A small helper class which blocks an asynchronous operation (e.g. a KIO request)

Example:
...
Synchronizer mSynchronizer;
...

connect( job, SIGNAL( result( KIO::Job * ) ),
SLOT( slotResult( KIO::Job * ) ) );
mSynchronizer.start(); // will block here until the slot was called
...
void slotResult( KIO::Job* )
{
mSynchronizer.stop();
}
