A semantic event which indicates that a component-defined action occurred.
This high-level event is generated by a component (such as a
Button) when
the component-specific action occurs (such as being pressed).
The event is passed to every ActionListener object
that registered to receive such events using the component's
addActionListener method.
Note: To invoke an ActionEvent on a
Button using the keyboard, use the Space bar.
The object that implements the ActionListener interface
gets this ActionEvent when the event occurs. The listener
is therefore spared the details of processing individual mouse movements
and mouse clicks, and can instead process a "meaningful" (semantic)
event like "button pressed".
An unspecified behavior will be caused if the id parameter
of any particular ActionEvent instance is not
in the range from ACTION_FIRST to ACTION_LAST.
