Re: [Vala] gtk widget bindings complete

[gege2061 <gege2061 redaction-developpez com>]

Complete GladeValaDemo class with :

public abstract void on_button1_clicked(Gtk.Widget widget);
public abstract void on_GladeValaDemo_destroy (Gtk.Widget widget);

The problem is to determine the prototype of callback :/
