alias Gio::SettingsGetMapping


The type of the function that is used to convert from a value stored in a #GSettings to a value that is useful to the application.

If the value is successfully mapped, the result should be stored at result and true returned. If mapping fails (for example, if value is not in the right format) then false should be returned.

If value is nil then it means that the mapping function is being given a "last chance" to successfully return a valid value. true must be returned in this case.
