	I have to second Mr INTERLOG (or is it ACCOUNT?)
	Not sure, but I think it's a mistake in the tutorial. If you try the
first hello-world in the tutorial I have, you will find this (I think you know
the full code ;-):

void destroy (GtkWidget *widget, gpointer *data)
{
    gtk_main_quit ();
}
int main (int argc, char *argv[])
{
[...]
gtk_signal_connect (GTK_OBJECT (window), "destroy";,
                        GTK_SIGNAL_FUNC (destroy), NULL);
[...]
}

	So, this, if I call the destroy from Afterstep (middle button on tiotle
bar, then select destroy), makes :
chouchen:~/test-gtk$ hello

** ERROR **: an x io error occurred
IOT trap/Abort (core dumped)

chouchen:~/test-gtk$ gdb hello core

chouchen:~/test-gtk$


	So probably just a mistake in the tutorial that makes a bad call of the
exit functions, or I missed something? (Always remember that I'm a mssing
expert...).

	I understand for gtk_exit :
chouchen:~/test-gtk$ grep gtk_exit !$
grep gtk_exit /usr/local/include/gtk/*.h
/usr/local/include/gtk/gtkmain.h:void      gtk_exit      (gint   error_code);


but for gtk_main_quit...

chouchen:~/test-gtk$ grep gtk_main_quit !$/*.h
grep gtk_main_quit /usr/local/include/gtk/*.h
/usr/local/include/gtk/gtkmain.h:void      gtk_main_quit         (void);


					Happy Xmas ;-).
							Francois.
