I guess my question is: when there is no selection, do you need...
a) the character immediately before the insertion point
b) the character immediately after the insertion point
c) n character(s) immediately before the insertion point
d) n character(s) immediately after the insertion point
e) n,m character(s) immediately before/after the insertion point
We'd also need to define what would be returned in the case where there
is selected text.

You could always override the form's validateField() method, using
something like this:
def validateField(self, ctrl):
if ctrl is self.MyEditBox:
<do some validation stuff>
else:
super(dForm, self).validateField(ctrl)
