/**
|
|
* @short Provides a means of automatically retrieving, saving and resetting basic settings
|
|
*
|
|
* The KAutoConfig 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).
|
|
*
|
|
* When told to retrieve settings ( retrieveSettings()) KAutoConfig
|
|
* will traverse the specified widgets building a list of all known widgets
|
|
* that have a name and havn't been marked to be ignored.
|
|
* If a setting is marked immutable the value is loaded and the widget is
|
|
* disabled.
|
|
*
|
|
* The name of the widget determines the name of the setting. The initial
|
|
* value of the widget also is the default value when the widget is reset.
|
|
* If the widget does not have a name then it is ignored.
|
|
*
|
|
* When saveSettings() or resetSettings() is called KAutoConfig
|
|
* goes through the list of known widgets and performs the operation on each
|
|
* of them.
|
|
*
|
|
* If one of the widgets needs special treatment it can be specified to be
|
|
* ignored using the ignoreSubWidget() function.
|
|
*
|
|
* KAutoConfig uses the TQSqlPropertyMap class to determine if it can do
|
|
* anything to a widget. Note that KAutoConfig 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 TQ_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
|
|
* TQ_PROPERTY( TQColor color READ color WRITE setColor )
|
|
* \endcode
|
|
*
|
|
* To add KColorButton the following code would be inserted in the main.
|
|
*
|
|
* \code
|
|
* TQSqlPropertyMap *map = TQSqlPropertyMap::defaultMap();
|
|
* map.insert("KColorButton", "color");
|
|
* TQSqlPropertyMap::installDefaultMap(map);
|
|
* \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().
|
|
* If the Apply and Default buttons and enabled/disabled by KAutoConfigDialog
|
|
* automatically then this must be done.
