Hmmm, puzzling... But then, there's a lot of code which you aren't 
showing. What, for instance, is panelA (and why do you use it), things 
like that.

But you'd better forget about wxLayoutConstraints altogether. The 
manual states:

   Note: constraints are now deprecated and you should use sizers
   instead. 

Don't worry: sizers are pretty easy to use. Nearly always easier than 
using constraints.
