/** |
|

* The listener interface for receiving keyboard focus events on |
|
32 |
* a component. |
|
33 |
* The class that is interested in processing a focus event |
|
34 |
* either implements this interface (and all the methods it |
|
35 |
* contains) or extends the abstract <code>FocusAdapter</code> class |
|
36 |
* (overriding only the methods of interest). |
|
37 |
* The listener object created from that class is then registered with a |
|
38 |
* component using the component's <code>addFocusListener</code> |
|
39 |
* method. When the component gains or loses the keyboard focus, |
|
40 |
* the relevant method in the listener object |
|
41 |
* is invoked, and the <code>FocusEvent</code> is passed to it. |
|
