See man xfconf-query(1). type: list elements: raw value_type: description: - The type of value being set. - When providing more than one I(value_type), the length of the list must be equal to the length of I(value). - If only one I(value_type) is provided, but I(value) contains more than on element, that I(value_type) will be applied to all elements of I(value). - If the I(property) being set is an array and it can possibly have ony one element in the array, then I(force_array=true) must be used to ensure that C(xfconf-query) will interpret the value as an array rather than a scalar. - Support for C(uchar), C(char), C(uint64), and C(int64) has been added in community.general 4.8.0. type: list elements: str choices: [ string, int, double, bool, uint, uchar, char, uint64, int64, float ] state: type: str description: - The action to take upon the property/value. - The state C(get) has been removed in community.general 5.0.0.
