SpinCtrl does use native objects, but there's no native combination  
of SpinButton and TextCtrl, so we combine them in wx. There are a  
couple other cases where we do something like this (e.g. wxSlider's  
labels, as the native control has no labels concept).

As for ComboBox, it's a long story, but the gist of it is that Carbon  
(Apple's C++ bindings) did not have a native ComboBox control until  
Panther or Tiger (can't remember which), and when they finally did  
release it, we found out that it didn't fire an event for when the  
selection changed, making it unusable in our case. ;-/ (There is an  
implementation in wx sources, though.) I'm not sure if that's been  
fixed yet, but I do know Apple said it was going to be fixed, so at  
some point I plan to look into it again.

In general, Carbon works well, but Apple does give more attention to  
Cocoa than Carbon, so there are a few rough spots that we've had to  
deal with. Of course, the reason we use Carbon is that there was a  
wxMac port for older Mac versions that was largely reusable for OS X.

Glad to hear you like it! :-)

BTW, thanks for the updates on XRCEd! I'm really looking forward to  
the custom control stuff (I'd like to add support for SizedControls)  
and also the IDE embedding stuff. :-)

Kevin
