Message: [QUOTE="Roedy Green, post: 5020117"] The problem with subclassing is you really want to insert the methods in JComponent. You have to add them independently to every Component you want to customise. About the only help Java gives you is the interface which can be used to make sure you don't forget some of the methods, and to let you get at the methods abstractly. Seems to me I remember reading back in the 90s it was possible in SmallTalk to insert extra methods in a base class. -- Roedy Green Canadian Mind Products [URL]http://mindprod.com[/URL] The population is aging, especially in Japan and there are not enough young people to take care of them. This will stimulate the evolution of caretaker robots, at first supervised and largely controlled remotely by human nurses. Over time they will work more and more independently doing tasks like bathing, feeding, cleaning up, dispensing medications and acting as companions by playing games and conversing. The technology can then be loosed on mankind's most vexing problem -- being sexually attracted to people who have no interest back. .. [/QUOTE]
