 Prerequisites
 =============
 
-GTK+ requires the GLIB library, available at the same location as
-you got this package.
+GTK+ requires the following packages:
+
+ - The GLib, Pango, and Atk libraries, available at the same location as GTK+
+   (Either Pango-1.0 or Pango-1.2 can be used with GTK+-2.2; 
+   Pango-1.2 is recommended.)
+
+ - The TIFF, PNG, and JPEG image loading libraries. You most
+   likely have these installed on your system already. If not
+   these libraries are available from:
+
+    http://www.libtiff.org/
+    http://www.libpng.org/
+    http://www.ijg.org/
 
 Simple install procedure
 ========================
 
-  % gzip -cd gtk+-1.2.5.tar.gz | tar xvf - # unpack the sources
-  % cd gtk+-1.2.5			   # change to the toplevel directory
+  % gzip -cd gtk+-2.6.6.tar.gz | tar xvf - # unpack the sources
+  % cd gtk+-2.6.6			   # change to the toplevel directory
   % ./configure				   # run the `configure' script
   % make				   # build GTK
   [ Become root if necessary ]
   % make install			   # install GTK
 
-The Nitty-Gritty
-================
+The Details
+===========
 
-The 'configure' script can be given a number of options to enable
-and disable various features. For a complete list, type:
+Complete information about installing GTK+ and related libraries can be found 
+in the file:
 
-  ./configure --help
+ docs/reference/gtk/html/gtk-building.html
 
-A few of the more important ones:
-
-*  --prefix=PREFIX         install architecture-independent files in PREFIX
-                           [ Defaults to /usr/local ]
-
-*  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                           [ Defaults to the value given to --prefix ]
-
-*  --with-xinput=[no/gxi/xfree] support XInput [default=no]
-
-The --with-xinput flag specifies whether to compile with support
-for the XInput extension (mainly used for graphics tablets), and
-which form of support to use:
-
-  no    : no support 
-  gxi   : Use generic XInput support
-  xfree : Use special features in the Wacom drivers in XFree86 3.3.1
-          and later.
-
-For more information, follow the link from http://www.gtk.org
-
-*  --disable-nls           do not use Native Language Support
-
-If this flag is not specified, GTK+ will try to find
-and use the gettext() set of functions to provide translations
-of the strings in the standard dialogs into the
-user's native language.
-
-*  --enable-xim            support XIM [default=yes]
-
-Specifying --disable-xim will disable support for entering
-internationalized text using X Input Methods. This will give some
-slight savings in speed and memory use and might be necessary
-with older versions of X.
-
-*  --with-locale=LOCALE    locale name you want to use
-
-The --with-locale options is used to determine if your operating
-system has support for the locale you will be using. If not, X's
-built in locale support will be used.
-
-Because of bugs in autoconf, it is necessary to specify this
-option even if your LANG environment variable is correctly set.
-
-This option does not determine which locale GTK will use at
-runtime. That will be determined from the usual environment
-variables.  If you will be using multiple locales with GTK,
-specify the one for which your operating system has the worst
-support for the --with-locale option.
-
-
-Options can be given to the compiler and linker by setting
-environment variables before running configure. A few of the more
-important ones:
-
- CC       : The C compiler to use
- CPPFLAGS : Flags for the C preprocesser such as -I and -D
- CFLAGS   : C compiler flags
-
-The most important use of this is to set the
-optimization/debugging flags. For instance, to compile with no
-debugging information at all, run configure as:
-
- CFLAGS=-O2 ./configure           # Bourne compatible shells (sh/bash/zsh)
-
-or,
-
- setenv CFLAGS -O2 ; ./configure  # csh and variants
-
-Native-Language Support and gettext()
-=====================================
-
-To provide native-language support (NLS) GTK+ uses the
-gettext() set of functions. These functions are found
-in the C library on many systems, such as the Solaris
-C library and the GNU C Library, version 2.
-
-If your C library does not provide the necessary functionality,
-you may wish to install the GNU gettext package. You'll
-need version 0.10.35 or better. Version 0.10.35 is
-available from ftp://alpha.gnu.org/pub/gnu
-
-Generally, GTK+ will properly detect what is installed
-on your system and enable or disable NLS as appropriate.
-However, in rare cases, it may be necessary to disable
-NLS manually to get GTK+ to compile. You can do this
-by specifying the --disable-nls flag when configuring
-GTK+.
-
-Using an uninstalled copy of GLIB [ Unsupported ]
-=================================================
-
-You can compile GTK+ against a copy of GLIB that you have not
-yet installed. To do this, give the --with-glib=DIR options
-to ./configure. For instance:
-
- ./configure --with-glib=../glib-1.2.5
-
-This, however, will not work if you built GLIB with different
-source and build directories.
-
-It is recommended that you install GLIB before compiling
-GTK+. The --with-glib option is not regularly tested
-and may not function correctly. In addition, 
-inter-library dependencies won't be generated when
-using --with-glib=.
-
-Installation directories
-========================
-
-The location of the installed files is determined by the --prefix
-and --exec-prefix options given to configure. There are also more
-detailed flags to control individual directories. However, the
-use of these flags is not tested.
-
-One particular detail to note, is that the architecture-dependent
-include file glibconfig.h is installed in:
-
-  $exec_pref/lib/glib/include/
-
-if you have a version in $prefix/include, this is out of date
-and should be deleted.
-
-A shell script gtk-config is created during the configure
-process, and installed in the bin/ directory
-($exec_prefix/bin). This is used to determine the location of GTK
-when building applications.  If you move GTK after installation,
-it will be necessary to edit this file.
-
-For complete details, see the file docs/gtk-config.txt
-
-
-Notes for using XIM support for Japanese input
-==============================================
-
-* There is a bug in older versions of kinput2 that will cause GTK+
-to hang when destroying a text entry. The latest versions of
-kinput is available from:
-
-  ftp://ftp.sra.co.jp/pub/x11/kinput2
-
-* The locale information file for the ja_JP EUC locale
-distributed with some recent versions of X11 specifies to use the
-C library multibyte functions. Unless your C library has support
-for Japanese locales, this is incorrect, and will cause problems
-for GTK's internationalization.
-
-(In particular, this occurs with GNU libc 2.0 and 2.1, in which
-the multibyte functions always translate to and from UTF-8; but
-the problem may occur for other C libraries, and other operating
-systems as well.)
-
-To fix this, change the line:
-
-use_stdc_env		True
-
-to 
-
-use_stdc_env		False
-
-in the file /usr/X11R6/lib/X11/locale/ja_JP/XLC_LOCALE.

