Updating a statusbar widget

[Nicholas <mcmxc freemail gr>]

hi people

imagine the following lines:

-----------------------------------
int
main(arg--etc) {

 gtk_init (&argc, &argv);

     window --bla-bla--

/* i create a statusbar */

 status_bar = gtk_statusbar_new();
 gtk_box_pack_start (GTK_BOX (vbox), status_bar, TRUE, TRUE, 0);
 gtk_widget_show (status_bar);

 context_id = gtk_statusbar_get_context_id(
                    GTK_STATUSBAR(status_bar), "Statusbar example");


 sub_rout1();    // i call a subroutine

 gtk_widget_show (window);
 gtk_main ();
 return(0)

}

 void sub_rout1 {
    /* here is a loop */
    for (bla bla) {
        do smth;
        sub_rout2();
     }
 }

 void sub_rout2 {
    /* in here i'm trying to update the text in 'statusbar' widget */
     gtk_statusbar_push( GTK_STATUSBAR(status_bar), GPOINTER_TO_INT(data),
buff)
     return;
 }

--------------------------------------
Well it doesn't work... exept when it exits from the loop the
statusbar gets the last value.

Any way how to make the updated contents of the statusbar
visible while in the loop?

thanks
