end with "callback, gpointer, GDestroyNotify", then mark the callback as having "notified" Scope. (Parameters.IsHidden): Hide user_data and GDestroyNotify after a callback. (Parameter.Scope): make this settable (Parameter.IsDestroyNotify): new test * generator/MethodBody.cs (Initialize): Handle "notified" callback scope (using a GCHandle and GLib.DestroyHelper.NotifyHandler) * generator/CallbackGen.cs (GenWrapper): Add a static "GetManagedDelegate" method to the wrapper type, to translate a native delegate back to its corresponding managed delegate. (FromNative): use GetManagedDelegate. * generator/ReturnValue.cs (Validate): We handle callback return values now * generator/SymbolTable.cs: marshal GDestroyNotify as GLib.DestroyNotify * glib/DestroyNotify.cs: Moved from gtk * gtk/Gtk.metadata: globally change GtkDestroyNotify to GDestroyNotify, but then change back the ones that are exposed in the API. Un-hide lots of methods we can correctly autogenerate now. * gtk/DestroyHelper.cs: moved to glib * gtk/*.custom: remove methods that are autogenerated now, add Obsolete wrappers where needed, replace Gtk.DestroyHelper usage with GLib.DestroyHelper. * gdk/Gdk.metadata: * gnome/Gnome.metadata: Turn Gdk.Drawable.SetData and Gnome.IconList.SetIconDataFull's GDestroyNotify args into gpointers so the generated API stays the same as it used to be. * rsvg/Handle.custom: implement deprecated SetSizeCallback * sample/GtkDemo/DemoIconView.cs (CreateSort): update for API changes svn path=/trunk/gtk-sharp/; revision=44020
