i see a veeery weird problem with that (used also in Plasma::PushButton)
the buttons gets painted without problems when the applet is on the desktop 
but on the panel don't get painted at all!
i find the problem in qpushbuttons and qlineedits with qtextedit/ktextedit the 
text is painted fine (but never the box around the textbox)
with qpushbuttons the button icon gets painted when the button is pressed.
removing setAttribute(Qt::WA_NoSystemBackground); fixes the problem (but 
leaving of course the ugly gray box)
i really don't know what to think anymore, i suspect something with argb 
visuals?, boooh :(
could it be probably some obscure qt bug?

Cheers,
