+/**
+ @short Class for handling preferences settings for an application.
+ @author Cornelius Schumacher
+ @see KPrefsItem
+
+ This class provides an interface to preferences settings. Preferences items
+ can be registered by the addItem() function corresponding to the data type of
+ the seetting. KPrefs then handles reading and writing of config files and
+ setting of default values.
+
+ Normally you will subclass KPrefs, add data members for the preferences
+ settings and register the members in the constructor of the subclass.
+
+ Example:
+ <pre>
+ class MyPrefs : public KPrefs {
+ public:
+ MyPrefs()
+ {
+ setCurrentGroup("MyGroup");
+ addItemBool("MySetting1",&mMyBool,false);
+ addItemColor("MySetting2",&mMyColor,QColor(1,2,3));
+
+ setCurrentGroup("MyOtherGroup");
+ addItemFont("MySetting3",&mMyFont,QFont("helvetica",12));
+ }
+
+ bool mMyBool;
+ QColor mMyColor;
+ QFont mMyFont;
+ }
+ </pre>
+
+ It might be convenient in many cases to make this subclass of KPrefs a
+ singleton for global access from all over the application without passing
+ references to the KPrefs object around.
+
+ You can set all values to default values by calling @ref setDefaults(), write
+ the data to the configuration file by calling @ref writeConfig() and read the
+ data from the configuration file by calling @ref readConfig().
+
+ If you have items, which are not covered by the existing addItem() functions
+ you can add customized code for reading, writing and default setting by
+ implementing the functions @ref usrSetDefaults(), @ref usrReadConfig() and
+ @ref usrWriteConfig().
+
+ Internally preferences settings are stored in instances of subclasses of
+ @ref KPrefsItem. You can also add KPrefsItem subclasses for your own types
+ and call the generic @ref addItem() to register them.
