* gdk/gdk.def: Reflect recent renamings and removals of functions.
Merge from stable:
Start implementing all fill styles (i.e. tiled, stippled, and
opaque stippled in addition to the plain solid style) in the Win32
backend in an elegant and generic way. For now only did the
draw_rectangle() and draw_glyphs() methods. The rest will
follow. Previously some of the drawing methods implemented opaque
stippling, but not tiles or non-opaque stippling.
Seems to work fine, now the check marks show up in check buttons,
the stippled background and stippled text in gtk-demo's Text
Widget look as they should, and GtkText's line wrap arrow shows
correctly instead of an ugly rectangle. [This refers to the stable
branch, haven't actually checked HEAD.]
The implementation does do a lot of pixmap handling and blitting
back and forth, especially on Win9x. But performance is hopefully
not an issue. I don't think many applications do a lot of tiled or
stippled drawing.
* gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that
calls a GDI function and prints a warning if it failed. Also
API_CALL for non-GDI calls. Cleans all the the if (!BlaBla())
WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written
GDI_CALL (BlaBla, ()). Declare new functions.
* gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places.
(generic_draw): New function that handles all the blitting
necessary to implement tiles and stipples. A function that
actually draws stuff is passed as a parameter to
generic_draw(). If the fill style is solid, it is called
directly, to draw on the destination drawable. Otherwise it is
called to draw on a temporary mask bitmap, which then is used in
blitting operations. The tiles and/or stipples are rendered into
another temporary pixmap. If MaskBlt() is available (on NT/2k/XP),
it is used, otherwise a sequence of BitBlt() is used to do the
final composition onto the destination drawable.
(draw_tiles_lowlevel, draw_tiles): Some renaming and code
reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable().
(rop2_to_rop3): New function, does binary->ternary rop mapping.
(blit_from_pixmap, blit_inside_window, blit_from_window): Use
rop2_to_rop3(). Previously used SRCCOPY always...
(draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs,
gdk_win32_draw_glyphs): Split functionality into two functions,
with generic_draw() doing its magic inbetween.
* gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it
was ifdeffed out and wouldn't have done anything even if
enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't
have any effect any more anyway after all the changes GTK+ has
gone through in the last years. Remove some #if 0 code.
* gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field
to NULL in case a GC is copied while it has a Windows DC active.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc.
* gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc
option. If there is a PRETEND_WIN9X envvar, set windows_version as
if on Win9x.
* gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new,
gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't
used or exported. Make a bit more like the X11 version. Hopefully
I didn't break the fragile palettized display ("pseudocolor")
code.
* gdk/win32/gdkgc-win32.c: Various debugging output improvements.
(predraw_set_foreground): Check whether
tile/stipple origins are valid when calling SetBrushOrgEx().
(gdk_win32_hdc_get): Ifdef out code that tries to handle the
stipple by converting it into a region, and combining the clip
region with that. A stipple shouldn't work like that, it should
replicate in x and y directions. Stipples are now handled by
generic_draw() in gdkdrawable-win32.c.
* gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string,
gdk_win32_rop2_to_string): New debugging functions.
(gdk_win32_print_dc): Print also DC's rop2 and text color.

General Information
===================
This is GTK+ version 2.1.2. 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.
The official ftp site is:

Installation
============
See the file 'INSTALL'
GTK+-2.0.0 Specific Notes
=========================
* The default configuration of GTK+ has been stream-lined to reduce
confusion on the part of new users or users coming from other
environments. Users used to older versions of GTK+ may want to make
some adjustments to the default configuration.
- Emacs keybindings such as Control-A and Control-E to move to the
ends of lines are not enabled by default in the editing widgets. To
turn on Emacs keybindings, add the line:
gtk-key-theme-name = "Emacs"
To your ~/.gtkrc-2.0
- Editing of menu accelerators by pressing an accelerator over the
menu item is disabled by default. To enable, it, add:
gtk-can-change-accels = 1
to your ~/.gtkrc-2.0
- To improve useability for keyboard operation, GTK+ now selects the
contents of an entry when tabbing into it or when it is focused on
initial window map. To disable this behavior, add:
gtk-entry-select-on-focus = 0
to your ~/.gtkrc-2.0
* The GTK+ libraries use an '_' prefix to indicate private symbols that
must not be used by applications. The intention was not to export
symbols beginning with prefixes such as _gtk, _gdk, and _pango from
the libraries at all, but due to a bug in libtool, they are actually
exported at the moment on some platforms (including Linux).
Applications that use these private symbols _will_ break when
this bug is fixed.
* The Xft library that GTK+ uses to display anti-aliased fonts will
undergo a major version revision in the next few months. To deal with
this, by default, GTK+ and Pango are built so that applications will
not have explicit dependencies on version 1 on Xft. To make sure that
your application will be binary compatible with future versions of
GTK+:
- Do not configure Pango or GTK+ with the --enable-static or
--enable-explicit otions, since they will cause dependencies on
Xft version 1.
- Do not use Xft directly in your applicatons.
* There is a bug in the Xft library in XFree86-4.1 and possibly previous
versions that causes random crashes when using the Pango Xft
backend. If you want to use Xft fonts, you should upgrade to
XFree86-4.2.
* Xft support is not on by default. To turn it on set the environment
variable GDK_USE_XFT to '1'
GDK_USE_XFT=1
export GDK_USE_XFT
* The gdk_pixbuf_xlib library included in the contrib/ directory of GTK+
is provided on a as-is basis and has not been tested at all. No
guarantees about the degree of workingness or about future
compatibility are provided.
* There are known problems with some of the image loaders in the
gdk-pixbuf library included in GTK+ where corrupted images can cause
crashes and conceivably worse problems. Until these problems are fixed
(we hope to have this done for 2.0.1), gdk-pixbuf should not be used
to load untrusted data.
* 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_BROKEN_FILENAMES environment variable:
G_BROKEN_FILENAMES=1
export G_BROKEN_FILENAMES
Best integration of GTK+-2.0 with the environment is achieved by
using a UTF-8 locale.
How to report bugs
==================
Bugs should be reported to the GNOME bug tracking system.
(http://bugzilla.gnome.org, product gtk+.) You will need to create an
account for yourself.
In the bug report please include:
* Information about your system. For instance:
- What operating system and version
- What version of X
- For Linux, what version of the C library
And anything else you think is relevant.
* How to reproduce the bug.
If you can reproduce it with the testgtk program that is built in the
gtk/ subdirectory, that will be most convenient. Otherwise, please
include a short test program that exhibits the behavior. As a last
resort, you can also provide a pointer to a larger piece of software
that can be downloaded.
* If the bug was a crash, the exact text that was printed out when the
crash occured.
* Further information such as stack traces may be useful, but is not
necessary. If you do send a stack trace, and the error is an X error,
it will be more useful if the stacktrace is produced running the test
program with the --sync command line option.
Patches
=======
Patches should also be submitted to bugzilla.gnome.org. If the patch
fixes an existing bug, add the patch as an attachment to that bug
report.
Otherwise, enter a new bug report that describes the patch, and attach
the patch to that bug report.
Bug reports containing patches should include the PATCH keyword in their
keyword fields. If the patch adds to or changes the GTK programming
interface, the API keyword should also be included.
Patches should be in unified diff form. (The -u option to GNU diff.)
