The notifications are part of Mylyn commons.

To integrate them, add the Mylyn Commons Notifications feature from http://download.eclipse.org/mylyn/releases/latest to your target platform definition. The relevant bundles are

• org.eclipse.mylyn.commons.notifications.ui
• org.eclipse.mylyn.commons.notifications.core.

You can add a category and an event to the notifications extension point like this:

</extension>
  <extension
        point="org.eclipse.mylyn.commons.notifications.ui.notifications">
     <category
           icon="icons/obj16/repository.gif"
           id="myNotificationCategory"
           label="My Category">
     </category>
     <event
           categoryId="myNotificationCategory"
           icon="icons/obj16/some-image.gif"
           id="myEvent"
           label="Hello World">
        <defaultHandler
              sinkId="org.eclipse.mylyn.commons.notifications.sink.Popup">
        </defaultHandler>
        <description>
          This is the description of the event.
        </description>
     </event>
</extension>

To trigger a notification, use the NotificationService like this:

AbstractUiNotification notification = ...
NotificationsUi.getService().notify( asList( notification ) );

The notification must be a subclass of AbstractUiNotification where the eventId passed to the constructor must match the one from the extension.

The notifications plug-in also adds a preference page under General > Notifications that lets the user choose which notifications should be shown.

No, but you can use the plugin org.eclipse.mylyn.commons.ui, which contains interesting classes to display notification(s) at the bottom right of the screen.
