Configuration object
====================

The :class:`Config` object is an instance of a modified Python ConfigParser.
See the `ConfigParser documentation
<http://docs.python.org/library/configparser.html>`_ for more information.

Kivy has a configuration file which determines the default settings. In
order to change these settings, you can alter this file manually or use
the Config object. Please see the :ref:`Configure Kivy` section for more
information.

Applying configurations
-----------------------

Configuration options control the initialization of the :class:`~kivy.app.App`.
In order to avoid situations where the config settings do not work or are not
applied before window creation (like setting an initial window size),
:meth:`Config.set <kivy.config.ConfigParser.set>` should be used before
importing any other Kivy modules. Ideally, this means setting them right at
the start of your main.py script.

Alternatively, you can save these settings permanently using
:meth:`Config.set <ConfigParser.set>` then
:meth:`Config.write <ConfigParser.write>`. In this case, you will need to
restart the app for the changes to take effect. Note that this approach will
effect all Kivy apps system wide.

Usage of the Config object
--------------------------

To read a configuration token from a particular section::

    >>> from kivy.config import Config
    >>> Config.getint('kivy', 'show_fps')
    0

Change the configuration and save it::

    >>> Config.set('postproc', 'retain_time', '50')
    >>> Config.write()

For information on configuring your :class:`~kivy.app.App`, please see the
:ref:`Application configuration` section.

.. versionchanged:: 1.7.1
    The ConfigParser should work correctly with utf-8 now. The values are
    converted from ascii to unicode only when needed. The method get() returns
    utf-8 strings.

.. _configuration-tokens:

Available configuration tokens
------------------------------

.. |log_levels| replace::
    'trace', 'debug', 'info', 'warning', 'error' or 'critical'

:kivy:

    `desktop`: int, 0 or 1
        This option controls desktop OS specific features, such as enabling
        drag-able scroll-bar in scroll views, disabling of bubbles in
        TextInput etc. 0 is disabled, 1 is enabled.
    `exit_on_escape`: int, 0 or 1
        Enables exiting kivy when escape is pressed.
        0 is disabled, 1 is enabled.
    `pause_on_minimize`: int, 0 or 1
        If set to `1`, the main loop is paused and the `on_pause` event
        is dispatched when the window is minimized. This option is intended
        for desktop use only. Defaults to `0`.
    `keyboard_layout`: string
        Identifier of the layout to use.
    `keyboard_mode`: string
        Specifies the keyboard mode to use. If can be one of the following:

        * '' - Let Kivy choose the best option for your current platform.
        * 'system' - real keyboard.
        * 'dock' - one virtual keyboard docked to a screen side.
        * 'multi' - one virtual keyboard for every widget request.
        * 'systemanddock' - virtual docked keyboard plus input from real
          keyboard.
        * 'systemandmulti' - analogous.
    `log_dir`: string
        Path of log directory.
    `log_enable`: int, 0 or 1
        Activate file logging. 0 is disabled, 1 is enabled.
    `log_level`: string, one of |log_levels|
        Set the minimum log level to use.
    `log_name`: string
        Format string to use for the filename of log file.

    `log_maxfiles`: int
        Keep log_maxfiles recent logfiles while purging the log directory. Set
        'log_maxfiles' to -1 to disable logfile purging (eg keep all logfiles).

        .. note::
            You end up with 'log_maxfiles + 1' logfiles because the logger
            adds a new one after purging.

    `window_icon`: string
        Path of the window icon. Use this if you want to replace the default
        pygame icon.

:postproc:

    `double_tap_distance`: float
        Maximum distance allowed for a double tap, normalized inside the range
        0 - 1000.
    `double_tap_time`: int
        Time allowed for the detection of double tap, in milliseconds.
    `ignore`: list of tuples
        List of regions where new touches are ignored.
        This configuration token can be used to resolve hotspot problems
        with DIY hardware. The format of the list must be::

            ignore = [(xmin, ymin, xmax, ymax), ...]

