[gtkmm] Still on threads

[Enrico Costanza <ec142 york ac uk>]

Hi all.

I have ported my code to gtkmm2, and I am still struggling with 
multithreading.

I am trying to use:
Glib::Thread::create( SigC::slot_class(*this, 
&MyCameraFramework::soundCallback), false);

(as in the example program dispatcher.cc) but the compiler complains:

no matching function for call to `Glib::Thread::create (SigC::Slot0, bool)'
/usr/include/gtkmm-2.0/glibmm/thread.h:222: candidates are:
static Glib::Thread *Glib::Thread::create (const SigC::Slot0 &, bool)
/usr/include/gtkmm-2.0/glibmm/thread.h:263:
static Glib::Thread *Glib::Thread::create (const SigC::Slot0 &, long 
unsigned int, bool, bool, Glib::ThreadPriority)

I have noticed that in the examples about threads in the documentation 
an anonimous namespace is used. Is this important to the threads?
