gio.settings_backend
Module for [SettingsBackend] class
Types 3
The [gio.settings_backend.SettingsBackend] interface defines a generic interface for non-strictly-typed data that is stored in a hierarchy. To implement an alternative storage backend for [gio.settings.Settings], you need to implement the [gio.settings_backend.SettingsBackend] interface and then make it implement the extension point [gio.types.SETTINGS_BACKEND_EXTENSION_POINT_NAME].
The interface defines methods for reading and writing values, a method for determining if writing of certain values will fail (lockdown) and a change notification mechanism.
The semantics of the interface are very precisely defined and implementations must carefully adhere to the expectations of callers that are documented on each of the interface methods.
Some of the [gio.settings_backend.SettingsBackend] functions accept or return a [glib.tree.Tree]. These trees always have strings as keys and [glib.variant.Variant] as values.
The [gio.settings_backend.SettingsBackend] API is exported to allow third-party implementations, but does not carry the same stability guarantees as the public GIO API. For this reason, you have to define the C preprocessor symbol G_SETTINGS_ENABLE_BACKEND before including gio/gsettingsbackend.h.
SettingsBackend self()Returns `this`, for use in `with` statements.SettingsBackendGidBuilder builder()Get builder for [gio.settings_backend.SettingsBackend] Returns: New builder objectgio.settings_backend.SettingsBackend getDefault()Returns the default #GSettingsBackend. It is possible to override the default by setting the `GSETTINGS_BACKEND` environment variable to the name of a settings backend.void changed(string key, void * originTag = null)Signals that a single key has possibly changed. Backend implementations should call this if a key has possibly changed its value.void keysChanged(string path, string[] items, void * originTag = null)Signals that a list of keys have possibly changed. Backend implementations should call this if keys have possibly changed their values.void pathChanged(string path, void * originTag = null)Signals that all keys below a given path may have possibly changed. Backend implementations should call this if an entire path of keys have possibly changed their values.void pathWritableChanged(string path)Signals that the writability of all keys below a given path may have changed.void writableChanged(string key)Signals that the writability of a single key has possibly changed.Fluent builder for [gio.settings_backend.SettingsBackend]
