yo Todd Gayley (and of course the rest of the group), the MathListener Util classes in J/Link make it very easy to write GUI code, without writing (an deploying) classes; but, as soon as you need a Listener not defined in J/Link, you have to write Java Code again (eg if you use some of the Swing Listeners like ChangeListener (for JSlider)); I thinks it is possible to use the JDK 1.3 Dynamic Proxy API to add this to J/Link; I know that everyone could use the DynamicProxy things on their own, but having a little Utility class that hides all the ugly details would make J/Link even more useful; something like MathGenericListener, with a setHandler method like the other Math*Listeners; one drawback would be that at least JDK 1.3 would be required, but that shouldn't be too much of a problem (except for the 4 or 5 MacOS 9 users ;) ); murphee ************ my site: www.angelfire.com/co/werners a must: www.linuxtoday.com so is this: www.javaworld.com as well as: www.userfriendly.org/static ************ "... and the fact that I haven't put a gun to my mouth yet, makes me a winner!"
