27  * Trivial implementation of TabbedContainerBridge for use with unit tests, etc.
28  * Does not actually support changing tabs, this is just so things link and do not
29  * throw NPEs.
30  * <p>
31  * Given sufficient interest, a JTabbedPane implementation could be provided,
32  * though there are some non-trivial difficulties getting a JTabbedPane to show
33  * the same component for all tabs, and the technique that worked on 1.4 does not
34  * work on 1.5.
