* generator/CallbackGen.cs: the new generated wrappers have: -(optional) Field of the same type returned by the callback. -A call to RemoveIfNotAlive at the beginning. It returns true, return the dummy field. -Added an object to the ctor signature and pass it to the base class. * generator/Ctor.cs: added a Params property. * generator/Method.cs: set Static property in Parameters if the method is static. * generator/Parameters.cs: added Static property. The call creation of the delegate wrapper (if applicable) uses the new signature. Pass a null as object is the method is static. * generator/StructBase.cs: set Static for the parameters of the ctors. * glib/DelegateWrapper.cs: the ctor takes an object (the one creating the wrapper or null) and creates a weak reference to it. Store it in a static Hashtable (this way the wrapper itself is not garbage collected). (RemoveIfNotAlive): called from the native delegate callbacks. If the target of the weak reference has been garbage collected, removes itself from the hashtable to let the GC dispose this instance and returns true. * gdk/Pixbuf.custom: * gtk/Clipboard.custom: * gtk/GtkSharp.GtkClipboardClearFuncNative.cs: * gtk/GtkSharp.GtkClipboardGetFuncNative.cs: * glade/XML.custom: changed delegate wrappers to match the new signature. svn path=/trunk/gtk-sharp/; revision=13237
