You probably mean why Swing is *not* being used? Swing is only used for the tree. We aim - or at least Jonathan originally did - to depend as much as we can on 'normal' models. Tree is a different beast because of two things: there is no generic tree data structure in java.util (arguably, there are a couple of things that represent trees, but not in the way that would be useful for a component), and I felt that Swing's tree model was very complete and fitted right in with the kind of tree component I had in mind. The ability to reuse the model between Swing and Wicket applications was only a minor advantage to us really. Most of the models and utility classes in Swing however are geared towards drawing components on a screen, with positions, carets, paint methods, etc. Furthermore, Swing generally works in a push way: you use property change listeners etc to propagate model changes so that components may redraw themselves, while Wicket being a web application framework that works on request basis does not need that and simply re-renders components when they are relevant for a new request (e.g. the whole page with normal requests or the components in ajax request target in ajax requests), pulling the fresh model values in the process. Hence, in most cases Wicket and Swing mismatch as they are to operate in a different environment. Furthermore, we hope Wicket is still pretty minimal in the core, so if you would need to have component models that can operate in both environments it generally should be easy to accomplish. And please send a note to this list for specific problems you want to solve. Eelco ------------------------------------------------------------------------- Take Surveys. Earn Cash.
