  • fix String16 request field handling when using Python 3
  • fix RECORD extension and example when using Python 3
  • fix handling of properties: use byte strings for all X11 8-bits strings, as not all of them are text properties (the window getters/setters for wm_name, wm_icon_name, wm_class, and wm_client_machine still return/expect Unicode strings)

API Changes

Core:

  • new window getter/setter for text properties: get_full_text_property and change_text_property; with automatic conversion to/from Unicode when the property type encoding is supported (STRING and UTF8_STRING)

Composite extension:

  • support for GetOverlayWindow request

Version 0.16

Licensing

The project is now licensed under the GNU Lesser General Public License v2.1 or later (see the LICENSE file for details).

Compatibility

Support for Python versions older than 2.7 has been dropped. Support for Python 3 (3.3, 3.4 and 3.5) has been added. Note that Python-Xlib now depends on the six package (>=1.10) for combined Python 2 / 3 support.

API Changes

With the change of license, and no way to contact the original author of the SHAPE extension, the code had to be rewritten from scratch. This resulted in a few minor API changes (see examples/shapewin.py).

Partial support for the SECURITY. XInput, and XFIXES extensions has been added.

Bug Fixes

  • fix RECORD extension
  • fixed OS X socket path
  • fix handling of generic events
  • fix handling of KeymapNotify events
  • several fixes for the RandR extension

Version 0.15rc1 - 14 Nov 2009

Improved support for newer versions of Mac OS X, a couple of new extensions, and several bugfixes.

Composite extension

Support for the composite extension, used to implement a composition manager (added for plcm work in plwm).

By itself this extension is not very useful, it is intended to be used together with the DAMAGE and XFIXES extensions. Typically you would also need RENDER or glX or some similar method of creating fancy graphics.

XF86 special function keysyms

Keysym definitions for special function keys found on modern keyboards, e.g. raise and lower volume, start specific applications, etc. Have a look in Xlib/keysymdef/xf86.py to see what there are and experiment with xev to see what your keyboard generates. These definitions aren't brought in by default, so you must do this after importing Xlib.XK:

Xlib.XK.load_keysym_group('xf86')

RANDR extension

The RANDR extension complements XINERAMA as a way of getting data about the physical screens making up a virtual screen in X. An example of usage can be found in examples/xrandr.py.

Version 0.14 - 1 Oct 2007 (trialed as 0.14rc1 on 10 Jun 2007)

A couple of new extensions, a Python 2.5 fix and a couple of aliases (Display.get_atom() now uses the internal cache and added Window.raise_window()). Tabs converted to spaces (SF id: 1559082).

RECORD extension (SF id: 1538663)

Alex Badea contributed a RECORD extension module, allowing Python Xlib programs to capture mouse and keyboard events (or all other core or extension events) easily. A demo is in the examples directory. See http://refspecs.freestandards.org/X11/recordlib.pdf for more information.

XINERAMA extension

Mike Meyer contributed a Xinerama extension module, allowing Python Xlib programs to interrogate the X server about positions and sizes of multiple screens. Specifications are a bit tricky to find - http://sourceforge.net/projects/xinerama/ has some older specs and the source code of the xorg project (libs & server code) has "definitive" information.

Python 2.5 fix (SF id: 1623900)

Bugfix to correct handling of XAuthority file parsing under Python 2.5 causing failed authentication.

Version 0.13 - 6 Aug 2006 (trialed as 0.13pre1 on 22 Jul 2006)

A small release to incorporate a number of minor corrections and bug fixes, including small changes to keysym handling, .Xauthority parsing, several fixes to sending/receiving/flushing data, addition of WithdrawnState to WMHints. petli completed documentation for Display objects.

Version 0.12 - 29 Mar 2002

SHAPE extension

Jeffrey Boser contributed a SHAPE extension module, allowing Python Xlib programs to use shaped windows. Take a look at examples/shapewin.py for ideas on how to use it. For more information on shaped windows, see http://ftp.x.org/pub/R6.6/xc/doc/hardcopy/Xext/shape.PS.gz

Python 2.2 fix

In Python 2.2 FCNTL.FD_CLOEXEC has disappeared and FCNTL on the whole is deprecated, so that had to be dealt with to make the Xlib work with that version.