 General Information
 ===================
 
-This is GTK+ version 1.2.0.   GTK+, which stands for the Gimp ToolKit, 
-is a library for creating graphical user interfaces for the X Window 
-System. It is designed to be small, efficient, and flexible. GTK+ is 
-written in C with a very object-oriented approach.
+This is GTK+ version 2.6.6. GTK+ is a multi-platform toolkit for
+creating graphical user interfaces. Offering a complete set of widgets,
+GTK+ is suitable for projects ranging from small one-off projects to
+complete application suites.
+
+GTK+ is free software and part of the GNU Project. However, the
+licensing terms for GTK+, the GNU LGPL, allow it to be used by all
+developers, including those developing proprietary software, without any
+license fees or royalties.

 Installation
 ============
 
 See the file 'INSTALL'
 
+Release notes
+=============
+
+* GTK+ 2.6 supports clipboard persistency. To make use of this feature,
+  a clipboard manager following the specification at
+  http://www.freedesktop.org/wiki/Standards/clipboard-manager-spec
+  must be running. A sample implementation of such a clipboard manager
+  is available at 
+  http://people.imendio.com/andersca/archives/clipboard-manager-0.3.tar.gz
+  Applications can use the function gdk_display_supports_clipboard_persistence() 
+  to find out if clipboard persistence is available.
+
+* Notification on clipboard ownership changes via GdkOwnerChange events 
+  requires the XFIXES X extension. Applications can use the function
+  gdk_display_supports_selection_notification() to find out if ownerchip
+  change notification is available.
+
+* The icon theme code in GTK+ 2.6 follows the freedesktop.org icon theme 
+  specification. Setting the XDG_DATA_DIRS environtment variable may be 
+  necessary if your icons aren't installed in the default location 
+  /usr/share/icons.
+
+* The icon theme code in GTK+ 2.6 can make use of mmap()able cache files
+  to avoid a lot of disk searching overhead. GTK+ includes a utility named
+  gtk-update-icon-cache to generate these cache files. For further details,
+  see the gtk-update-icon-cache man page or the GTK+ documentation.
+
+* To reduce code size and improve efficiency, GTK+, when compiled 
+  with the GNU toolchain, has separate internal and external entry 
+  points for exported functions. The internal names, which begin with 
+  IA__, may be seen when debugging a GTK+ program.
+
+* The following functions have been deprecated in GTK+ 2.6:
+  gdk_pango_context_set_colormap
+  gtk_cell_renderer_editing_canceled
+
+* The new GtkFileChooser widget emphasizes simplicity and thus does 
+  not provide a navigation entry by default when opening files. 
+  Experienced command line users will likely want to make heavy use of
+  the location dialog brought up by the Control-L key shortcut.
+
+* The GTK+ libraries use an '_' prefix to indicate private symbols that
+  must not be used by applications. On some platforms, symbols beginning 
+  with prefixes such as _gtk, _gdk, and _pango will be exported
+  from the library, on others not. In no case can applications
+  use these private symbols. In addition to that, GTK+ 2.6 makes several
+  symbols private which were not in any installed header files and
+  were never intended to be exported.
+
+* The gdk_pixbuf_xlib library included in the contrib/ directory 
+  and the framebuffer GDK backend included in the gdk/linux-fb directory
+  of GTK+ are provided on an as-is basis and have not been tested at all. 
+  No guarantees about the degree of workingness or about future
+  compatibility are provided.
+
+* On Unix, the assumption of GLib and GTK+ by default is that filenames on 
+  the filesystem are encoded in UTF-8 rather than the encoding of the locale;
+  the GTK+ developers consider that having filenames whose interpretation
+  depends on the current locale is fundamentally a bad idea.
+
+  If you have filenames encoded in the encoding of your locale, then you 
+  may want to set the G_FILENAME_ENCODING environment variable:
+  
+   G_FILENAME_ENCODING=@locale
+   export G_FILENAME_ENCODING
+
+  (Earlier versions of GLib 2.x required a different environment variable
+  setting; G_BROKEN_FILENAMES=1 to achieve the same effect; this 
+  is still supported, but G_FILENAME_ENCODING is preferred.)
+  Best integration of GTK+ 2.6 with the environment is achieved by 
+  using a UTF-8 locale.
+
+  On Windows, filenames passed to GTK+ should always be in UTF-8, as
+  in GLib 2.6. This is different than in previous versions of GTK+
+  where the system codepage was used. As in GLib, for DLL ABI
+  stability, applications built against previous versions of GTK+ will
+  use entry points providing the old semantics.
+
+  When compiling against GTK+ 2.6, applications intended to be
+  portable to Windows must take the UTF-8 file name encoding into
+  consideration, and use the gstdio wrappers to access files whose 
+  names have been constructed from strings returned from GTK+ or GLib.

+that branch is 1.3.0. It corresponds most closely to GTK 1.2.7 on
+Unix. For new code, you shouldn't be using that.

