to the application + + * Added helpful __repr__ for many widget classes + + * Updated all example programs to use MainLoop class + + * Updated tutorial with MainLoop usage and improved examples + + * Renamed WidgetWrap.w to _w, indicating its intended use as a way + to implement a widget with other widgets, not necessarily as + a container for other widgets + + * Replaced all tabs with 4 spaces, code is now more aerodynamic + (and PEP 8 compliant) + + * Added saving of stdin and stdout in raw_display module allowing + the originals to be redirected + + * Updated BigText widget's HalfBlock5x4Font + + * Fixed graph example CPU usage when animation is stopped + + * Fixed a memory leak related to objects listening for signals + + * Fixed a Popen3 deprecation warning + + +Urwid 0.9.8.4 +============= + +2009-03-13 + + * Fixed incompatibilities with Python 2.6 (by Friedrich Weber) + + * Fixed a SimpleListWalker with emptied list bug (found by Walter + Mundt) + + * Fixed a curses_display stop()/start() bug (found by Christian + Scharkus) + + * Fixed an is_wide_character() segfault on bad input data bug + (by Andrew Psaltis) + + * Fixed a CanvasCache with render() used in both a widget and its + superclass bug (found by Andrew Psaltis) + + * Fixed a ListBox.ends_visible() on empty list bug (found by Marc + Hartstein) + + * Fixed a tutorial example bug (found by Kurtis D. Rader) + + * Fixed an Overlay.keypress() bug (found by Andreas Klöckner) + + * Fixed setuptools configuration (by Andreas Klöckner) + + +Urwid 0.9.8.3 +============= + +2008-07-14 + + * Fixed a canvas cache memory leak affecting 0.9.8, 0.9.8.1 and + 0.9.8.2 (found by John Goodfellow) + + * Fixed a canvas fill_attr() bug (found by Joern Koerner) + + +Urwid 0.9.8.2 +============= + +2008-05-19 + + * Fixed incompatibilities with Python 2.3 + + * Fixed Pile cursor pref_col bug, WidgetWrap rows caching bug, Button + mouse_event with no callback bug, Filler body bug triggered by the + tutorial and a LineBox lline parameter typo. + + +Urwid 0.9.8.1 +============= + +2007-06-21 + + * Fixed a Filler render() bug, a raw_display start()/stop() bug and a + number of problems triggered by very small terminal window sizes. + + +Urwid 0.9.8 +=========== + +2007-03-23 + + * Rendering is now significantly faster. + + * New Widget base class for all widgets. It includes automatic caching + of rows() and render() methods. It also adds a new __super attribute + for accessing methods in superclasses. + + Widgets must now call self._invalidate() to notify the cache when + their content has changed. + + To disable caching in a widget set the class variable no_cache to a + list that includes the string "render". + + * Canvas classes have been reorganized: Canvas has been renamed to + TextCanvas and Canvas is now the base class for all canvases. New + canvas classes include BlankCanvas, SolidCanvas and CompositeCanvas. + + * External event loops may now be used with the raw_display module. The + new methods get_input_descriptors() and get_input_nonblocking() + should be used instead of get_input() to allow input processing + without blocking. + + * The Columns, Pile and ListBox widgets now choose their first + selectable child widget as the focus widget by defaut. + + * New ListWalker base class for list walker classes. + + * New Signals class that will be used to improve the existing event + callbacks. Currently it is used for ListWalker objects to notify + their ListBox when their content has changed. + + * SimpleListWalker now behaves as a list and supports all list + operations. This class now detects when changes are made to the list + and notifies the ListBox object. New code should use this class to + wrap lists of widgets before passing them to the ListBox + constructor. + + * New PollingListWalker class is now the default list walker that is + used when passing a simple list to the ListBox constructor. This + class is intended for backwards compatibility only. When this class + is used the ListBox object is unable to cache its render() method. + + * The curses_display module can now draw in the lower-right corner of + the screen. + + * All display modules now have start() and stop() methods that may be + used