Version 0.11 - 23 Feb 2002

Regression tests for the protocol definition

Regressions tests have been created for all requests, replies and events. The tests use PyUnit, and the old resource database test has been updated to use it too.

A lot of protocol bugfixes

The bugs discovered by the regression tests have been fixed. Additionally, a subtle bug in the core engine which could cause a "can't happen"-error has also been found and fixed.

Version 0.10 - 16 Dec 2001

Event bugfix

The xlib failed to parse the type code of events sent from other clients using SendEvent. This has been fixed, adding the field `send_event' to all event objects.

Event documentation

The section "Event Types" in the manual has been written, detailing all event types in the core protocol. The manual is now ten pages thicker.

Basic support for GetImage/PutImage

The Drawable methods put_image() and get_image() have been implemented, but handling image data is still up to the user. There is however, thanks to Ilpo Nyyssönen, a trivial method put_pil_image() that will work on some combinations of image and drawable depth. It's not perfect, but it's a start.

Version 0.9 - 4 Dec 2001

Documentation improved

The documentation has been augmented with a chapter about event handling, and a chapter listing all X objects and their methods provided by the library. They are not described in any detail, though.

Keysym handling improved

The module Xlib.XK, which listed all keysyms, have been split up into several sub-modules providing different sets of keysyms. By importing Xlib.XK only the miscellany and latin1 sets are loaded, thus removing some unnecessary clutter.

Xlib.display.Display has two new methods (lookup_string() and rebind_string()) for translating keysyms into characters.

Small changes to library interface

The order of the Xlib.display.Display method send_event() parameters event_mask and propagate has changed.

Some of the class names in Xlib.protocol.event have changed, to have the same name as the corresponding event type constant.

A few bugfixes

If a display has more than one screen, the default screen was always set to the highest numbered one, irrespective of what the user specified in $DISPLAY.

Some response attributes in Xlib.protocol.request accidentally included a comma.

Version 0.8 - 12 Jan 2001

Uses distutils

Python Xlib now uses distutils to make installation and distribution building easier.

Tested with Python 2.0

A few incompatibilities with Python 2.0 has been fixed.

Version 0.7 - 8 Jan 2001

Fixed the 64-bit platform fix.

As it turns out, the attempted fix for 64-bit platforms in v0.6 didn't really work. Close study of structmodules.c gave the answer why, and now it really should work. Yeah.

Optimizations of core protocol engine

Python Xlib is now at least 25% faster after the core of the protocol engine has been rewritten. This is some quite cute code: tailor-made methods are generated for all structures, resulting in a 650% speed-up in generating binary data, and a 75% speed-up in parsing binary data.

Interested Python hackers are recommended to take a look at the Struct class in Xlib/protocol/rq.py.

Version 0.6 - 29 Dec 2000

Fix to make python-xlib work on 64-bytes architectures.

The struct and array modules uses sizeof(long) to determine the number of bytes used when representing the type code 'l'. On Intel and VAX, this is 32 bits as expected. On Alpha, it's 64 bits. python-xlib now probes how large each type code is to avoid this problem.

Version 0.5 - 28 Dec 2000

  • Functions implemented to get and set all ICCCM WM properties on Window objects.

  • Keymap cache implemented, with external Xlib.display.Display methods keycode_to_keysym, keysym_to_keycode, keysym_to_keycodes and refresh_keyboard_mapping.

  • Two utils for debugging X traffic implemented. utils/tcpbug.py forwards a TCP connection and outputs the communication between the client and the server. This output can then be fed into utils/parsexbug.py, which will output all requests, responses, errors and events in a readable format.

Version 0.4 - 4 Oct 2000

  • Thread support completed, but not really stress-tested yet.

  • A framework for handling different platforms has been implemented, together with generic Unix code and some simple VMS code.

  • Some documentation has been written.

  • The usual bunch of bugfixes.
