Welcome to wxCocoa wxCocoa is still very much a work in progress. At this point quite a bit of functionality is working, but quite a bit is left to do. wxCocoa is not yet suitable for a direct port of most wxWidgets applications. Fortunately, wxMac is available for those looking to move to Mac today. If you're still reading then I assume you're interested in helping with the wxCocoa port. Please join the wx-dev@lists.wxwindows.org mailing list so we can talk! There is plenty of work that can be done independently. For example, many of the controls (listboxes, sliders, gauges, steppers, etc.) can be easily worked on and the implementation should be pretty straightforward (see how wxButton is wired up for an example of how to handle events). I welcome any help, but please shoot a message to wx-dev or to me privately, dfe@cox.net, so there is no needless duplication of work. Thanks a bunch! David Elliott
