[gtkmm] Problem with main loops/heavy load

["Leslie P. Polzer" <leslie polzer gmx net>]

Greetings,

I have a small problem which I am not able to solve on my own.
I have a processing function connected to a signal_timeout which
is called 24 times a second. The updating of the GUI elements
is therefore very slow. In GTK FAQ it is stated for GTK1 that
the processing function should do this:

while (g_main_iteration(FALSE));

(which is deprecated)
...so I figured out I should do something like this in gtkmm2:

Gtk::Main::iteration(false);

or this:

while ( (Glib::MainContext::get_default())->iteration(false) );

...but neither one of these work the way I thought they'd do:
Instead the whole thing is suspended until some event comes in
(mouse movement or whatever) and immediately blocks again after
it has processed the event.
What's wrong? I am passing 'false' to the blocking parameter
both times.


Best regards,

Leslie