+Building GTK+ on Win32
+======================
+
+There are two ways to build GTK+ for win32.
+
+1) Use the autoconf-generated configure script, and the resulting
+Makefiles (which use libtool and gcc to do the compilation). I use
+this myself, but it can be hard to setup correctly.
+
+Personally I run configure with:
+CC='gcc -mpentium -fnative-struct' CPPFLAGS='-I/target/include' CFLAGS=-O2 LDFLAGS='-L/target/lib' ./configure --disable-static --prefix=/target --with-gdktarget=win32 --with-wintab=/src/wtkit126 --with-ie55=/src/workshop/ie55_lib --host=i386-pc-mingw32
+
+Then, in theory, you can just say "make", like on Unix. In reality,
+there are a few hickups that require manual intervention, and it's
+best to run make separately in each subdirectory. At least for me,
+when libtool creates an .exe file, it puts the real .exe in the .libs
+directory, and leaves a wrapper .exe in the work directory. For some
+reason that wrapper doesn't work for me, it doesn't do anything. So, I
+always do a "cp .libs/*.exe ." after running a make that has produced
+some exes.
+
+Another issue is with the gdk-pixbuf.loaders file. It's probably best
+to do a "make install" in the gdk-pixbuf directory, and let that set
+up a mostly correct gdk-pixbuf.loaders in the target directory. Then
+copy that back to the source directory. It's needed in gtk/stock-icons
+where make runs gdk-pixbuf-csource.
+
+Etc, you get the idea. It can be a bit of a pain.
+
+2) Use the Microsoft compiler, cl and Make, nmake. Say nmake -f
+makefile.msc in gdk and gtk. Be prepared to manually edit various
+makefile.msc files, and the makefile snippets in build/win32.
+
+Alternative 1 also generates Microsoft import libraries (.lib), if you
+have lib.exe available. It might also work for cross-compilation from
+Unix.
+
+Note that I use method 1 myself. Hans Breuer has been taking care of
+the MSVC makefiles. At times, we disagree a bit about various issues,
+and for instance the makefile.msc files will not produce identically
+named DLLs and import libraries as the "autoconfiscated" makefiles and
+libtool do. If this bothers you, you will have to fix the makefiles.
+
+Using GTK+ on Win32
+===================
+
+To use GTK+ on Win32, you also need either one of the above mentioned
+compilers. Other compilers might work, but don't count on it. Look for
+prebuilt developer packages (DLLs, import libraries, headers) on the
+above website.
+
+Multi-threaded use of GTK+ on Win32
+===================================
+
+Multi-threaded GTK+ programs might work on Windows in special simple
+cases, but not in general. Sorry. If you have all GTK+ and GDK calls
+in the same thread, it might work. Otherwise, probably not at
+all. Possible ways to fix this are being investigated.
+
+Wintab
+======
 
 The tablet support uses the Wintab API. The Wintab development kit can
-be downloaded from http://www.pointing.com. If you don't care for
-that, undefine HAVE_WINTAB in config.h.win32 and remove references to
-the wntab32x library from the makefile before building.
+be downloaded from http://www.pointing.com. Pass the --with-wintab

+for Wintab, undefine HAVE_WINTAB in config.h.win32 and remove
+references to the wntab32x library from the makefile before building.
 
-GTk+ wants to be built with the GNU "intl" library for
-internationalisation (i18n). Get the version ported to Win32 (not a
-very big deal) from tml's web site mentioned above. We build the
-"intl" library as a DLL called gnu-intl.dll (the "gnu" prefix is used
-to reduce name clash risks). If you don't want any i18n stuff,
-undefine ENABLE_NLS, HAVE_GETTEXT and HAVE_LIBINTL in the
-config.h.win32 file, and remove references to the gnu-intl library
-from the makefiles.
+ActiveIMM
+=========
 
-Note that while the GNU gettext package is under the GPL, the "intl"
-part of it as distributed with GNU libc is under the LGPL (like GTk+
-or GLib). We want the LGPL one, even if they are the same, more or
-less.
+If you want to build a GTK+ that supports ActiveIMM (the Input Method

