Slot not being called when QFutureWatcher is finished

[stampede]

Signal and slot signature does not match, you should get a warning message about connect statement - you cannot connect a signal with no parameters to a slot expecting a parameter, because what should be the parameter value inside the slot when signal is delivered ?
This should work:

connect(watcher,SIGNAL(finished()),this,SLOT(copyComplete()));
// and change the slot:
void ViewerMain::copyComplete()
{
    qDebug("Copy complete fired!");
}

connect(watcher,SIGNAL(finished()),this,SLOT(copyComplete()));
// and change the slot:
void ViewerMain::copyComplete()
{
    qDebug("Copy complete fired!");
}
