Backwards compatibility

[Ian King <king eiffel com>]

Hi all,

Presently I am working on a multi-platform GUI toolkit called
EiffelVision2 that uses gtk 1.2.8 at present as the underlying
implementation on the linux/unix platform side.  This is a big ongoing
project that is trying to keep up with the latest gtk version and relies
on nearly all of the functionality gtk+ has to offer.  I have a couple
of questions that hopefully someone could answer.  Eventually we will
have to upgrade to gtk+ version 2.0, therefore :-

Is the API for gtk+ 2.0 backwards compatible with the present release
version 1.2.8, if it is not, is there a great deal of change.

What gtk objects are being deprecated (apart from gtktree, possibly
gtkctree)?

What added functionality will the new version bring?

When is the expected release of a stable version?

Thanks for your time

Ian King
