* */*-api.xml: Regen, adding gtype="..." to many enum types * generator/EnumGen.cs (Generate): if the enum has the "gtype" property, add a GTypeAttribute pointing to an internal FooGType class whose GType property can be used to get the enum's GType. * generator/ObjectGen.cs: s/ObjectManager.RegisterType/GType.Register/ * glib/GTypeAttribute.cs: attribute for indicating a property that will return the GType of a type (particularly for enums, which can't have GType properties added to them). * glib/GType.cs: renamed from Type.cs to match the type name (public static readonly GType ...): add a few missing types. (Register): moved from ObjectManager.RegisterType (LookupGType): moved from TypeConverter.LookupType and extended to handle GTypeAttribute. Also, fix mappings for sbyte/byte/char, and return specific GTypes for Object subclasses rather than always returning GType.Object. [Fixes #74699] (LookupType): moved from ObjectWrapper.LookupType (ToString): return the type name * glib/Object.cs (RegisterGType): s/ObjectManager.Register/GType.Register/ (LookupGType): Make this protected internal so GType can access it. * glib/ObjectManager.cs (RegisterType): deprecate in favor of GType.Register. (LookupType): moved to GType * glib/TypeConverter.cs (LookupType): now a deprecated wrapper around GType.LookupGType. * glib/Value.cs: Use GType casts rather than TypeConverter * gtk/NodeStore.cs (ScanType): * gtk/ListStore.custom (ListStore): * gtk/TreeStore.custom (TreeStore): Use (GType) cast rather than TypeConverter. Remove the error check and exception, since the cast never returns GType.Invalid. (The check probably predates GLib.ManagedValue.) * gnome/PanelAppletFactory.cs (Register): Use a GType cast rather than GLib.Object.LookupGType (which is no longer accessible after an mcs bugfix) * sample/GtkDemo/DemoIconView.cs (CreateStore): use the Type[] constructor rather than the GType[] constructor, since it translates typeof(Gdk.Pixbuf) correctly now. svn path=/trunk/gtk-sharp/; revision=44038
