In KDE, we don't *use* system(), simply because there are far nicer tools top 
use instead. Use KProcess (see Harry? I'm learning), something like

	KProcess *p = new KProcess();
	p << "appname" << "argument" ;

	QObject::connect(p,SIGNAL(readStdin(QString)),
		this,SLOT(addToOutput(QString)));
	p->run(KProcess::NotifyOnExit,KProcess::All);

This will catch all stdout (ie. cout) messages from that process and hand 
them off to the addToOutput slot.

Note that the code above is pulled out of a hat by me, it may not work as 
written. I'd suggest you read the KProcess documentation (more 
$KDEDIR/include/kprocess.h is enough).
