Owen Taylor 1bbf2ac7ee Make gdkx.h the only installed header from gdk/x11. All structures in 
Fri Sep  7 11:51:44 2001  Owen Taylor  <otaylor@redhat.com>

      Make gdkx.h the only installed header from gdk/x11.
      All structures in gdk/x11 are opaque.

	* gdk/x11/Makefile.am gdk/x11/gdkx.h gdk/x11/gdkprivate-x11.h:
	Don't install gdk{drawable,pixmap,window}-x11.h.

	* gdk/x11/{gdkcolormap-x11.c, gdkfont-x11.c, gdkx.h, gdkvisual-x11.c:
	Move GdkColormapPrivateX11, GdkFontPrivateX GdkImagePrivateX11,
	GdkVisualClass into C files.

	* gdk/gdkpixmap-x11.[ch]: Make gdk_pixmap_impl_get_type() static.

	* gdk/x11/{gdkcolor-x11.c, gdkcursor-x11.c, gdkdrawable-x11.c,
	gdkfont-x11.c, gdkgc-x11.c, gdkx.h, gdkimage-x11,gdkvisual-x11.c}
	Add public functions to replace previously exported direct
	structure access.
	gdk_x11_colormap_get_{xdisplay,xcolormap}
	gdk_x11_cursor_get_{xdisplay,xcursor},
	gdk_x11_drawable_get_{xdisplay,xcursor,gdk_x11_visual_get_xvisual,
	gdk_x11_font_get_{xdisplay,xfont}, gdk_x11_image_get_{xdisplay,ximage},
	gdk_x11_gc_get_{xdisplay,ximage}

	* gdk/gdkprivate.h gdk/gdkinternals.h: Move GdkColorInfo,
	GdkEventFilter, GdkClientFilter, GdkFontPrivate to gdkinternals.

      Fix a number of variables and functions that were exported
      "accidentally" from GDK.

	* gdk/**.[ch]: gdk => _gdk for gdk_visual_init,
	gdk_events_init, gdk_input_init, gdk_dnd_init, gdk_image_exit,
	gdk_input_exit,	gdk_windowing_exit, gdk_event_func, gdk_event_data,
	gdk_event_notify, gdk_queued_events, gdk_queued_tail,
	gdk_event_new, gdk_events_queue, gdk_events_unqueue,
	gdk_event_queue_find_first, gdk_event_queue_remove_link,
	gdk_event_queue_append, gdk_event_button_generate,
	gdk_debug_flags, gdk_default_filters, gdk_parent_root.

	* gdk/x11/{gdkevents-x11.c, gdkglobals-x11.c, gdkimage-x11.c,
	   gdkmain-x11.c, gdkprivate-x11.h, gdk/x11/gdkwindow-x11.c}:
	gdk => _gdk for gdk_event_mask_table, gkd_nevent_masks,
	gdk_wm_window_protocols, gdk_leader_window, gdk_xgrab_window,
	gdk_use_xshm, gdk_input_ignore_core.

	* gdk/x11/xsettings-common.h (xsettings_list_insert): Add
	#defines to namespace functions into the private _gdk_
	namespace.

	* gdk/gdkwindow.[ch] gdk/x11/gdkx.h: Add gdk_get_default_root_window ()
	to replace gdk_parent_root exported variable. Adjust and
	deprecate GDK_ROOT_PARENT().

	* demos/{testpixbuf-drawable.c,testpixbuf-save.c}: Fix
	GDK_ROOT_PARENT usage, remove includes of port-specific
	headers.

	* gdk/{win32,x11,fb}/gdkinput*.[ch]: s/gdk/_gdk/ for
	_gdk_input_gxid_host, _gdk_input_gxid_port, _gdk_input_ignore_core,
	gdk_input_devices, _gdk_input_windows, gdk_init_input_core.

	* gdk/x11/{gdkevents-x11.,c gdkglobals-x11.c, gdkmain-x11.c}
	docs/Changes-2.0.txt: Remove gdk_wm_protocols,
	gdk_wm_delete_window functions, gdk_wm_take_focus,
	use gdk_atom_intern() instead.

