[gtkmm] Timer Question

[Dean Kutryk <trollking shaw ca>]

I want an object to send a signal to another object (a control class)
after a timed interval, beginning when the object is created. After the
time has expired, the object will send a signal, than it will be
eligible for destruction. At any rate, how would I manage the time
feature in Gtkmm or Gtk+? Do I have to use the system clock or
something?
