an object property to a particular configuration key. GSettings offers this service itself. </p> <p> There is a pattern that is sometimes used for GConf, where a setting can have explicit 'value A', explicit 'value B' or 'use the system default'. With GConf, 'use the system default' is sometimes implemented by unsetting the user value. </p> <p> This is not possible in GSettings, since it does not have API to determine if a value is the default and does not let you unset values. The recommended way (and much clearer) way in which this can be implemented in GSettings is to have a separate 'use-system-default' boolean setting. </p> </div> <div class="footer"> <hr>Generated by GTK-Doc V1.32</div> </body> </html>
