the at least one remaining window, the further comprising:
 discontinuing the displaying of the center button.   
     
     
         10 . (canceled) 
     
     
         11 . (canceled) 
     
     
         12 . The method as claimed in  claim 1 , wherein the center button is one of a quadrangular shape, a circular shape, an oval shape, or a polygonal shape. 
     
     
         13 . A display device, comprising:
 a touch screen configured to display a plurality of windows that do not overlap one another and that respectively correspond to executing applications, and to display a center button disposed at an intersection of a plurality of dividing lines that distinguishes the plurality of windows; and   a controller configured to control to change a size of at least one of the plurality of windows in response to a window size change command when the window size change command is input, and to control to discontinue the display of less than all of the plurality of windows and enlarge a size of at least one remaining window.   
     
     
         14 . The display device as claimed in  claim 13 , wherein the window size change command is a drag gesture that starts from the center button and ends at a first point. 
     
     
         15 . The display device as claimed in  claim 14 , wherein the controller is configured to control to move the center button where the drag gesture is input, to the first point. 
     
     
         16 . (canceled) 
     
     
         17 . (canceled) 
     
     
         18 . The display device as claimed in  claim 14 , wherein the controller is configured to control to divide the touch screen into an upper portion and a lower portion and display the at least one remaining window therein when the first point is a left boundary line or a right boundary line of the touch screen, and to control to divide the touch screen into a left portion and a right portion and display the at least one remaining window therein when the first point is an upper side boundary line or a lower side boundary line of the touch screen. 
     
     
         19 . The display device as claimed in  claim 14 , wherein the controller is configured to control to display the at least one remaining window in a full screen when the first point is an edge of the touch screen. 
     
     
         20 . (canceled)
