Re: On_Button_Press_Event in Text_View

I have a custom handler used when I update the Text_Buffer:

 That works fine so I was imagining something similar might
be possible, but I've run through various permuations of
records and access types but not yet got a working callback.
 Any help gratefully received (I can post the full code if
that's useful).

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
    );
