/** |
|
33 |
* A composite Border class used to compose two Border objects |
|
34 |
* into a single border by nesting an inside Border object within |
|
35 |
* the insets of an outside Border object. |
|
36 |
* |
|
37 |
* For example, this class may be used to add blank margin space |
|
38 |
* to a component with an existing decorative border: |
|
39 |
* <p> |
|
40 |
* <code><pre> |
|
41 |
* Border border = comp.getBorder(); |
|
42 |
* Border margin = new EmptyBorder(10,10,10,10); |
|
43 |
* comp.setBorder(new CompoundBorder(border, margin)); |
|
44 |
* </pre></code> |
|
45 |
* <p> |
|
46 |
* <strong>Warning:</strong> |
|
47 |
* Serialized objects of this class will not be compatible with |
|
48 |
* future Swing releases. The current serialization support is |
|
49 |
* appropriate for short term storage or RMI between applications running |
|
50 |
* the same version of Swing. As of 1.4, support for long term storage |
|
51 |
* of all JavaBeans<sup><font size="-2">TM</font></sup> |
|
52 |
* has been added to the <code>java.beans</code> package. |
|
53 |
