hmm.. but there is an scene event filter placed on the widget in 
ExtenderItem::setWidget, and ExtenderItem::sceneEventFilter should be reacting 
to resize events on the widget.

hmm... can you put some debug output in ExtenderItem::sceneEventFilter and run 
the network manager in plasmoidviewer to see what happens?

note that while ExtenderItem::setWidget takes a QGraphicsItem, only 
QGraphicsWidgets actually create resize events. i assume that the nm plasmoid 
is using a QGraphicsWidget, however.
