2002-05-27 Michael Natterer <mitch@gimp.org> * app/config/gimpconfig.[ch]: added "gint nest_level" to the deserialization functions, so nested calls to deserialize() don't error on the trailing ')'. Made the scanner config parse one-character identifiers and allow G_CSET_A_2_Z for all identifiers. Added gimp_config_deserialize_return() because returning the correct return value from a deserialize() function is not trivial any more with nested calls. * app/config/gimpconfig-deserialize.[ch] * app/config/gimprc.c * app/core/gimpdocumentlist.c * app/core/gimpparasitelist.c: use the new return value utility function and made the main parsing loops simpler. * app/core/gimpunits.c: made the main parsing loops consistent with the stuff that uses GimpConfig. * app/config/gimpconfig-deserialize.c * app/config/gimpconfig-serialize.c: call the (de)serialize_property() functions only if the property's class implements the method itself (does *not* inherit it from one of it's parents). * app/core/gimpcontainer.c: implemented deserialization of containers. For each child entry encountered in the input, check if it's already contained in the container and create it if not. If a "gimp" pointer is passed as user_data pass it as construct property to g_object_new() when creating the object. * app/core/gimpcontext.c: changed deserialization of brush, pattern etc. to honor "no_data". * app/widgets/gimpdeviceinfo.c: added a "gimp" construct_only property which overrides GimpContext's "gimp" property. Moved all initialisation code from gimp_device_info_new() to gimp_device_info_set_property(PROP_GIMP) so it is properly performed if the object is created by GimpContainer's deserialize() implementation. * app/widgets/gimpdevices.c: made gimp_devices_restore_test() work.