instead of calling run_wrapper(). + + * The raw_display module now uses an alternate buffer so that the + original screen can be restored on exit. The old behaviour is + available by seting the alternate_buffer parameter of start() or + run_wrapper() to False. + + * Many internal string processing functions have been rewritten in C to + improve their performance. + + * Compatible with Python >= 2.2. Python 2.1 is no longer supported. + + +Urwid 0.9.7.2 +============= + +2007-01-03 + + * Improved performance in UTF-8 mode when ASCII text is used. + + * Fixed a UTF-8 input bug. + + * Added a clear() function to the the display modules to force the + screen to be repainted on the next draw_screen() call. + + +Urwid 0.9.7.1 +============= + +2006-10-03 + + * Fixed bugs in Padding and Overlay widgets introduced in 0.9.7. + + +Urwid 0.9.7 +=========== + +2006-10-01 + + * Added initial support for fixed widgets - widgets that have a fixed + size on screen. Fixed widgets expect a size parameter equal to (). + Fixed widgets must implement the pack(..) function to return their + size. + + * New BigText class that draws text with fonts made of grids of + character cells. BigText is a fixed widget and doesn't do any + alignment or wrapping. It is intended for banners and number readouts + that need to stand out on the screen. + + Fonts: Thin3x3Font, Thin4x3Font, Thin6x6Font (full ascii) + + UTF-8 only fonts: HalfBlock5x4Font, HalfBlock6x5Font, + HalfBlockHeavy6x5Font, HalfBlock7x7Font (full ascii) + + New function get_all_fonts() may be used to get a list of the + available fonts. + + * New example program bigtext.py demonstrates use of BigText. + + * Padding class now has a clipping mode that pads or clips fixed + widgets to make them behave as flow widgets. + + * Overlay class can now accept a fixed widget as the widget to display + "on top". + + * New Canvas functions: pad_trim() and pad_trim_left_right(). + + * Fixed a bug in Filler.get_cursor_coords() that causes a crash if the + contained widget's get_cursor_coords() function returns None. + + * Fixed a bug in Text.pack() that caused an infinite loop when the text + contained a newline. This function is not currently used by Urwid. + + * Edit.__init__() now calls set_edit_text() to initialize its text. + + * Overlay.calculate_padding_filler() and Padding.padding_values() now + include focus parameters. + + +Urwid 0.9.6 +=========== + +2006-08-22 + + * Fixed Unicode conversion and locale issues when using Urwid with + Python < 2.4. The graph.py example program should now work properly + with older versions of Python. + + * The docgen_tutorial.py script can now write out the tutorial example + programs as individual files. + + * Updated reference documentation table of contents to show which + widgets are flow and/or box widgets. + + * Columns.set_focus(..) will now accept an integer or a widget as its + parameter. + + * Added detection for rxvt's HOME and END escape sequences. + + * Added support for setuptools (improved distutils). + + +Urwid 0.9.5 +=========== + +2006-06-14 + + * Some Unicode characters are now converted to use the G1 alternate + character set with DEC special and line drawing characters. These + Unicode characters should now "just work" in almost all terminals and + encodings. + + When Urwid is run with the UTF-8 encoding the characters are left as + UTF-8 and not converted. + + The characters converted are: + + \u00A3 (£), \u00B0 (°), \u00B1 (±), \u00B7 (·), \u03C0 (π), + \u2260 (≠), \u2264 (≤), \u2265 (≥), \u23ba (⎺), \u23bb (⎻), + \u23bc (⎼), \u23bd (⎽), \u2500 (─), \u2502 (│), \u250c (┌), + \u2510 (┐), \u2514 (└), \u2518 (┘), \u251c (├), \u2524 (┤), + \u252c (┬), \u2534 (┴), \u253c (┼), \u2592 (▒), \u25c6 (◆) + + * New SolidFill class for filling an area with a single character. + + * New LineBox class for wrapping widgets in a box made of line- drawing + characters. May be used as a box widget or a flow widget. + + * New example program graph.py demonstrates use of BarGraph, LineBox, + ProgressBar and SolidFill. + + * Pile class may now be used as a box widget and contain a mix of box + and flow widgets. + + * Columns class may now contain a mix of box and flow widgets. The box + widgets