I'm not positive, but it might have something to do with 'return true;'

You might get some insight to the problem by doing this:

   return this->on_button_press_event(e);


I had a problem a week or so ago that ended up being related to 
returning 'true' instead of on_button_press_event().  I'm not sure if it 
will help you or not, but it might be worth experimenting with.
