Yes, I have tested that on Windows and it worked well.
However, on Mac OS X it compiles but I get :

Erlang R13A (erts-5.7) [source] [smp:2:2] [rq:2] [async-threads:0] [hipe]
[kernel-poll:false]

Eshell V5.7  (abort with ^G)

I didn't find the origin of this problem.
However, I searched and found the symbol was defined in the wxWidgets
library included with Mac OS X (libwx_macud_gl-2.8.0.1.1.dylib).  Why the
library is not dynamically loaded is a mystery to me.

It looks very interesting.
However, my application will need to use a widespread format, so any user
that has basic skill in HTML can write simple extensions.


The problem is that I only started development of this library less

I am interested in anything that touches close of far GUI and Erlang.
I will have a look, thanks!



Best,
