Subject: GtkAda callback and event

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
