If you setCursorPosition() and then use SCI_SETANCHOR (using a call to
SendScintilla()) you should (according to the Scintilla docs) get what you
want.

If this works for you then I can change the implementation of
setSelection() to do the same thing and then reversing the arguments, as
you tried, would work.
