2002-07-30 Rachel Hestilow <hestilow@ximian.com> * generator/ClassBase.cs: Change hasDefaultConstructor to protected, adjust now that it is an attr and not a subnode. Also add virtual property AssignToName (for ctors). * generator/Ctor.cs: Add property ForceStatic. (Generate): Optimize return code a bit for the static case. * generator/Method.cs: Assign to a "raw_ret" pointer before calling FromNativeReturn. * generator/Parameters.cs: Change "out ref" to "out", not "ref". * generator/Property.cs: Fix to work correctly with all object and struct types (mostly just some if-cases added). * generator/SignalHandler.cs: Remove args_type and argfields (unused). (Generate): Initialize struct if necessary. * generator/StructBase.cs: Massive reworking to support methods, ctors, etc. * generator/SymbolTable.cs: Add GdkAtom and gconstpointer simple types. * glib/Boxed.cs: Accept both IntPtr and object ctors. Add access for both. * glib/Opaque.cs: Fix copy/pasted copyright notice, remove data and event fields. Fix docs. * glib/Value.cs: Work correctly with boxed properties. * gnome/Modules.cs: Use new struct ctors. * gnome/Program.custom: Remove Get, this is being generated now. * parser/Gdk.metadata: Fix the drawable classes to inherit correctly. * parser/Metadata.pm: Change per-class attributes to actually be attributes. * parser/Gtk.metadata: Add a dummy attribute value for disabledefaultctor. * parser/gapi2xml.pl: Add hacks for the (broken) Drawable and Bitmap typedefs. * sample/test/TestColorSelection.cs: Display color string in hex format, update to use IsNull instead of == null, and size dialog to look pretty. * sample/Size.cs: Added. svn path=/trunk/gtk-sharp/; revision=6264

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
