Thanks Tristan,

When I said "..run in the main loop.." I mean that the object must "do
something" during its life. What I want to do is execute one object
method (main object routine) from a timeout event, and this method could
decide to fire a signal, getting special care in how many time the pack
of routines used to keep inside the timeout lapse.

Regards

Jorge

Be carefull not to mix up object based GSource's and object oriented
GObject derivitave objects, a GSource is an event source that is either
a timeout or a file descriptor watch; some have implemented ipc
mechanisms with GSource or signal handleing as well.

A GSource dispatches an event from the main loop.

When a GObject emits a signal; the signal callbacks are executed
regardless of whether there is a main loop running or not (i.e. when an
object method is called that results in a signal being fired, all
callbacks will have run and completed before the said function returns).

HTH

Cheers,
