Presumably this is pain that many other folk (for example the wxWidgets up-stream developers) are also experiencing, so eventually there should be some appropriate lore and pattern to lean on. I notice on the wxWidgets site that there is a wxOSX/Cocoa that runs in 32 and 64-bit modes at an "alpha" stage. I understand that Matthew wants to move away from using wxWidgets, though. [OT: I've been wondering how to deal with the change myself. I haven't met a description of how to call out to objective-C methods from C, yet, only the other way around. Anyone know of a how-to or tutorial? Or is the only approach to make a cocoa application that calls back to the C "main" code somehow (inverting the call graph).] Cheers, -- Andrew _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-dev
