ABSTRACT:
A grab accepting section receives a request from a grab window to grab a desired key event over a focus window. A grab requesting section which retains key event request sets that may be issued until the time a key event corresponding to the user's operation result is ascertained, requests a window system to notify all of the key events belonging to the key event request set which includes the key event that the grab window desires to acquire. Thus, in a situation where operation results of a key, which is assigned with a plurality of functions, are notified as different virtual key events for the respective functions depending on the manner the key is operated, malfunctioning due to the grab window grabbing a particular key event via the window system is avoided.
