2002-07-25 Rachel Hestilow <hestilow@ximian.com> [about 60% of the marshalling patch that I lost. The rest to come tomorrow.] * generator/BoxedGen.cs, StructGen.cs: Move most of this to StructBase, delete large chunks duplicated from ClassBase. * generator/IGeneratable.cs: Add MarshalReturnType, FromNativeReturn. * generator/ClassBase.cs: Move ctor stuff here. Add a CallByName overload with no parameters for the "self" reference. * generator/EnumGen.cs, CallbackGen.cs: Implement new MarshalReturnType, FromNativeReturn. * generator/Method.cs: Use container_type.MarshalType, CallByName, and SymbolTable.FromNativeReturn when generating call and import sigs. * generator/OpaqueGen.cs: Added. * generator/Property.cs: Handle boxed and opaques differently. * generator/SymbolTable.cs: Update for the opaque stuff and the new Return methods. Also change GetClassGen to simply call the as operator. * glib/Boxed.cs: Update for struct usage -- this is now a wrapper for the purposes of using with Value. * glib/Opaque.cs: Added. New base class for opaque structs. * glue/textiter.c, gtk/TextIter.custom: Remove. * gnome/Program.cs: Update for new struct marshalling. * parser/Metadata.pm: Use our own getChildrenByTagName. * parser/README: Update for new requirements (was out of sync with build.pl) * parser/gapi2xml.pl: Hide struct like const in field elements. * parser/gapi_pp.pl: Handle embedded union fields (poorly). * sample/test/TestColorSelection.cs: Comment out null color tests for now. svn path=/trunk/gtk-sharp/; revision=6186
