Hi,

I use an event callback with user data.

I first declare a package :
    package Handler_Motion_Notify is new 
Gtk.Handlers.User_Return_Callback (Widget_Type => 
Gtk.Text_View.Gtk_Text_View_Record,
 
    Return_Type => Boolean,
 
    User_Type   => t_Debug_Panel);

The function callback is declared like this :
    function On_Motion_Notify (TextView : access 
Gtk.Text_View.Gtk_Text_View_Record'Class;
                               DebugPanel : t_Debug_Panel) return Boolean;

The connection is done like this :
       Handler_Motion_Notify.Connect (Widget => Panel.TextView,
                                      Name   => 
Gtk.Widget.Signal_Motion_Notify_Event,
                                      Cb     => On_Motion_Notify'Access,
                                      User_Data => t_Debug_Panel(Panel));

This works correctly. But... I need to have access to the event in the 
callback function.
How can I achieve this ?

Regards,
Nicolas
