GtkSharp/generator/Ctor.cs
Mike Kestner f61ac5c89c 2003-12-03 Mike Kestner <mkestner@speakeasy.net>
* generator/CallbackGen.cs : use new sig and isig classes.
	* generator/Ctor.cs : use new sig, isig, and body classes.
	* generator/ImportSignature.cs : isig code spun out from Parameters.
	* generator/Method.cs : use new sig, isig, and body classes.
	* generator/MethodBody.cs : spun Initialize, GetCallString,
	Finish, and Exception throwing methods from Parameters.
	* generator/Parameters.cs : Slayed the evilness that was CreateSignature.
	It is now essentially a container for Parameter classes instead of a
	tangled mess of code trying to do everything remotely related to
	parameter lists. Also completely killed the VAType/IsVarArgs stuff,
	as it can be done with the array and params attrs instead.
	* generator/Property.cs : use new sig class.
	* generator/Signature.cs : new method sig generator extracted from
	Parameters class. add "params" keyword support for tagged parameters.
	* gnome/Gnome.metadata : hide IconList.GetSearchPath (to be manual)
	* gnome/gnome-api.xml : regen
	* gtk/ListStore.custom : kill unneeded overload
	* gtk/TreeStore.custom : kill unneeded overload
	* gtk/Gtk.metadata : mark params/args on *store_newv
	* gtk/gtk-api.xml : regenerated
