Applet::dataEngine is guaranteed to return a non-null pointer; it may return a 
non-valid engine, but mEngine will never be null.


mEngine->connectSource("test01applet", this);
dataUpdated("test01applet", mEngine->query("test01applet"));

the dataUpdated call should also not be necessary. upon first connect 
dataUpdated will be called if there is any data to respond to.

in your code i see this:

	setDrawStandardBackground(true);

that's the old api. however in your engine:

	sourceRequestEvent( const QString &name )

that's the new api!

so evidently you're mixing old and new api, therefore your problems =) in the 
old api, DataEngine::sourceRequestEvent was DataEngine::sourceRequested.

what version of libplasma are you developing against?
