[gtkada] how to get the Toplevel Window of a Menu_Item ?

[Thomas De Contes]

hi :-)

how to get the Toplevel Window of a Menu_Item ?

for other Widgets i use Get_Toplevel,
but for Menu_Items, if i try sth like "myWindow(Get_Toplevel(Object))" 
i get "CONSTRAINT_ERROR : tag check failed"
(i need it to access fields that i have added to Gtk_Window via 
myWindow)
