you will need to implement your own slot.

if you are looking for an example, see 
kdebase/workspace/plasma/applets/analog-clock/clock.h and search for "slots". 
also note in the .cpp file how there is a #include "clock.moc" at the bottom of 
the file which makes the slot magic work.

if you wish to see your cpu speed, then you probably want to use the 
systemmonitor dataengine, something like this in your init():

dataEngine("systemmonitor")->connectSource("cpu/cpu0/clock", this, 1000);

and then create a dataUpdated(const QString &sourceName, const 
Plasma::DataEngine::Data &data) slot in your Applet.
