However, that is separate from knowing that the button has been pushed,
so you can then start the communications. For this, is there any reason
to use a custom signal? Wouldn't it be easier to catch the standard
signal emitted when a button is pushed, by attaching a call-back routine?
Infact there is no need for a custom signal once you know about GIOChannel.
But my question was intended for general cases. If I need to trigger a
complicated task when a button is pushed I'll write a callback to manage
the standard signal in which I'll start my $COMPLEX_PROCESS then return.
The question was about how to write $COMPLEX_PROCESS: it doesn't involve
GUI so it doesn't have any standard signal, but I'd like to have the
signal-callback paradigm and I was wondering if GTK gives me some tool
or if I have to rely on an external infrastructure for it.
Maybe I'm misunderstanding something: remember, I'm really new in this
world and my questions could and probably are stupid...
