From 6dce720dc64061352041f4a55c46590c8ffcc3a0 Mon Sep 17 00:00:00 2001
From: Christopher James Lahey <clahey@helixcode.com>
Date: Wed, 6 Dec 2000 18:38:39 +0000
Subject: Added gal-view-collection.c, gal-view-etable.c,
 gal-view-factory-etable.c,

2000-12-06  Christopher James Lahey  <clahey@helixcode.com>

	* Makefile.am: Added gal-view-collection.c, gal-view-etable.c,
	gal-view-factory-etable.c, gal-view-factory.c,
	gal-view-collection.h, gal-view-etable.h,
	gal-view-factory-etable.h, and gal-view-factory.h.

	* gal-define-views-dialog.c, gal-define-views-dialog.h: Rewrote
	this to take a GalViewCollection.  This now passes its collection
	to the new view dialog but still doesn't get its list of views
	from the collection.

	* gal-define-views-model.c: Changed this to use the gal_view_get_title
	function instead of the "title" gtk argument.

	* gal-define-views.glade, gal-define-views.glade.h: Changed this
	dialog to be a bit cleaner.

	* gal-view-collection.c, gal-view-collection.h: A collection of
	views and view factories.

	* gal-view-etable.c, gal-view-etable.h: An implementation of the
	view class.  This stores an ETableSpecification and the current
	ETableState.

	* gal-view-factory-etable.c, gal-view-factory-etable.h: An
	implementation of the view factory class.  This stores an
	ETableSpecification and creates GalViewEtables when requested.

	* gal-view-factory.c, gal-view-factory.h: A new virtual class.
	Its primary job is to return new GalViews.

	* gal-view-new-dialog.c, gal-view-new-dialog.h: Added a collection
	argument to the new function here so that it can get a list of
	factories to choose from.

	* gal-view-new-dialog.glade, gal-view-new-dialog.glade.h: Added a
	CList for the list of factories to choose from.

	* gal-view.c, gal-view.h: Changed this to be a virtual class.
