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

Ignore "_" functions here. * parser/gapi_pp.pl: Remove boxed_type_register check, as it will be caught in the init funcs. * parser/Atk.metadata: Added. * parser/Gtk.metadata: Add all needed signal/method collision renames. Rename GtkEditable.Editable accessors to IsEditable, as .NET does not like accessors with the same name as their declaring type.