-
-Outstanding items:
-
- * focus handling for GtkOptionMenu (needs the previous)
-
- * implement gtk_default_draw_oval and other missing things in gtkstyle.c.
- 
- * enforce invariants on *_RESIZE* and *_REDRAW* flags.
-
- * GtkToolTips: allocate GtkTooltipsData from memchunks
-                          
- * Make all widget attributes configurable after the widget is created (timj).
- 
- * Radio buttons need to display CAN/HAS_DEFAULT correctly, if draw_inidicator
-   is TRUE. (Radio buttons do not need to CAN_DEFAULT! OWT)
-
- * More dialogs: Print, maybe others...
-
- * make the gtk_main callbacks consistent in their add/remove behaviour.
- 
- * Check return values on all calls to XIC[Get/Set]Values
-
- * The "--geometry" option should be supported
-
-  - Having gdk_init() parse the geometry option. (putting it into
-    GDK means you can use XParseGeometry() without wrapping it)
-
-  - Add a call gdk_get_geometry() that retrieves the results 
-    in a form like that returned by XParseGeometry()
-
-  - The application then can modify the results (as would gemvt)
-    then call a routine gtk_window_set_geometry() on whatever
-    it considers to be its main window.
-
-  - Then in some manner GtkWindow takes that into account when
-    setting its hints. (Probably it uses the size and position
-    as the current uposition and usize, and modulates that
-    be the equivalents of the X flags
-
-     XValue, YValue, WidthValue, HeightValue, XNegative, or YNegative
-
-    ( You'd have to extend gdk_window_set_hints to accept the
-      window gravity option to get it right. )
-
- * Allow moving the separator for paned widgets by dragging 
-   it directly instead of using the handle. 
-
- * Check into XAddConnectionWatch - is this needed for XIM?
-
- * Places where a _full variant is needed:
-
-    gtk_init_add
-    gtk_menu_popup
-    gtk_toolbar_prepend_element
-    gtk_toolbar_insert_element
- 
- * Try to rationally deal with someone else deleting one of our
-   windows??? This would mean keeping track of our window heirarchy
-   ourselves, for one thing, and will never be safe, because of
-   race conditions.
-
- * Should all the default handlers really return FALSE? This can
-   cause confusing presses to be sent to containers that actually
-   want to get events on themselves.
-
- * The menu code should skip separators during keyboard navigation,
-   whether they are sensitive or insensitive.
-
- * OwnerButtonPressGrab needs to go!
-
-Text/Edit widget:
-
-  Bugs:
-
-  - Really big font (150 pt), plus lots of editing caused segfault
-
-  Improvements:
-
-  - Unify the key binding support in some fashion between the
-    Entry and Text widget widgets, use GtkBindings for this.
-
-  - Figure out a way not to recompute the geometry on insertions/deletions
-    which are large, but not a significant fraction of the
-    entire text. (e.g., compute the changes as when the widget
-    is not frozen, but without the actual scrolling)
-
-  - Prune the line start cache. But since it is only 68 bytes
-    per line, and it is a lot faster when lines are in the cache,
-    it may be better not to, at least for now.
-
-  - Show the non-editable state by changing colors. (Use the
-    style entries for insensitive?)
-
-  - Multibyte support for the Text widget.
-
-  - Unicode support to do the multi-byte right.
