neglecting for a while how actually give focus to the panel, api-wise on 
plasma side could work as this:
Applet::addFocusWidget(QGraphicsWidget *)
it's usedto add widgets that are supposed to request focus when clicked, 
thinking about it maybe we want addFocusWidgets(QList<QGraphicsWidget *>)

for each one of those widgets applet adds and eventfilter (ugh!) monitoring 
the focusin events, in this case emits a signal that gets forwarded up to the 
containment up to the view and in this case the view will get focus

hmm, maybe still a bit twisted, can still be smoothed a little bit
