Just to make sure, you did call it field and not self.scrolling_widget
(which was in my example)? 

Odd that they don't start at (0,0) when adding to the bag. This is
more a wxpython question and their mailing list might prove more
useful. I could figure it out, but I cannot run the app. Trial
and error here will probably help you the most. You can also
try looking at a different sizer (like BoxSizer and GridSizer).

Personally, I think BoxSizer is the most intuitive as it matches
my thought process. You just set an orientation (vertical/horizontal) 
and add widgets to it. To get something in the other direction, you 
create another box sizer with the opposite orientation, add widgets
to that sizer, and then add the new sizer to the original sizer. Not 
nearly as pretty as grid/grid bag though (by default), but super simple.