will take their height from the maximum height of the flow + widgets. + + * Improved the smoothness of resizing with raw_display module. The + module will now try to stop updating the screen when a resize event + occurs during the update. + + * The Edit and IntEdit classes now use their set_edit_text() and + set_edit_pos() functions when handling keypresses, so those functions + may be overridden to catch text modification. + + * The set_state() functions in the CheckBox and RadioButton classes now + have a do_callback parameter that determines if the callback function + registered will be called. + + * Fixed a newly introduced incompatibility with python < 2.3. + + * Fixed a missing symbol in curses_display when python is linked + against libcurses. + + * Fixed mouse handling bugs in the Frame and Overlay classes. + + * Fixed a Padding bug when the left or right has no padding. + + +Urwid 0.9.4 +=========== + +2006-05-30 + + * Enabled mouse handling across the Urwid library. + + Added a new mouse_event() method to the Widget interface definition + and to the following widgets: Edit, CheckBox, RadioButton, Button, + GridFlow, Padding, Filler, Overlay, Frame, Pile, Columns, BoxAdapter + and ListBox. + + Updated example programs browse.py, calc.py, dialog.py, edit.py and + tour.py to support mouse input. + + * Released the files used to generate the reference and tutorial + documentation: docgen_reference.py, docgen_tutorial.py and + tmpl_tutorial.html. The "docgen" scripts write the documentation to + stdout. docgen_tutorial.py requires the Templayer HTML templating + library to run: http://excess.org/templayer/ + + * Improved Widget and List Walker interface documentation. + + * Fixed a bug in the handling of invalid UTF-8 data. All invalid + characters are now replaced with '?' characters when displayed. + + +Urwid 0.9.3 +=========== + +2006-05-14 + + * Improved mouse reporting. + + The raw_display module now detects gpm mouse events by reading + /usr/bin/mev output. The curses_display module already supports gpm + directly. + + Mouse drag events are now reported by raw_display in terminals that + provide button event tracking and on the console with gpm. Note that + gpm may report coordinates off the screen if the user drags the mouse + off the edge. + + Button release events now report which button was released if that + information is available, currently only on the console with gpm. + + * Added display of raw keycodes to the input_test.py example program. + + * Fixed a text layout bug affecting clipped text with blank lines, and + another related to wrapped text starting with a space character. + + * Fixed a Frame.keypress() bug that caused it to call keypress on + unselectable widgets. + + +Urwid 0.9.2 +=========== + +2006-03-18 + + * Preliminary mouse support was added to the raw_display and + curses_display modules. A new Screen.set_mouse_tracking() method was + added to enable mouse tracking. Mouse events are returned alongside + keystrokes from the Screen.get_input() method. + + The widget interface does not yet include mouse handling. This will + be addressed in the next release. + + * A new convenience function is_mouse_event() was added to help in + separating mouse events from keystrokes. + + * Added a new example program input_test.py. This program displays the + keyboard and mouse input it receives. It may be run as a CGI script + or from the command line. On the command line it defaults to using + the curses_display module, use input_test.py raw to use the + raw_display module instead. + + * Fixed an Edit.render() bug that caused it to render the cursor in a + different location than that reported by Edit.get_cursor_coords() in + some circumstances. + + * Fixed a bug preventing use of UTF-8 characters with Divider widgets. + + +Urwid 0.9.1 +=========== + +2006-03-06 + + * BarGraph and ProgressBar can now display data more accurately by + using the UTF-8 vertical and horizontal eighth characters. This + behavior will be enabled when the UTF-8 encoding is detected and + "smoothed" attributes are passed to the BarGraph or ProgressBar + constructors. + + * New get_encoding_mode() function to determine how Urwid will treat + raw string