In the same way all GLib.Object-derived classes provided by the
generator have a GType static property (i.e. Gtk.Widget), we need
the same for the *Adapter classes, to access their GType without having
an instance of it. (The first use case would be GStreamerSharp's
Gst.Bin.IterateAllByInterface ().)
For this, we cannot simply add the property to all adapter classes
and be done, because it would clash with a property which is already
there, but is non-static, that has the same name and same value
(this property is needed for complying GInterfaceAdapter abstract
class), so we rename this property to GInterfaceGType because
using this name for the static one would not be consistent with the
rest of the classes generated which already provide the static one
with the name "GType".
To be able to do this, Name property of GenBase class is now virtual, so
that it can be overriden in InterfaceGen with the new name.
Adapters, however, are still classes and then need special care as such
(cannot use the 'Name' property anymore), but this improves a bit the
readability of some parts of the code as the *Implementor and *Adapter
suffixes are now concentrated in just two new properties of GenBase and
not repeated all over the place.
GObject upstream has started disabling support for installing interfaces
in GTypes after they have already been initialized (class_init) [1], so
we need to add GInterfaces a bit earlier (*before* class_init starts).
As GLib.Object.OverrideProperty() cannot to be called before class_init
(because it receives a GObjectClass, not a GType) or after (because
otherwise class_init would complain about properties of an interface not
being defined), then we need to call it during class_init.

A good side-effect of this fix is that we no longer use the hacky uint
field 'idx' to track the properties count for each class; now it gets
moved to the ClassInitializer class, and thus can be non-static, which
makes a bit more sense (we leave the old OverrideProperty overload for
backwards compatibility).
Simplest way to test this is launching the sample/treemodeldemo.exe and
sample/custom-scrollable.exe in Ubuntu 13.04 beta (which has GLib 2.36).

Don't generate a static field if it's not going to be used.
This fixes a compilation warning on the generated code for interfaces
that don't have virtual methods.
GInterfaceInfo.Data was automatically set to be a GCHandle on the
interface adapter. But the generated GInterfaceInitHandlers were
not using it, just free'ing it.
But for the GInterface property support, the Data field is now used to
pass the class pointer, so casting it to a GCHandle to free it would
cause an exception.
We now don't assume anything about GInterfaceInfo.Data.
Switch the hash tables used to store fields, properties and methods to
strong-type dictionaries, and make them private. Make the necessary
adjustments in the subclasses.
The additional type information makes the code a bit more safe
and readable.
At least one bug is fixed by this: in ObjectGen, an invalid child
property could still be generated, as it was not removed from the hash
table.
This should cause no real change to the generated code, except maybe in
the order of some members.
In a lot of places, we were only checking the presence of boolean
attributes, like "array", automatically assuming they were true. This
meant that we didn't allow setting them explicitly to false, which
apparently is needed for some bindings.
For all boolean attributes, we now use the GetAttributeAsBoolean method
added in the previous commit, to correctly check the value of the
attribute. As before, if the attribute is not present, it is considered
to be false.
Thanks to Stephan Sundermann for noticing this issue.
* generator/*.cs: Add a LogWriter class which formats warnings
consistently on the console. Supports the concept of non-fatal
validation warnings, since it doesn't rely on the unrolling of the
validation stack to associate a warning to a given type.
Main purpose was to add a non-fatal warning for missing element_type
attributes on list return values, though it results in cleaner log
output, and also updates some warning messages to be more helpful in
how to resolve them.
* generator/InterfaceGen.cs: don't grab the StreamWriter for consume-only.
* generator/InterfaceVM.cs: don't bitch or fail validation when missing
target on consume-only.
* generator/ObjectBase.cs: support a target_method attr on vms to point the
callback invocations at when the names don't match.
* gio/Gio.metadata: marks a few more ifaces consume-only until somebody
complains they need to implement one of them.
* generator/InterfaceGen.cs: remove var keyword usage to fix build on
.Net 2.0. fix a couple mixed line endings as well.
svn path=/trunk/gtk-sharp/; revision=139109
* generator/GenBase.cs: Add AppendCustom override that you can pass the
type name in, used to include .custom for Name + Adapter and Name +
Implementor .custom files for interface gen.
* generator/InterfaceGen.cs: Use the new AppendCustom override for the
Name + Adapter.custom file, and add support for including custom file for
the Name + Implementor interface; necessary to manually implement an
interface method.

