Equivalent to G_SETTINGS_BIND_GET|G_SETTINGS_BIND_SET
Update the #GObject property when the setting changes. It is an error to use this flag if the property is not writable.
When set in addition to %G_SETTINGS_BIND_GET, set the #GObject property value initially from the setting, but do not listen for changes of the setting
When passed to g_settings_bind(), uses a pair of mapping functions that invert the boolean value when mapping between the setting and the property. The setting and property must both be booleans. You cannot pass this flag to g_settings_bind_with_mapping().
Do not try to bind a "sensitivity" property to the writability of the setting
Update the setting when the #GObject property changes. It is an error to use this flag if the property is not readable.
