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

* parser/gapi2xml.pl (addFuncElems): if a struct or boxed type has a constructor or a ref, unref, or destroy method, then it must be a reference type, so mark it "opaque" but then also mark all of its fields public and writable. * */*-api*.raw: Regen * generator/Parser.cs (ParseNamespace): make the opaque attribute check actually look at the value of the attribute rather than just checking if it's there, so that you can change a struct's opaque attribute from "true" to "false" via metadata and have that work. * generator/BoxedGen.cs (Generate): do not generate the boxed's "Free" method (since it's guaranteed to crash when we pass it a stack pointer). If "Copy" is marked deprecated, create a deprecated no-op for it, otherwise just skip it (since otherwise it will just leak memory when we copy its result onto the stack). * pango/Pango.metadata: deprecate Pango.Color.Copy and Pango.Matrix.Copy. Hide some array fields in Pango.GlyphString that we've never generated correctly. Tweak Pango.LayoutLine fields to be the same as they used to be. * pango/GlyphItem.custom (glyphs, item): * pango/GlyphString.custom (Zero, New): * pango/Item.custom (Zero, New): * pango/LayoutRun.custom (glyphs, item): add deprecated API compat * gdk/Gdk.metadata: undo the parser's new opaquification of Gdk.Font; it's been deprecated since pre-gtk# times, and no one should be using it, so there's no point in fixing it now. Fix up a few other things to match how they used to be. Fix RgbCmap's constructor args. * gdk/RgbCmap.custom (Zero, New): deprecated API compat * gdk/PangoAttrEmbossed.custom: * gdk/PangoAttrStipple.custom (Zero, New, Attr): deprecated API compat (explicit operator ...): allow casting back and forth between Pango.Attribute. (We can't usefully make them real subclasses of Pango.Attribute, because there's no way for Pango.Attribute.GetAttribute() to be able to dtrt with them.) * gtk/Gtk.metadata: deprecate Gtk.Requisition.Copy, Gtk.TextIter.Copy, and Gtk.TreeIter.Copy. Mark the return value of TextView.DefaultAttributes as "owned". Mark TargetList's fields private so it stays how it used to be. * gtk/TextAttributes.custom (Zero, New): deprecated API compat * gnomevfs/Gnomevfs.metadata: remove a bunch of opaque declarations that the parser figures out on its own now. * art/Art.metadata: * glade/Glade.metadata: * rsvg/Rsvg.metadata: un-mark everything the parser marked opaque in these libraries, because all of the structs in question would still be unusably broken, so the API churn would be pointless. svn path=/trunk/gtk-sharp/; revision=48387
