About the time control under gtkmm-2.4

[jerry <lvjieyong cis pku edu cn>]

Hi, all
I'd like to call a special function periodically in my program , and I
find it in google that a function called
Glib::signal_timeout().connect(***) can manage this. However it's
defined in gtkmm-2.2 and I can't find a similar function in gtkmm-2.4.
What's the corresponding function in gtkmm-2.4 then? Is there any
example code for this?
Thank you in advance.
