Searching for simple gtkmm applications

[squall23 <squall23 gmx at>]

Hi!

After reading the gtkmm online book I am looking for some neatly coded
gtkmm applications.
I am hoping to get a better understanding of the toolkit by studying the
code of these programs.

Basically I am especially interested in applications which are using
state of the art gtkmm programming
in conjunction with glibmm (threads, regex, sockets,...).
Furthermore it is important that a good coding practice is used.

So which programs would you recommend for studying?

regards
