short_description: Edit XFCE4 Configurations
description:
- This module allows for the manipulation of Xfce 4 Configuration via
xfconf-query. Please see the xfconf-query(1) man pages for more details.
options:
channel:
description:
- A Xfconf preference channel is a top-level tree key, inside of the
Xfconf repository that corresponds to the location for which all
application properties/keys are stored. See man xfconf-query(1)
required: yes
property:
description:
- A Xfce preference key is an element in the Xfconf repository
that corresponds to an application preference. See man xfconf-query(1)
required: yes
value:
description:
- Preference properties typically have simple values such as strings,
integers, or lists of strings and integers. This is ignored if the state
is "get". See man xfconf-query(1)
value_type:
description:
- The type of value being set. This is ignored if the state is "get".
choices: [ int, bool, float, string ]
state:
description:
- The action to take upon the property/value.
choices: [ get, present, absent ]
default: "present"
