I've got it :) but IT WORKS PROPERLY

here are parts of my code:

   GtkWidget *button, *loop_button;
...
loop_button = gtk_toggle_button_new_with_label("Loop");
gtk_table_attach_defaults(GTK_TABLE(table),
                        loop_button,
                        5,6,
                        2,3);
    gtk_signal_connect (GTK_OBJECT (loop_button), "clicked",
                GTK_SIGNAL_FUNC (loop), GTK_OBJECT (drawing_area));
    gtk_widget_show (loop_button);
...
    button = gtk_button_new_with_label("Quit");
gtk_table_attach_defaults(GTK_TABLE(table),
                        button,
                        9,10,
                        2,3);
    gtk_signal_connect_object (GTK_OBJECT (button), "clicked",
                GTK_SIGNAL_FUNC (quit), GTK_OBJECT(loop_button));
    gtk_widget_show (button);
...
void quit(GtkObject *widget)
{
gtk_main_quit();
gtk_toggle_button_set_active(GTK_TOGGLE_BUTTON(widget),FALSE);
}

explanations
 I use 'button' many times, 'loop_button' only once. I need my program
exiting just after pressing "Quit" button, it works only if "Loop" button
is not toggled (I think that's because "loop" function have many things to 
do:), so I want my Quit buton to untoggle loop_button ("loop" function
works while(GTK_TOGGLE_BUTTON (widget)->active)) and then I want to
gtk_main_quit BUT I had to swap this actions, 'cos another way I get many
Gtk/Gdk 'messages' after exiting.
