Re: minimal cairo drawing loop

Cairo is a library for drawing images, and it does not have any user
interface associated with it. The questions you ask are assuming that you
have an event loop where you have redrawing etc. That is not the case for
cairo.

That said, there are several graphics toolkits that make use of cairo. One
of them is gtk that in its latest version, gtk-3.0, uses cairo exclusively
for all its compositions. If that is what you are looking for you should
have a look at http://developer.gnome.org/gtk3/3.0/gtk-getting-started.html.
