I've an example which might be helpfull for you. It uses a Thread,
Syncing and Dispatcher ( it is not much code but many comments,
unfortunately in german at the moment )
Depending what compression you prefer:

or
http://evilissimo-softdev.de/files/downloads/gtkmm_tut/example3/gtkmm_example3.tar.gz
or
http://evilissimo-softdev.de/files/downloads/gtkmm_tut/example3/gtkmm_example3.zip
This is inspired from Daniel Elstner Glib::Dispatcher example which can
be found here: http://cvs.gnome.org/viewcvs/gtkmm-root/examples/thread/

Get method or something, which of course must be threadsafe, too.
Yes, I could do that, I just hoped there would be a cleaner approach
which doesn't involve altering the class interface.
As to thread-safety, can you give me any hints what I have to watch
out for when programming a thread-safe getter/singleton? I am familiar
with the basics of concurrency and aware of most of its more common
problems such as races and deadlocks, but I have never programmed with
threads in C++ before and am not familiar with the means involved
there (especially since threading facilities are not implemented on
the language level but have to be incorporated from 3rd party
libraries--in this case glibmm I guess).
Thanks a lot,
Matthias
