Action Event
This is a SemanticEvent which indicates that a component-defined action has occurred.
- This high-level event is generated by a component (such as a Button) when a component-specific action occurs (such as being pressed).
The event is passed to every every ActionListener object that registered to receive such events
- using the component's addActionListener method.
The object that implements the ActionListener interface gets this ActionEvent
- when the event occurs.
Hence the listener
- is spared the details of processing individual mouse movements and mouse clicks,
- can instead process a "meaningful" SemanticEvent like "button pressed".
