KNotifications and the system tray

[Will Stephenson]

In KDE 3, Kopete used to show notifications (passive popups mainly) adjacent 
to its system tray icon.  In KDE 4 this is no longer possible because the 
KSystemTray is no longer a QWidget, so it doesn't have a winId() method, nor 
can it be passed to KNotification::event( QWidget *, ... );

What was the background to this change (portability) and what is the way to do 
it now instead?  The requirement to notify at/near a systray icon is still 
present.
