Understanding glib events

[R K <cheesemilli gmail com>]

Hi all,

I am trying to understand the way glib uses events when using g_main_loop_run(loop). 
This is how I understand it:

The
g_main_loop_run() function checks regulary if there are events that
needs to be processed. The signal of an event is then executed by
executing the callback function. What I don't understand is when a new
event/callback function is executed. Is this when the first callback
function is completed and then a next event is handled? Or is this when
a event is dispatched by calling the callback function. Even when the
callback function is not completed yet, another event can already be
dispatched?

I expect that multiple callback functions can be handled at the same time but that only one event at at time will be dispatched.

Hopefully someone can clear this up for me a bit.

Thanks!
