Apparatus and method for controlling occurrence key event while a execution of graphic object

A device and a method for controlling a key event generated in graphic object processing are provided to prevent delay of screen update in display of a graphic object and prevent the screen from being continuously updated by processing no key event generated while a display event is processed. An event determiner(120) determines a type of the event generated by the user. An event manager(160) determines processing an event operation depending on the determined event type. A count checker(130) checks an event count value indicating the number of event generation and processed graphic objects by a request of the event manager. If the generated event is the key event, the event manager determines processing the event based on the event count value of the count checker. If the generated event is the display event, the event count is increased and the display event is processed.
