QFutureWatcher signals not firing

[nwest]

Has anyone had problems with QFutureWatcher signals not firing? Here's the code:

QFutureWatcher<void> watcher;
 
connect(&watcher, SIGNAL(progressRangeChanged(int, int)), this,  SLOT(progressRangeChanged(int, int)));
connect(&watcher, SIGNAL(progressValueChanged(int)), this, SLOT(progressValueChanged(int)));
connect(&watcher, SIGNAL(finished()), this, SLOT(finished()));
 
QFuture<dent_vec_t> dent_scan_future = QtConcurrent::mappedReduced(all_joint_scan_params,dent_scan_with_line,&combine_dent_lists);
watcher.setFuture(dent_scan_future);
while (!watcher.isFinished())
{
	//Some debug code
	int prog1 = watcher.progressMinimum();
	int prog2 = watcher.progressMaximum();
	int progValue = watcher.progressValue();		
}	
m_dents = dent_scan_future.result();

QFutureWatcher<void> watcher;
	
connect(&watcher, SIGNAL(progressRangeChanged(int, int)), this,  SLOT(progressRangeChanged(int, int)));
connect(&watcher, SIGNAL(progressValueChanged(int)), this, SLOT(progressValueChanged(int)));
connect(&watcher, SIGNAL(finished()), this, SLOT(finished()));

QFuture<dent_vec_t> dent_scan_future = QtConcurrent::mappedReduced(all_joint_scan_params,dent_scan_with_line,&combine_dent_lists);
watcher.setFuture(dent_scan_future);
while (!watcher.isFinished())
{
	//Some debug code
	int prog1 = watcher.progressMinimum();
	int prog2 = watcher.progressMaximum();
	int progValue = watcher.progressValue();		
}	
m_dents = dent_scan_future.result();

I threw in the debug code to see if there's any progress to report, and there is. Here are my slots:

Header:

public slots:
	void finished();
	void progressRangeChanged(int, int);
	void progressValueChanged(int);

public slots:
	void finished();
	void progressRangeChanged(int, int);
	void progressValueChanged(int);

CPP:

void dent_scanner::finished()
{
	cout<<"FINISHED"<<endl;
}
 
void dent_scanner::progressRangeChanged(int a, int b)
{
	cout<<"PROGRESS RANGE CHANGED: " <<a<<", "<<b<<endl;
}
 
void dent_scanner::progressValueChanged(int a)
{
	cout<<"PROGRESS VALUE CHANGED: " <<a<<endl;
}

void dent_scanner::finished()
{
	cout<<"FINISHED"<<endl;
}

void dent_scanner::progressRangeChanged(int a, int b)
{
	cout<<"PROGRESS RANGE CHANGED: " <<a<<", "<<b<<endl;
}

void dent_scanner::progressValueChanged(int a)
{
	cout<<"PROGRESS VALUE CHANGED: " <<a<<endl;
}

This code won't execute no matter what I do. I have the Q_OBJECT macro in the header, and the moc file included at the bottom. The class inherits from QOBject. No errors print out when I connect up the signals and slots (already fixed that problem...)

I can usually find my way around signals and slots just fine. I probably just made a stupid mistake, but can't seem to figure out what it is. Any thoughts?

Are you sure the following line is correct?

QFutureWatcher<void> watcher;

QFutureWatcher<void> watcher;

Shouldn't that be the the following line?

QFutureWatcher<dent_vec_t> watcher;

QFutureWatcher<dent_vec_t> watcher;
