Dodji, that works fine. 

However, instead of doing :
	gtk_container_add (GTK_CONTAINER (applet),
		GTK_WIDGET (label->gobj ()));

since PanelApplet is child of GtkEventBox (from gnome-panel docs) why
can't I do :

    Gtk::EventBox gtkmmApplet = static_cast<Gtk::EventBox> (*applet);
    gtkmmApplet.add (*panelLabel);

BTW, I get this error: no matching function for call to
'Gtk::EventBox::EventBox (_PanelApplet &)'


Thank,
