* parser/Gnome.metadata, Gtk.metadata: More conflict fixes. * parser/build.pl: Fully qualify all lib names. (Gtk+ packages are now LFS-compliant in Debian...) * parser/gapi2xml.pl: Fix for whitespace in fields, defines, and docs. * generator/BoxedGen.cs: Remove extraneous CallByName definition, add "override" keyword to FromNative. (Generate): Generate methods after fields. * generator/ClassBase.cs: Change CallByName, FromNative to virtual. (.ctor): Ignore "hidden" nodes. Set container on signal. (GenSignals, GenMethods): Add "implementor" argument for interface use. (Get(Method|Signal|Property)Recursively): Rework to correctly recurse interfaces. (Implements): Added. * generator/Ctor.cs (Initialize): Move clash initialization completely out of Generate, so we can check for collisions. * generator/Method.cs (GenerateDeclCommon): Check for duplicates, for "new" keyword. (Generate): Add "implementor" argument. * generator/ObjectGen.cs (Generate): Initialize ctor clashes on this and all parents, before generating. (Ctors, InitializeCtors): Added. * generator/Signal.cs: Store the container_type, check for collisions. * generator/StructGen.cs: Add "override" keyword to overriden methods. * gtk/FileSelection.custom (ActionArea): Add "new" keyword. svn path=/trunk/gtk-sharp/; revision=5782
