I have two tiny libraries that I have been slowly putting my most
common GUI abstractions into.
This is the GUI abstractions -- basically meta-widgets built from wx
parts. Like a yes/no modals that return actual booleans instead of
building one each time from buttons/images/references, and grid
structure boxes with headers and labels you can pass in as two lists
and get the constructed reference back (along with a function for
looping through the results, etc.). It is very basic and still lacks
some of the more interesting things I want to do (like 2D and 3D
paint frames within which abstract widget drawing functions can be
used -- basically taking a page out of game widget libs).
Jumptext [imaginary URL goes here]
This one does i18n, and they work together to refresh the skin,
text strings, manage the text strings, etc. It is still unreleased
because it is in a vague legal status (I wrote it, but do I own it if it
was on contract? etc). I will need the same thing later anyway, so I'll
probably wind up re-writing nearly the same thing again and putting it
The glaring omission is the gen_gui behavior I've yet to include in
zxWidgets. There is a very straightforward pattern I've established
for getting the core wx bits up and running, and passing the unhandled
wx* messages through to a callback module, but I've just not gotten
around to formalizing it as a module yet. Which is silly of me, but
this is all unpaid work. :-(

Yes. This complaint was my exact motivation for starting on zxWidgets.
Unfortunately the project that was paying for that party got put on hold
for a bit, but will probably be revived later.
I *really* want to provide a functional style lib over the 2D and 3D
