Well, it isn't that complex, no "events" involved. Just call
g_idle_add() in the other thread, passing it a callback function and a
pointer to input data for that callback function, and the callback
function will be called as soon as possible in the main thread (the
one running the GLib main loop, and by extension, the GTK+ event
processing (window message processing on Windows, X11 event processing
on X11)). Remember to return FALSE from the callback function so that
it won't be called repeatedly.
