Something like this:
package Event_Handlers is
new Gtk.Handlers.User_Return_Callback
( GObject_Record,
Boolean,
User_Data_Type
);
function On_Button_Press
( Object : access GObject_Record'Class;
Event : Gdk_Event;
Data : User_Data_Type
) return Boolean;
View.Set_Events (View.Get_Events or Button_Press_Mask);
Event_Handlers.Connect
( View,
"button-press-event",
Event_Handlers.To_Marshaller (On_Button_Press'Access),
Data
);
