Event Objects  
  • When you receive an event either in handleEvent() or in another event method, the event you receive is described by an Event object defined in (java.awt.Event).

  • An event object contains a number of public variables that describe the event. For example, the most often used is event.target, which is the originator of the event. Thus, if a button is pressed and an action event is posted, the target field will equal the button that generated the event.

  • The following table outlines some of the other properties

Object targetThe object receiving the event.
long whenEvent time stamp.
int idThe type of the event.
int xThe x coordinate of the event.
int yThe y coordinate of the event.
int keyThe key that was pressed, if any.
int modifiersThe state of the modifier keys, if any.
int clickCountThe number of consecutive mouse clicks, if any.
Object argAn arbitrary argument.

  • You can easily use any of this information inyour event handling logic in order to perform tests, debugging or anything else.
