dispose and finalize
Hi, what's the difference between dispose and finalize? And which members have to be freed in which of these functions? Thanks ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

See http://library.gnome.org/devel/gobject/unstable/gobject-memory.html The difference in short: dispose: - g_object_unref() all GObject member variables - function must be safe against being called multiple times finalize: - free all other (non-GObject) members, close file descriptors etc Holger ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
Re: dispose and finalize
OK Thanks, So if I have a Garray member, I call g_array_unref in finalize, because it isn't a child of GObject. Correct?

Actually, I would decrement the reference count of all reference counted objects in dispose. Speaking of GObject is probably an over-simplification. I am not sure if that's strictly required, but it sounds safer anyways. Holger ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Thanks In dispose you should drop all references to other GObjects. In finalize you free other data (char *, GArray *, etc.) dispose can be invoked more than one time before finalize. See also [1], specifically last section.
