|
* @brief Helper class for PlacesItem to be able to listen to signals
|
|
* and performing a corresponding action.
|
|
*
|
|
* PlacesItem is derived from KStandardItem, which is no QObject-class
|
|
* on purpose. To be able to internally listen to signals and performing a
|
|
* corresponding action, PlacesItemSignalHandler is used.
|
|
*
|
|
* E.g. if the PlacesItem wants to react on accessibility-changes of a storage-access,
|
|
* the signal-handler can be used like this:
|
|
* <code>
|
|
* QObject::connect(storageAccess, SIGNAL(accessibilityChanged(bool,QString)),
|
|
* signalHandler, SLOT(onAccessibilityChanged()));
|
|
* </code>
|
|
*
|
|
* The slot PlacesItemSignalHandler::onAccessibilityChanged() will call
|
|
* the method PlacesItem::onAccessibilityChanged().