data. + + * New raw_display.signal_init() and raw_display.signal_restore() + methods that may be overridden by threaded applications that need to + call signal.signal() from their main thread. + + * Fixed a bug that prevented the use of UTF-8 strings in text markup. + + * Removed some forgotten asserts that broke 8-bit and CJK input. + + +Urwid 0.9.0 +=========== + +2006-02-18 + + * New support for UTF-8 encoding including input, display and editing + of narrow and wide (CJK) characters. + + Preliminary combining (zero-width) character support is included, but + full support will require terminal behavior detection. + + Right-to-Left input and display are not implemented. + + * New raw_display module that handles console display without relying + on external libraries. This module was written as a work around for + the lack of UTF-8 support in the standard version of ncurses. + + Eliminates "dead corner" in the bottom right of the screen. + + Avoids use of bold text in xterm and gnome-terminal for improved + text legibility. + + * Fixed Overlay bug related to UTF-8 handling. + + * Fixed Edit.move_cursor_to_coords(..) bug related to wide characters + in UTF-8 encoding. + + +Urwid 0.9.0-pre3 +================ + +2006-02-13 + + * Fixed Canvas attribute padding bug related to -pre1 changes. + + +Urwid 0.9.0-pre2 +================ + +2006-02-10 + + * Replaced the custom align and wrap modes in example program calc.py + with a new layout class. + + * Fixed Overlay class call to Canvas.overlay() broken by -pre1 changes. + + * Fixed Padding bug related to Canvas -pre1 changes. + + +Urwid 0.9.0-pre1 +================ + +2006-02-08 + + * New support for UTF-8 encoding. Unicode strings may be used and will + be converted to the current encoding when output. Regular strings in + the current encoding may still be used. + + PLEASE NOTE: There are issues related to displaying UTF-8 characters + with the curses_display module that have not yet been resolved. + + * New set_encoding() function replaces util.set_double_byte_encoding(). + + * New supports_unicode() function to query if unicode strings with + characters outside the ascii range may be used with the current + encoding. + + * New TextLayout and StandardTextLayout classes to perform text + wrapping and alignment. Text widgets now have a layout parameter to + allow use of custom TextLayout objects. + + * New layout structure replaces line translation structure. Layout + structure now allows arbitrary reordering/positioning of text + segments, inclusion of UTF-8 characters and insertion of text not + found in the original text string. + + * Removed util.register_align_mode() and util.register_wrap_mode(). + Their functionality has been replaced by the new layout classes. + + +Urwid 0.8.10 +============ + +2005-11-27 + + * Expanded tutorial to cover advanced ListBox usage, custom widget + classes and the Pile, BoxAdapter, Columns, GridFlow and Overlay + classes. + + * Added escape sequence for "shift tab" to curses_display. + + * Added ListBox.set_focus_valign() to allow positioning of the focus + widget within the ListBox. + + * Added WidgetWrap class for extending existing widgets without + inheriting their complete namespace. + + * Fixed web_display/mozilla breakage from 0.8.9. Fixed crash on invalid + locale setting. Fixed ListBox slide-back bug. Fixed improper space + trimming in calculate_alignment(). Fixed browse.py example program + rows bug. Fixed sum definition, use of long ints for python2.1. Fixed + warnings with python2.1. Fixed Padding.get_pref_col() bug. Fixed + Overlay splitting CJK characters bug. + + +Urwid 0.8.9 +=========== + +2005-10-21 + + * New Overlay class for drawing widgets that obscure parts of other + widgets. May be used for drop down menus, combo boxes, overlapping + "windows", caption text etc. + + * New BarGraph, GraphVScale and ProgressBar classes for graphical + display of data in Urwid applications. + + * New method for configuring keyboard input timeouts and delays: + curses_display.Screen.set_input_timeouts(). + + * Fixed a ListBox.set_focus() bug. + + +Urwid 0.8.8 +=========== + +2005-06-13 + + * New web_display module that emulates a console display within a web + browser window.