-
-  - Support an .inputrc. (The readline one doesn't really work,
-    unless it is extended because it can't represent X keysyms,
-    just terminal type input)
-
-  - A vi mode
-
-  - Word wrap, instead of line folding. (Should the continuation
-    characters be shown?)
-
-  - Horizontal scrolling
-
-  - Disable pasting compound text
-
-  - When showing background pixmap (not editable) actually set
-    the background pixmap as the windows bg pixmap, to improve
-    appearance on exposes. But this would require using another
-    window to get the origins.
-
-  - In word wrap mode, break:
-
-     aaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
-
-     as:
-                            | Maximum column
-     aaaaaaaaaaa bbbbbbbbbbb|
-     bbbbbbbbbbbbbbbbbbbbbbb|
-     bbbbbbbbb              |
-
-     Instead of:
-                            | 
-     aaaaaaaaaaa            |
-     bbbbbbbbbbbbbbbbbbbbbbb|
-     bbbbbbbbbbbbbbbbbbbb   |
-
-  - Blinking cursor
-
-  - API's : gtk_text_clear, gtk_text_delete_lines (gint start, gint end),
-    gtk_text_append/prepend, gtk_text_insert_at (gint row, gint column),
-    some function to get the row/column from the x/y-coordinates of a 
-    mouse click, some function to get the word/line under the mouse pointer 
-    [ From: Stefan Jeske <jeske@braunschweig.netsurf.de> ]
-
-  - "changed" emitted when doing deletes on empty Text widget.
-
-  - Delete IC in editable->unrealize, not editable->finalize?
-
-Themes
-======
-
- - When a scale gets shown/hidden only queue a redraw on the
-   non-window portion, not the whole area.
-
- - In various places, to avoid shaping windows excessively,
-   we set parent relative backgrounds. This is an ugly
-   hack and needs a better solution. Plus, I don't think
-   these parent-relative backgrounds always persist to
-   when they are actually needed.
-
-   Such calls exist in: GtkButton, GtkHandeBox, GtkItem,
-   GtkListItem, GtkMenu, GtkMenuItem, GtkMisc, 
-   GtkNoteBook, GtkOptionMenu, GtkPaned, GtkPreview,
-   GtkSpinButton and GtkTreeItem.
-
- - For menus and for GtkWindow's, the realize() function
-   calls paint(), so that background pixmaps can be set
-   ahead of time, and prevent flashing when the window is
-   shown. This is an ugly hack and needs a better solution.
-
-=======
-
-Calendar Widget:
-
- - The widget should be nicely resizeable vertical too.
-
- - CALENDAR_MARGIN should be removed, uses INNER_BORDER and
-   style->class->[xy]thickness insted.
-
- - Flag to choose between using standard three letter abbreviated
-   weekday name or just the first character from it. It looks like
-   that is what most other calendar-widgets do.
-
- - Arrows should resize with the header-font.
-
- - The keyboard support has to be finished.
-
-DND
-===
-
- - Use a cursor instead of an ICON when over Motif windows,
-   to get rid of the current junk that Motif leaves because
-   of it's XCopyArea stupidity for doing highlighting.
-
- - Add a GTK_DRAG_VERIFY target flag and a "drag_data_verify"   
-   signal so that apps can easily check if a, say, 
-   text/uri-list URL looks OK during the drop.
-
- - Check more for memory leaks.
-
- - Drag and drop for Entry and Text widgets.
-
- - Send synthetic motion events on structure changes so 
-   drag_enter/leave get sent properly. (See the popup
-   in testdnd)

