 Here is a code snipet that does this. (It changes only the label though --
should not be difficult to add code to change the icon.)

static GtkToolbarChild* child;  /* used to change the Start/Stop button label*/

/**
 * Find the GtkToolbar child once the server stars runnning. (The label is
"Start" at the beginning. and sets the static var "child" to poit to it.
 */

static void init_toolbar_child(GtkToolbar* toolbar)
{
    GList* list = NULL;
    g_return_if_fail(toolbar != NULL);
    list = toolbar->children;
    while( (child = (GtkToolbarChild*)(g_list_next(list))->data))
    {
        if(child->label != NULL)
        {
            if(!strcmp("Start", gtk_label_get_text(GTK_LABEL(child->label))))
            {
                break;  /* found */
            }
        }
    }
}

  On the above code, all I am doing it trying to get the "child"
(GtkToolBarChild that relateds to my button on the toolbar..


 In some callback the code. ( CLICK BUTTON EVENT on the toolbar ) I do:
 
  if(gtk_toggle_button_get_active(togglebutton))  
    {
           ...
        statusbar = lookup_widget(GTK_WIDGET(togglebutton) , "statusbar1");    
  
        gtk_label_set_text(GTK_LABEL(child->label), "Stop");
        stop_timeout_call = TRUE;
    }
    else
    {
        gtk_label_set_text(GTK_LABEL(child->label), "Start");
        stop_timeout_call = FALSE;
    }


  All the code above does is: IF the Label of the button was "Start", change it
to "Stop" or if it was "Stop" change it to "Start"

  
  To figure this out, I had to look at the gtktoolbar.c 

  Hope this helps.

Harring.
