I'm afraid I haven't used Glade recently enough to offer detailed 
advice, but I recall studying the generated code when creating this 
example:

<http://home.roadrunner.com/~jbmatthews/gtk/lady.html>

In this tutorial,

<http://www.micahcarrick.com/gtk-glade-tutorial-part-1.html>

the window destroy callback shown in C and Pyhton,

<http://www.micahcarrick.com/gtk-glade-tutorial-part-1.html#Specifying_Callback_Functions_for>

corresponds roughly to this line in procedure Init:

Void_Cb.Connect (Win, "destroy", Void_Cb.To_Marshaller (Quit'Access));

Hope this helps.
