see

for details on the new event (no docs yet afaict), it gets converted to 
a MouseWheel event automatically.

However, we don't see these auto-converted MouseWheel events in tk 
because they are sent directly to the dispatcher target and not posted 
to the event queue (which is where we process events), the solution for 
this is to install a MouseWheel event handler on the dispatcher target 
and call TkMacOSXProcessEvent() from there (similarly to the 
kEventWindowExpanded handler on the app target I've recently added for 
<Unmap> detection)

I have been planning for a while to look into reworking tkaqua event 
handling to explicitly register for the events we are interested in on 
the dispatcher target rather than handle them before dispatch from the 
event queue; as more and more interesting Carbon events are generated 
by HITooolbox internally and directly sent to the dispatcher or some 
other event target, rather than posted to the event queue.

Cheers,

Daniel
