Integrate Erwann Chenede's multihead changes for the gtk/ directory.

Mon Apr 29 18:28:00 2002  Owen Taylor  <otaylor@redhat.com>

	Integrate Erwann Chenede's multihead changes for the gtk/ directory.

	* gtk/gtkclipboard.[ch]: Add gtk_clipboard_get_for_display(),
	make internals multihead aware.

	* gtk/gtkcolorsel.[ch]: Add
	gtk_color_selection_set_change_palette_with_screen_hook () [ugh!]
	make up for non-multihead safety of
	gtk_color_selection_set_change_palette_hook()

	* gtk/gtkinvisible.[ch] gtk/gtkmenu.[ch] gtkwindow.[ch]: Add
	gtk_{invisible,menu,window}_set_screen(); add "screen" properties
	for GtkWindow and GtkMenu.

	* gtk/gtkplug.[ch]: Add gtk_plug_construct_for_display(),
	gtk_plug_new_for_display(). Multihead fixes.

	* gtk/gtkselection.[ch]: Add gtk_selection_owner_set_for_display(),
	make internals multihead aware.

	* gtk/gtksettings.[ch]: Add gtk_settings_get_for_screen(), get
	rid of now-useless gtk_settings_constructor().

	* gtk/gtkstyle.[ch]: Add gtk_style_get_font_for_display(), fix
	check/radio button indicators bitmap handling to be multihead
	safe.

	* gtk/gtkwidget.[ch]: Add gtk_widget_get_screen(), gtk_widget_has_screen(),
	gtk_widget_get_display(), gtk_widget_get_clipboard(),
	gtk_widget_get_root_window().

	* gtk/gtkbindings.c gtk/gtkbutton.c gtk/gtkclist.c gtk/gtkcombo.c
	gtk/gtkctree.c gtk/gtkdnd.c gtk/gtkfilesel.c gtk/gtkgamma.c
	gtk/gtkhandlebox.c gtk/gtkhsv.c gtk/gtkimcontext.c gtk/gtklabel.c
	gtk/gtklist.c gtk/gtkmain.c gtk/gtkmenuitem.c gtk/gtkmenushell.c
	gtk/gtknotebook.c gtk/gtkoldeditable.c gtk/gtkoptionmenu.c
	gtk/gtkpaned.c gtk/gtkpreview.c gtk/gtksocket.c gtk/gtktext.c
	gtk/gtktextbuffer.c gtk/gtktextview.c gtk/gtktipsquery.c
	gtk/gtktooltips.c gtk/gtktreeview.c gtk/gtktreeviewcolumn.c:
	misc mechanical multihead-safety fixes.

	* gtk/gtkclipboard.c: Use a GtkImage rather than a pixmap for
	the dropper, look up the color palette only at realization time,
	other multihead fixes.

	* gtk/gtkcombo.c (gtk_combo_unrealize): Popdown the list when
	unrealizing.

	* gtk/gtkentry.c: Only claim ownership of the primary selection
	when realized, misc multihead fixes.

	* gtk/gtkfontsel.c: Only fill in fonts when attached to a screen,
	fix gtk_font_selection_get_font() for multihead.

	* gtk/gtkgc.c: make the depth => drawable hash per-screen.

	* gtk/gtkinvisible.c: Add a constructor that realizes the
	widget, so we get a realized widget with g_object_new() as
	well gtk_invisible_new() as before.

	* gtk/gtkmain.c: Get rid of unused gtk_visual/gtk_colormap
	variables.

	* gtk/gtktextdisplay.c: Add warnings if stipple bitmaps
	are used on the wrong screen.

	* gtk/gtktoolbar.c: Make handling of GtkSettings-based layout
	read properties and connect to settings when the screen is changed,
	rather than on init/finalize.

	* gtk/gtkwindow.c: Fix icon handing to be multihead safe ...
	default icon pixmaps/mask are only shared between windows on the
	same screen. Misc multihead fixes.

Sat Apr 27 13:49:53 2002  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkclipboard.c (gtk_clipboard_get_for_display):
	Update docs to reference GDK_SELECTION_CLIPBOARD rather GDK_NONE.

2002-04-29  Alex Larsson  <alexl@redhat.com>

	* gdk/linux-fb/gdkproperty-fb.c (gdk_property_get):
	Fix silly bug, noticed by Sven Neumann.

Sun Apr 28 22:43:55 2002  Jonathan Blandford  <jrb@gnome.org>

	* gtk/gtktreemodelsort.c (gtk_tree_model_sort_set_sort_func): Fix
	so that you can set a new sort func.
