a semantic event which 示すs that a 構成要素-defined 活動／戦闘 occurred.
This high-level event is 生成するd by a 構成要素 (such as a Button)
when the 構成要素-明確な／細部 活動／戦闘 occurs (such as 存在 圧力（をかける）d).
The event is passed to every XActionListener 反対する
that 登録（する）d to receive such events using the 構成要素's
addActionListener method.
The 反対する that 器具／実施するs the XActionListener interface
gets this ActionEvent when the event occurs. The listener is therefore
spared the 詳細（に述べる）s of 過程ing individual mouse movements and mouse
clicks, and can instead 過程 a "meaningful" (semantic) event like
"button 圧力（をかける）d".
