Havoc Pennington e8597130f5 Move more text widget headers into the private header list
2000-09-26  Havoc Pennington  <hp@redhat.com>

	* gtk/Makefile.am (gtk_private_h_sources): Move more text widget
	headers	into the private header list

	* Makefile.am (pkgconfig_DATA): install pkg-config files

	* configure.in: add pkg-config files

	* gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files

	* gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate
	outstanding icon caches on theme change.

	* gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three
	important types:

	(GtkIconSource): Specification for creating a pixbuf
	appropriate for a direction/state/size triplet from
	a source pixbuf or filename

	(GtkIconSet): List of GtkIconSource objects that are used to
	create the "same" icon (e.g. an OK button icon), and cache for
	rendered icons

	(GtkIconFactory): Hash from stock ID to GtkIconSet; used to look
	up the icon set for a given stock ID.  GTK maintains a stack of
	GtkIconFactory to search, and applications or libraries can add
	additional icon factories on top of the stack

        * gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse
	the set of GtkIconSource specified for a given stock ID into
	a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the
	RcStyle, under the specified stock ID.

	* gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function
	render_icon used to derive a GdkPixbuf from a GtkIconSource.
	This allows people to theme how prelight, insensitive, etc. are
	done.

	(gtk_style_lookup_icon_set): Look up a stock ID in the list of
	icon factories for a style, and return the resulting
	icon set if any.

	(gtk_style_render_icon): Render an icon using the render_icon
	method in the GtkStyleClass.

	* gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon):
	Use the style for a given widget to look up a stock ID, get the
	icon set, and render an icon using the render_icon method
	of the style

	* gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type
	(contains information about a stock item), the built-in stock item
	IDs, and functions to add/lookup stock items.

	* gtk/stock-icons/*: Stock icons that come with GTK

	* gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns
	a button based on a GtkStockItem
	(gtk_button_new_accel): Takes a uline string and accel group, and
	installs the accelerator.

	* gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic
	image-display widget.
