For example a widget named "kcfg_MyOption" would be + * associated to the configuration entry "MyOption". + * + * KConfigDialogManager uses the TQSqlPropertyMap class to determine if it can do + * anything to a widget. Note that KConfigDialogManager doesn't require a + * database, it simply uses the functionality that is built into the + * TQSqlPropertyMap class. New widgets can be added to the map using + * TQSqlPropertyMap::installDefaultMap(). Note that you can't just add any + * class. The class must have a matching Q_PROPERTY(...) macro defined. + * + * For example (note that KColorButton is already added and it doesn't need to + * manually added): + * + * kcolorbutton.h defines the following property: + * \code + * Q_PROPERTY( TQColor color READ color WRITE setColor ) + * \endcode + * + * To add KColorButton the following code would be inserted in the main. + * + * \code + * kapp->installKDEPropertyMap(); + * TQSqlPropertyMap *map = TQSqlPropertyMap::defaultMap(); + * map->insert("KColorButton", "color"); + * \endcode + * + * If you add a new widget to the TQSqlPropertyMap and wish to be notified when + * it is modified you should add its signal using addWidgetChangedSignal(). + + * @since 3.2 + * @author Benjamin C Meyer + * @author Waldo Bastian + */ +class KDECORE_EXPORT KConfigDialogManager : public TQObject { + +Q_OBJECT + +signals: + /** + * One or more of the settings have been saved (such as when the user + * clicks on the Apply button).
