LexSpell is based
on the LexLib spelling checker library. While LexLib is
specifically targeted towards developers, LexSpell is actually
meant for end users.
offers an extremely simple and straight-forward programming
interface allowing developers to invoke it from within their
programs to perform spell-checking for the user.
between LexLib and LexSpell is that with the first the developer
will have to take care of a lot of low-level details, which
gives him more power, but also requires more work.
developers can simply bypass the resident invocation mechanism
of LexSpell and start spell checking over the contents of the
currently active text field.
If interested, see the Developers section for details; it's as
easy as copying and pasting the sample code!
