I think I am confused now too.

What type is self.startTime?  I assume that is the object you are 
creating with your XRC subclass?

If it is not a TimeCtrl, but contains one, then yes, you'll need to do 
something like self.startTime.timeCtrl to get to it, but if 
self.startTime.timeCtrl is not created until the OnCreate then it may 
not exist yet.  One approach you can take is to move the event handler 
to the WorkoutTime class and do the binding in OnCreate.  Then the 
handler can call a method in the parent if needed, or perhaps just send 
a message, or whatever.