        All the values must be inside the range 0 - 1.
    `jitter_distance`: int
        Maximum distance for jitter detection, normalized inside the range 0
        - 1000.
    `jitter_ignore_devices`: string, separated with commas
        List of devices to ignore from jitter detection.
    `retain_distance`: int
        If the touch moves more than is indicated by retain_distance, it will
        not be retained. Argument should be an int between 0 and 1000.
    `retain_time`: int
        Time allowed for a retain touch, in milliseconds.
    `triple_tap_distance`: float
        Maximum distance allowed for a triple tap, normalized inside the range
        0 - 1000.
    `triple_tap_time`: int
        Time allowed for the detection of triple tap, in milliseconds.

:graphics:
    `borderless`: int , one of 0 or 1
        If set to `1`, removes the window border/decoration. Window resizing
        must also be disabled to hide the resizing border.
    `window_state`: string , one of 'visible', 'hidden', 'maximized'
                    or 'minimized'

        Sets the window state, defaults to 'visible'. This option is available
        only for the SDL2 window provider and it should be used on desktop
        OSes.
    `fbo`: string, one of 'hardware', 'software' or 'force-hardware'
        Selects the FBO backend to use.
    `fullscreen`: int or string, one of 0, 1, 'fake' or 'auto'
        Activate fullscreen. If set to `1`, a resolution of `width`
        times `height` pixels will be used.
        If set to `auto`, your current display's resolution will be
        used instead. This is most likely what you want.
        If you want to place the window in another display,
        use `fake`, or set the `borderless` option from the graphics section,
        then adjust `width`, `height`, `top` and `left`.
    `height`: int
        Height of the :class:`~kivy.core.window.Window`, not used if
        `fullscreen` is set to `auto`.
    `left`: int
        Left position of the :class:`~kivy.core.window.Window`.
    `maxfps`: int, defaults to 60
        Maximum FPS allowed.

        .. warning::
            Setting maxfps to 0 will lead to max CPU usage.

    'multisamples': int, defaults to 2
        Sets the `MultiSample Anti-Aliasing (MSAA)
        <http://en.wikipedia.org/wiki/Multisample_anti-aliasing>`_ level.
        Increasing this value results in smoother graphics but at the cost of
        processing time.

        .. note::
           This feature is limited by device hardware support and will have no
           effect on devices which do not support the level of MSAA requested.

    `position`: string, one of 'auto' or 'custom'
        Position of the window on your display. If `auto` is used, you have no
        control of the initial position: `top` and `left` are ignored.
    `show_cursor`: int, one of 0 or 1
        Set whether or not the cursor is shown on the window.
    `top`: int
        Top position of the :class:`~kivy.core.window.Window`.
    `resizable`: int, one of 0 or 1
        If 0, the window will have a fixed size. If 1, the window will be
        resizable.
    `rotation`: int, one of 0, 90, 180 or 270
        Rotation of the :class:`~kivy.core.window.Window`.
    `width`: int
        Width of the :class:`~kivy.core.window.Window`, not used if
        `fullscreen` is set to `auto`.
    `minimum_width`: int
        Minimum width to restrict the window to. (sdl2 only)
    `minimum_height`: int
        Minimum height to restrict the window to. (sdl2 only)
    `min_state_time`: float, defaults to .035
        Minimum time for widgets to display a given visual state.
        This attrib is currently used by widgets like
        :class:`~kivy.uix.dropdown.DropDown` &
        :class:`~kivy.uix.behaviors.buttonbehavior.ButtonBehavior` to
        make sure they display their current visual state for the given
        time.
    `kivy_clock`: one of `default`, `interrupt`, `free_all`, `free_only`
        The clock type to use with kivy. See :mod:`kivy.clock`.

    `default_font`: list
        Default fonts used for widgets displaying any text. It defaults to
        ['Roboto', 'data/fonts/Roboto-Regular.ttf',
        'data/fonts/Roboto-Italic.ttf', 'data/fonts/Roboto-Bold.ttf',
        'data/fonts/Roboto-BoldItalic.ttf'].

    `allow_screensaver`: int, one of 0 or 1, defaults to 1
        Allow the device to show a screen saver, or to go to sleep
        on mobile devices. Only works for the sdl2 window provider.
