General Information
|
|
===================
|
|
|
|
This is GTK+ version 2.8.1. 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.

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.

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 one of the tests or demos built with GTK+,
|
|
such as demos/gtk-demo/gtk-demo, that would 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.)
