+Notification
+============
+
+Notifications are a way to inform users of your app about events, even if the 
+applications has no focus, is minimized, or is only running in the background.
+
+Examples
+--------
+
+.. figure:: /img/Notification.png
+   :alt: 
+   
+   Update notification 
+
+Guidelines
+----------
+
+Is this the right control
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Use notifications to inform the user of events that are of interest, even if 
+your app is not in foreground, but don't spam the user with notifications.
+
+ - Completion of long running tasks that the user has started manually
+ - Incoming communication from other users
+ - Hardware related events like low battery, lost network connection, running 
+   out of disk space
+ 
+
+Don't use a notification for:
+
+ - Operations that don't require user interaction, such as background processes, 
+   syncing, or updates
+ - Advertising, rating or feedback requests, or other annoyances
+ - If an unexpected or potentially dangerous condition has been reached and the 
+   user must make a decision. Use an :doc:`/components/assistance/message` 
+   instead.
+ - Don't send notifications if an user has never opened your application
+
+Behavior
+~~~~~~~~
+
+Notifications are provided by the system to the user, and foremost the 
+user settings for notification govern the behavior and appearance of 
+notifications. But there are several options to influence and enrich the 
+behavior of your notifications.
+
+Persistence
+"""""""""""
+
+Making a notification persistent will prevent it from closing after a timeout. 
+Your app must revoke the persistent notification, if the reason for the 
+notification no longer applies, like a power adapter was plugged after a 
+"Laptop battery is almost empty" notification.
+
+Urgency
+"""""""
+
+It is recommended that a notification carrys an urgency hint:
+
+ - 0 – Low, “Matt is now online”, “You just plugged in your AC adapter”
+ - 1 – Normal, “You have new mail”
+ - 2 – Critical, “Laptop battery is almost empty”
+
+Actions
+"""""""
+
+You can add up to three action buttons to the notification to enable the user 
+to react to the event without having to go to the app itself.
+
+Preview
+"""""""
+
+You can specify a URL to an image associated with the notification. The image 
+will be displayed as a preview in the notification.
+
+.. figure:: /img/Notification2.png
+   :alt: 
+   
+   Notification with a preview image
+   
+.. Quick Reply
+   """""""""""
+
+   This enables the user to reply to an email or SMS from within the 
+   notification. A “Reply” text field is placed in the notification window 
+   whose content is eventually sent back to the application through the 
+   notification server.
+
+Code
+----
+
+.. code-block:: c++
+
+    KNotification *notification= new KNotification ( "contactOnline", widget );
+    notification->setText( i18n("The contact %1 has gone online", 
+    contact->name() );
+    notification->setPixmap( contact->pixmap() );
+    notification->setActions( QStringList( i18n( "Open chat" ) ) );
+    connect(notification, SIGNAL(activated(unsigned int )), contact , 
+    SLOT(slotOpenChat()) );
+    notification->sendEvent();
+
+Use :knotificationsapi:`<KNotification>` to send notifications to the
+:doc:`Plasma Workspaces </introduction/architecture>`.