	* gdk/linux-fb/{gdkselection-fb.c, gdkmain-fb.c, gdkprivatefb.h}
	  gdk/win32/{gdkselection-win32.c, gdkmgdkwin32.h, gdkprivate-win32.h}
	  gdk/x11/{gdkselection-x11.c gdkx.h, gtkprivate-x11.h}
	  gtk/gtkselection.c
        Unexport gdk_selection_property, just use
	gdk_atom_intern ("GDK_SELECTION").

	* gdk/x11/{gdkprivate-x11.h,gdkdrawable-x11h,gdkgc-x11.c,gdkx.h}:
	Unexport gdk_drawable_impl_x11_get_type, gdk_gc_x11_get_type,
	GDK_GC_X11 cast macros, GdkGCX11 structures, GdkCursorPrivate,
	GdkVisualprivate, gdk_x11_gc_flush.

      Make a number of public exports of variables into functions
      to increase encapsulation.

	* gdk/gdkinternals.h gdk/gdkinput.h gdk/gdkevents.h
	gdk/linux-fb/gdkmouse-fb.c: gdk_core_pointer => _gdk_core_pointer,
	move to gdkinternals.h. Add gdk_device_get_core_pointer ().

	* gdk/gdkprivate.h gdk/gdkpango.c gdk/gdkinternals.h
	docs/Changes-2.0.txt: Unexport gdk_parent_root, gdk_error_code,
	gdk_error_warnings.

	* gdk/x11/{gdkcolormap-x11.c, gdkmain-x11.c, gdkx.h}
	  docs/Changes-2.0.txt:
	s/gdk_screen/_gdk_screen/, add gdk_x11_get_default_screen()
	s/gdk_root_window/_gdk_root_window/, add gdk_x11_get_default_root_xwindow()
	Add gdk_x11_get_default_xdisplay().

	* gdk/gdk.h gdk/gdk.c linux-fb/gdkfb.h linux-fb/gdkglobals-fb.c
	win32/gdkwin32.h x11/gdkglobals-x11.c gdk/x11/gdkmain-x11.c
	gdk/x11/gdkx.h: gdk/gdk.def: Add gdk_get/set_program_class,
	Don't export gdk_progclass, move --class command line
	option and handling to common portion of GDK.

      Miscellaneous fixes:

	* gdk/x11/gdkwindow-x11.c (gdk_window_set_icon_list): Fix
	g_return_val_if_fail that should have been g_return_if_fail.

	* gdk/gdkinternals.h gdk/gdkprivate.h: Move
	gdk_synthesize_window_state() to the semi-public gdkprivate.h.

	* gtk/gtkdnd.c (_gtk_drag_source_handle_event): Remove uneeded
	X11 dependency.

	* gdk/linux-fb/gdkmain-fb.c gdk/win32/gdkmain-win32.c gdk/TODO:
	Remove unused gdk_key_repeat_disable/restore.

	* linux-fb/gdkglobals-fb.c win32/gdkglobals-win32.c
	x11/gdkglobals-x11.c x11/gdkprivate-x11.h gdk/gdk.def:
	Remove unused gdk_null_window_warnings variable.

	* gdk/Makefile.am (DIST_SUBDIRS) nanox/*: cvs remove nanox;
	it can be retrieved from the repository; it is too far
	from functional to be worth having people check out;
	it would be easier to start from scratch, I suspect.

	* gdk/x11/gdkpixmap-x11.c: Fix lvalue usage of GDK_PIXMAP_XID().

	* gdk/x11/gdkkeys-x11.c gdk/gdkrgb.c gdk/gdkwindow.c
	gdk/x11/gdkpango-x11.c gdk/x11/gdkselection-x11.c:
	Fix some accidentally global variables and unused global variables.

	* gdk/x11/gdkkeys-x11.c gdk/gdkrgb.c gdk/gdkwindow.c
	gdk/x11/gdkpango-x11.c gdk/x11/gdkselection-x11.c:
	Fix some accidentally global variables and unused global variables.

      Add some space for future expansion to multihead.

	* gdk/gdkdrawable.h: Add four reserved function pointers
	for future expansion of GdkDrawableClass.

	* gtk/gtkwindow.h gtk/gtkinvisible.h: Add reserved pointer
	where we can put a GdkScreen * later.
