[Chicken-users] Chicken and GUI programming

[Michele La Monaca]

Hi,

I am investigating the feasibility and the opportunity to write
(basic) Win32 GUI apps using Chicken. So far I think I've obtained
good results leveraging Christian Kellermann's nice technique to
handle callbacks
(http://pestilenz.org/~ckeen/blog/posts/callbacks.html)*.  I am able
to create windows, add widgets, react to events and so on.
Unfortunately I've stumbled upon a problem I am not able to overcome.
When the app engages in long running operations, the (scheme)
procedure in charge of handling GUI's events starves, with the net
effect that the app seems to freeze.

So my question is: it's just me not properly using Chicken's
"cooperative" threads (which might be well the case since I am not
accustomed to those), or I've hit an intrinsic limit of Chicken being
single threaded (in the pthread sense of "concurrent" threads)?

Ciao,
Michele
