/**
|
|
* @short Provides a means of automatically retrieving,
|
|
* saving and resetting KConfigSkeleton based settings in a dialog.
|
|
*
|
|
* The KConfigDialogManager class provides a means of automatically
|
|
* retrieving, saving and resetting basic settings.
|
|
* It also can emit signals when settings have been changed
|
|
* (settings were saved) or modified (the user changes a checkbox
|
|
* from on to off).
|
|
*
|
|
* The names of the widgets to be managed have to correspond to the names of the
|
|
* configuration entries in the KConfigSkeleton object plus an additional
|
|
* "kcfg_" prefix. For example a widget named "kcfg_MyOption" would be
|
|
* associated to the configuration entry "MyOption".
|
|
*
|
|
* KConfigDialogManager uses the QSqlPropertyMap 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
|
|
* QSqlPropertyMap class. New widgets can be added to the map using
|
|
* QSqlPropertyMap::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( QColor color READ color WRITE setColor )
|
|
* \endcode
|
|
*
|
|
* To add KColorButton the following code would be inserted in the main.
|
|
*
|
|
* \code
|
|
* kapp->installKDEPropertyMap();
|
|
* QSqlPropertyMap *map = QSqlPropertyMap::defaultMap();
|
|
* map->insert("KColorButton", "color");
|
|
* \endcode
|
|
*
|
|
* If you add a new widget to the QSqlPropertyMap and wish to be notified when
|
|
* it is modified you should add its signal using addWidgetChangedSignal().
