It's talking about the proportion parameter of the AddGrowableRow or 
AddGrowableCol methods.  If you have more than one growable row/col, and 
one of them has a proportion set, then all of them should.  You only had 
one growable col, so that statement doesn't apply.  In the sizers there 
is a difference between the space allocated to an item, and how that 
item uses that space.  In general if you want an item to always fill the 
space given to it then you should use the wx.EXPAND flag.