+	port of GdkRGB for rendering):
+
+	* configure.in: check for X libraries, set and substitute
+	GDK_PIXBUF_XLIB_{LIBDIR,INCLUDEDIR,LIBS} variables
+

+
+	* gdk-pixbuf/gdk-pixbuf-xlibrgb.c,

+/* Change Display
+ * 
+ * Demonstrates migrating a window between different displays and
+ * screens. A display is a mouse and keyboard with some number of
+ * associated monitors. A screen is a set of monitors grouped
+ * into a single physical work area. The neat thing about having
+ * multiple displays is that they can be on a completely separate
+ * computers, as long as there is a network connection to the
+ * computer where the application is running.
+ *
+ * Only some of the windowing systems where GTK+ runs have the
+ * concept of multiple displays and screens. (The X Window System
+ * is the main example.) Other windowing systems can only
+ * handle one keyboard and mouse, and combine all monitors into
+ * a single screen.
+ *
+ * This is a moderately complex example, and demonstrates:
+ *
+ *  - Tracking the currently open displays and screens
+ *
+ *  - Changing the screen for a window
+ *
+ *  - Letting the user choose a window by clicking on it
+ * 
+ *  - Using GtkListStore and GtkTreeView
+ *
+ *  - Using GtkDialog

+/* Menus
+ *
+ * There are several widgets involved in displaying menus. The
+ * GtkMenuBar widget is a horizontal menu bar, which normally appears
+ * at the top of an application. The GtkMenu widget is the actual menu
+ * that pops up. Both GtkMenuBar and GtkMenu are subclasses of
+ * GtkMenuShell; a GtkMenuShell contains menu items
+ * (GtkMenuItem). Each menu item contains text and/or images and can
+ * be selected by the user.
+ *
+ * There are several kinds of menu item, including plain GtkMenuItem,
+ * GtkCheckMenuItem which can be checked/unchecked, GtkRadioMenuItem
+ * which is a check menu item that's in a mutually exclusive group,
+ * GtkSeparatorMenuItem which is a separator bar, GtkTearoffMenuItem
+ * which allows a GtkMenu to be torn off, and GtkImageMenuItem which
+ * can place a GtkImage or other widget next to the menu text.
+ *
+ * A GtkMenuItem can have a submenu, which is simply a GtkMenu to pop
+ * up when the menu item is selected. Typically, all menu items in a menu bar
+ * have submenus.
+ *
+ * GtkUIManager provides a higher-level interface for creating menu bars
+ * and menus; while you can construct menus manually, most people don't
+ * do that. There's a separate demo for GtkUIManager.

+ * This is typically useful when you want a column of widgets to 
+ * have the same size, but you can't use a GtkTable widget.

+ * Note that size groups only affect the amount of space requested,
