In wxGTK many controls are not true windows but are just drawn directly 
on their parent.  I didn't think that wxTextCtrl was this way but it 
could be.

Not that I know of, other than padding the value with leading spaces...

Yep, see above.

I think that the widget in GTK2 does support right-aligned text, but I 
don't know if wxGTK2 is supporting it yet.  Doesn't look like it is 
doing anything with the wxTE_RIGHT style in the code.  Enter a feature 
request for it so it doesn't get lost.
