gtkmm-main lists sourceforge net 

but this is a GTK level question, even if the code itself is Gtk--.

Repeating myself again: please don't do this. Use 

	  status_lbl1->set_name ("StatusLabel");
	  status_lbl2->set_name ("StatusLabel");

and then load a GTK RC file with:

    style "status_label" {
        fg[NORMAL] = { 0.93, 0.94, 0.23 }
    }
    widget "*StatusLabel" style "status_label"

this allows and your users to change the colors at run time without
any recompilation. as a side effect, it also removes a bunch of ugly
code from your app :)
