Revision 6102
Date: 2010-10-12 06:58:45 -0700 (Tue, 12 Oct 2010)
Author: Ed
Trac: http://trac.dabodev.com/changeset/6102
Changed:
U trunk/dabo/ui/uiwx/dTextBoxMixin.py
Log:
Added the 'charsBeforeCursor()' and 'charsAfterCursor()' methods, as requested
by Brendan Barnwell. By default, they return the character immediately
before/after the insertion point, or if there is selected text, before/after
the selection. You can optionally pass the number of characters to return if
you want more than one. You can also specify that any selected text be included
in the return value; by default it is not.
I'm open to renaming these methods, as I find them rather clunky, but can't
think of anything better at the moment.
