2004-02-05 Michael Natterer <mitch@gimp.org> Disallow editing of data objects which have no save functionality. Also fixed the misassumption that "deletable" is always equal to "writable". Fixes bug #133456. * app/core/gimpdata.[ch]: added a "deletable" property which is always equal to "writable" except when the data class does not implement GimpData::save() (then deletable may be TRUE but writable is always FALSE). * app/gui/brushes-menu.c * app/gui/gradients-menu.c * app/gui/palettes-menu.c * app/gui/patterns-menu.c * app/widgets/gimpdatafactoryview.c: look at data->deletable when setting the sensitivity of the "Delete" buttons and menu items. * app/widgets/gimpdatafactoryview.c (gimp_data_factory_view_tree_name_edited): rename the data only if it's writable and restore the old name otherwise. * app/widgets/gimpdataeditor.c: no need to look at data->internal for figuring if the data is editable, data->editable is enough. All files above: s/writeable/writable/g * app/widgets/gimpbrusheditor.c (gimp_brush_editor_set_data): simplified.
