Server unit, a client unit, and a recording medium in a computer system

Abstract

When having determined that the input event from a client unit is the selection of an object, a server unit requests the client unit to transmit display area information that sets a display screen area on the drawing data. The server unit acquires the display area information transmitted from the client unit in response to the request. The server unit determines whether the area of the object selected on the drawing data fits in the display screen area corresponding to the acquired display area information. If having determined that the area of the object does not fit in the display screen area, the server unit changes the display area information so that the area of the object may fit in the display screen area and transmits the changed display area information to the client unit. The client unit displays the drawing data received from the server unit.

         6 . The display controlling system according to  claim 1 , wherein the display area information changing section changes the display area information such that the area of the single object corresponds with the display screen area and the area of the single object comes at the center of a display screen. 
     
     
         7 . The display controlling system according to  claim 2 , wherein the display area information changing section changes the display area information such that the area of the single object corresponds with the display screen area and the area of the single object comes at the center of a display screen. 
     
     
         8 . A storage medium from which a computer of a server unit can read instructions and in which a process for transmitting drawing data, created in accordance with an input event from a client unit, to the client unit is recorded as a program, the program comprising the processes of:
 creating drawing data including an object according to an input event from a client unit;   determining whether the input event from the client unit is a selection of a single object included in the drawing data;   if determined that the input event from the client unit is the selection of the single object, acquiring display area information indicating where the client unit presently displays, wherein the display area information corresponds to a part of the drawing data;   judging whether a display screen area corresponding to the display area information includes a part area of the single object selected on the drawing data;   if determined that the display screen area includes the part area of the single object selected on the drawing data, changing the display area information so that the display screen area includes all area of the single object selected on the drawing data; and   controlling the client unit to display the display screen area corresponding to the display area information changed by the display area information changing section.   
     
     
         9 . The storage medium according to  claim 8 , the program further comprising:
 determining whether the area of the single object selected on the drawing data is greater than the display screen area corresponding to the display area information acquired by the display area information acquisition means.   
     
     
         10 . The storage medium according to  claim 8 , the program further comprising:
 determining whether the area of the single object selected on the drawing data is greater than the display screen area corresponding to the display area information acquired by the display area information acquisition means; and   if determined that the area of the single object selected on the drawing data is greater than the display screen area, reducing the area of the single object on the drawing data to fit the display screen area.
