Nice feature, I didn't know it was possible. However TeXmacs cannot use XIB
files since all the GUI elements are generated programmatically from the scheme
code. TeXmacs is inspired by Emacs and all the features of the user interface
can be reprogrammed on the fly without recompiling. For example menus and
toolbars are described by scheme code and we are also developing a full set of
widgets which can be used by the user to write his own plugins. An example is
the following piece of code
(tm-widget (widget4)
(centered
(resize "200px" "50px"
(scrollable
(choice (display* answer "\n")
'("First" "Second" "Third" "Fourth" "Fifth" "Sixth")
"Third")))
======
(resize "200px" "150px"
(choices (display* answer "\n")
'("First" "Second" "Third" "Fourth" "Fifth" "Sixth")
'("Third" "Fifth")))))
which produces a widget with some fields. To implement this kind of logic we
really need auto layout features. Qt has them and things work quite nicely
there. I was a bit worried about having to reimplement all that for AppKit but
now I found Renaissance and it seems really what I was looking for. Note that
we do not aim to being able to produce full blown applications from scheme,
just to have simple dialogs (like preferences panes or toolbars) which the
users can reprogram at will without having to understand much of the underlying
system and in quite natural ways.
