[Haskell-beginners] Haskell GTK

[Emmanuel Touzery]

About this, I do not know the Haskell gtk bindings, but I know GTK.

In the example you gave it appears that the code builds the GUI by itself.

I think the code would be much more concise if it was using glade files
instead, which appears to be supported:
http://projects.haskell.org/gtk2hs/docs/tutorial/glade/

Probably with glade the code will be of acceptable verbosity.

For my own user interfaces otherwise I turned towards the web, even for
local applications (on port :8000).
