.. _org.freedesktop.impl.portal.Settings Description:

Settings portal backend interface

This interface provides read-only access to a small number
of host settings required for toolkits similar to XSettings.
It is not for general purpose settings.

Currently the interface provides the following keys:

* ``org.freedesktop.appearance`` ``color-scheme`` (``u``)

  Indicates the system's preferred color scheme.
  Supported values are:

  - ``0``: No preference
  - ``1``: Prefer dark appearance
  - ``2``: Prefer light appearance

  Unknown values should be treated as 0 (no preference).

* ``org.freedesktop.appearance`` ``accent-color`` (``(ddd)``)

  Indicates the system's preferred accent color as a tuple of RGB values
  in the sRGB color space, in the range [0,1].
  Out-of-range RGB values should be treated as an unset accent color.

* ``org.freedesktop.appearance``  ``contrast`` (``u``)

  Indicates the system's preferred contrast level.
  Supported values are:

  - ``0``: No preference (normal contrast)
  - ``1``: Higher contrast

  Unknown values should be treated as 0 (no preference).

Implementations can provide other keys; they are entirely
implementation details that are undocumented. If you are a
toolkit and want to use this please open an issue.

Note that the Settings portal can operate without this backend,
implementing it is optional.
