2002-12-02 Michael Natterer <mitch@gimp.org> * app/core/gimpdata.[ch]: use GError for reporting load/save errors. Added gimp_data_error_quark() and a GimpDataError enum. Made simple virtual functions out of save(), get_extension() and duplicate() because they don't need to be signals. * app/core/gimpbrush.[ch] * app/core/gimpbrushgenerated.[ch] * app/core/gimpbrushpipe.[ch] * app/core/gimpgradient.[ch] * app/core/gimppalette.[ch] * app/core/gimppattern.[ch]: changed accordingly. Set data->dirty to FALSE in each _load() function. * app/core/gimpdatafactory.[ch]: report GError messages here. Changed the ugly factory->path pointer location hack to factory->path_property_name and get the path from factory->gimp->config. Added gimp_data_factory_data_duplicate() implementation which was already declared in the header. * app/core/gimp.c: pass the path property name to gimp_data_factory_new(). * app/widgets/gimpdatafactoryview.c: removed the duplicate implementation and call gimp_data_factory_data_duplicate(). * app/core/gimpgradient.[ch]: added gimp_gradient_save_as_pov(). * app/gui/gradients-commands.c: removed save_as_pov implementation and call gimp_gradient_save_as_pov().
