[gtkada] Changes in GtkAda 2.24

Luckily, I found another way to obtain an event, which is cleaner too:
   Widget_Callback.Connect(Get_List(Oct_Combo), 
     "select-child", On_Select_Child_Event'Access);

>I do encourage you to migrate to the new gtk_combo_box, indeed, since gtk_combo has completely disappeared now in gtk+-3.

Yeah that's too bad! I also regret the removal of gtk_option_menu. Because you can set tooltips on each individual choice
which you can't with Gtk.Combo_Box.

>Opening bugs with the gtk+ developers is indeed the way to go (though I suspect they will not look at bugs against gtk+ 2.x, only gtk+ 3.x)

Good tip, thanks.
