Re: GTK window winthout main iterator

[Reuben Rissler <silrep emypeople net>]

Forgive me for second guessing you, but are you definite that that your 
loop is better/easier to maintain than a Gtk main loop?

So far, if I was tempted to implement my own main loop, it wasn't 
because the Gtk main loop was inferior, but because I was looking at it 
the wrong way. Definitely check out glib_idle_add(), glib_timeout_add() 
and family.

I would love to be proved wrong, though.

Yours,
Reuben
