Urwid 0.9.8


  • 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.



  • 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.



  • Fixed bugs in Padding and Overlay widgets introduced in 0.9.7.

Urwid 0.9.7


  • 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 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


  • Fixed Unicode conversion and locale issues when using Urwid with Python < 2.4. The example program should now work properly with older versions of Python.
  • The 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


  • 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 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


  • 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,,, and to support mouse input.

  • Released the files used to generate the reference and tutorial documentation:, and tmpl_tutorial.html. The “docgen” scripts write the documentation to stdout. requires the Templayer HTML templating library to run:

  • 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


  • 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 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


  • 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 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 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


  • 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


  • 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


  • Fixed Canvas attribute padding bug related to -pre1 changes.

Urwid 0.9.0-pre2


  • Replaced the custom align and wrap modes in example program 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


  • 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


  • 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.

  • Added support for ncurses’ use_default_colors() function to curses_display module (Python >= 2.4).

    register_palette() and register_palette_entry() now accept “default” as foreground and/or background. If the terminal’s default attributes cannot be detected black on light gray will be used to accomodate terminals with always-black cursors.

    “default” is now the default for text with no attributes. This means that areas with no attributes will change from light grey on black (curses default) to black on light gray or the terminal’s default.

  • Modified examples to not use black as background of Edit widgets.

  • Fixed curses_display curs_set() call so that cursor is hidden when widget in focus has no cursor position.

  • Added support for CJK double-byte encodings.

    Word wrapping mode “space” will wrap on edges of double width characters. Wrapping and clipping will not split double width characters.

    curses_display.Screen.get_input() may now return double width characters. Text and Edit classes will work with a mix of regular and double width characters.

  • Use new method Edit.set_edit_text() instead of Edit.update_text().

  • Minor improvements to example program.

Urwid 0.8.2
