Thanks, I couldnt find any plasma list on lists.kde.org.

Thanks for the replies, I tried playing with the size policies and it
kind of works. This is the code I'm using in the init() method of the
Applet:

if self.containment().formFactor() == Plasma.Vertical:
    self.layout = QGraphicsLinearLayout(Qt.Vertical, self.applet)
    qsp = QSizePolicy(QSizePolicy.Fixed, QSizePolicy.Fixed,
QSizePolicy.PushButton)
else:
    self.layout = QGraphicsLinearLayout(Qt.Horizontal, self.applet)
    qsp = QSizePolicy(QSizePolicy.Fixed, QSizePolicy.Fixed,
QSizePolicy.PushButton)
self.layout.setSpacing(0)
self.applet.setSizePolicy(qsp)
self.applet.setLayout(self.layout)

I'm not quite sure if that's the way I should be doing it because
whenever I set the size policy to anything different than the default
it affects the whole panel the applet goes in. I mean, everything
inside the panel grows beyond the size of the panel just like this
[1]. Using any other policy the icons are again small with gaps in
between, like this [2].
I tried reimplementing the sizeHint method but it never gets called
and I quite dont know what to do there.