* generator/ClassField.cs: Derive from StructField.
* generator/ObjectBase.cs: Implement validation mechanism for
class structures. If the structure contains bitfields or fields
of unknown types, we cannot generate it in managed code.
* generator/GObjectVM.cs: Fall back to glue if the class structure
cannot be generated. [Fixes#498051]
svn path=/trunk/gtk-sharp/; revision=133514
Add support for virtual methods(vm) to the generator.
* parser/gapi2xml.pl: Generate a class_struct element with
all members of the class structure. Dump the first (instance)
parameter for signal and vm elements. Bump up parser version.
* generator/GObjectVM.cs: Added. Support for GObject virtual methods.
* generator/DefaultSignalHandler.cs: Signal specific part of vm
generation.
* generator/InterfaceVM.cs: New class for interface vms.
* generator/ObjectBase.cs: Parse the class struct.
svn path=/trunk/gtk-sharp/; revision=131604
* generator/InterfaceGen.cs: generate Adapters for consume_only ifaces
too. This seems unusual, but is primarily to produce at least one
'generic' implementation of every interface and a GetObject method
so that the marshaling code can always return an object which
implements the interface, even if no public object wrapper exists for
the underlying c GObject type.
svn path=/trunk/gtk-sharp/; revision=122814
* generator/InterfaceGen.cs: use the new GLib API to detect
instances that don't implement GInterfaces.
* glib/GType.cs: add new API for checking if an IntPtr instance
implements a certain GType.

* generator/InterfaceGen.cs: use CName and mangle it. ClassFieldName
is not guaranteed to be set now.
* generator/Signal.cs: read ClassFieldName from the api xml. Move
glue writer lookup inside the block to avoid exceptions for now.
svn path=/trunk/gtk-sharp/; revision=102276
* generator/InterfaceGen.cs:
* generator/Signal.cs: use generic signal marshaling instead of
generating signature specific marshaling callbacks.
* glib/glue/closure.c: glue for new closure impl.

* glib/Signal.cs: hook in closure based connection and expose
EmissionHook functionality for atk usage.
* glib/SignalClosure.cs: new generic signal marshaling mechanism.
* glib/ToggleRef.cs: null guarding in Target and let Signal remove
itself from hash when it disposes itself.
svn path=/trunk/gtk-sharp/; revision=102241
* generator/InterfaceGen.cs: support "generic" interface
implementations like those exposed by gio. This is specifically for
libraries which return GTypes which are not exposed by the library
but which implement GInterfaces which are exposed by the library.
svn path=/trunk/gtk-sharp/; revision=99541
* generator/*.cs: implement the interfaces on the adapters too.
Generate an Implementor interface for users which exposes the
methods to implement. Register based on the Implementor sub-iface.

interface members.
* gtk/TreeIter.custom: make UserData public.
* sample/TreeModelDemo.cs: sample for implementing a TreeModel
interface.

with persistence of native and wrapper delegates in native to managed
callback method signatures.
* generator/VirtualMethod.cs: support for generation of interface
methods, and all the funky parameters that come with that.
* generator/InterfaceGen.cs: Fill out the adapter implementation.

to support GError outside the last parameter slot.
* glib/GInterfaceAttribute.cs: New attribute to mark interfaces and
obtain adapter type.

parent class and interfaces (because we don't want to see the
warnings about certain GtkWidget methods in every single library
that defines a widget, etc). Instead, use the new
ValidateForSubclass() method.
(ValidateForSubclass): only validate the signals

we need to validate the methods too.

properties can't be set until Validate-time (eg, Method.IsGetter),
but it's annoying for every potential user of those properties to
have to make sure it has Validated the generatable first. So now
we add an explicit Validate() step after everything is loaded but
before anything is Generated, so that at Generation time,
everything can be assumed to have been Validated.
* generator/IGeneratable.cs: add "bool Validate()"
* generator/CodeGenerator.cs (Main): after loading all of the
generatables, DeAlias the SymbolTable, Validate() all the
generatables, and discard any invalid ones.
* generator/*.cs: Implement Validate() trivially in generatables
that didn't implement it before. Move Validate() calls from
Generate() to Validate(). Remove non-hierarchical Validate()
calls.
* generator/SymbolTable.cs: GPtrArray is IntPtr, not IntPtr[]
svn path=/trunk/gtk-sharp/; revision=48046

* gtk/gtk-api-2.4.raw:
* gtk/gtk-api-2.6.raw: Regen (adding properties to GtkFileChooser).
* generator/Property.cs (GenerateDecl): new method to generate
just a property declaration (for an interface).
(Generate): Add an "implementor" arg as with Method.Generate.
* generator/InterfaceGen.cs (Generate): Generate properties. Also,
validate methods *before* checking if they should be ignored,
since certain Method properties aren't set until Validate-time.
* generator/*.cs: misc minor changes/reorg for the above.
