The general rule in wxWidgets is that events are not sent when values 
are changed programatically.  (There are exceptions to this, mainly 
those that were already sending an event before the rule was made.)  So 
your options are to either send the event yourself, or refactor your 
event handler so it calls another method to do its work that you can 
also call yourself after doing the SetValue.
