[Gtk-sharp-list] Gtk# - Gtk toolkit question

[gtk-sharp@Vitalit.co.uk]

Hi,
    I am trying to develop (initially a standalone) an extensible glade
clone in c# / gtk#.  My question is :-

Is there a "bare" base set of gtk / gtk# functionality that remains the same
regardless of the gtk / gtk# versions ?

Why am I asking ?

Well I'd like to make the gui designer as flexible as possible, allowing for
the addition of widgets / extenstions to the current gtk# framework.  In
order for a long lifespan and to keep this as 'tight' as possible, I would
*like* to only have to code it once (yeah we can all dream lol).

For this to fit in the way I want it, it would be capable of having new
widgets,methods and properties added to it's layout (on systems that have
newer versions of gtk / gtk# or even for people to add some of the widgets /
methods / properties that I may miss out) whilst still being capable of
running on the "bare common" subset in order to reduce the dependency tree
(i.e. you can run it on any released combination of gtk# / gtk).

If I can figure this out I would *hope* to have a gui designer that can be
re-used as plug-ins for other projects such as monodevelop (I know that a
gui designer for monodevelop is already underway but ...... well I like a
challenge).

Cheers in advance for any help.

Matt
