interrupting gtk_main

[Marisa DeMeglio <marisa dinf ne jp>]

Hi,

I am writing a GUI for an application whose events are
controlled by both the end user and a server-type
structure.  This server-type structure notifies the
GUI of new data by calling a class function.

My problem is that gtk_main() takes over and my
program  never receives anything until gtk_main_quit()
[at which point any new data is useless].

Is there a way that I can specify that a certain
function should have the authority to interrupt
gtk_main()?  I want gtk to listen for button presses,
etc, during the program execution, but I also want to
stop and update a text field when I get an outside
signal to do so.

I've looked at some of the examples which use
gtk_main_iteration(), but I'm not really sure how I
would use it here.

Any help is much appreciated!
