Signal and "already defined" error

I have a strange problem: there is a method "onprogress" in the class below. During link I am getting an error of it being already defined. When I remove "signals:" keyword it compiles OK. What might be the offence? (Windows, vs2008)

Code:

---

class btprogress : public QDialog
{
	Q_OBJECT
 
public:
	btprogress (nbt& nt, boost::gregorian::date mindate, boost::gregorian::date maxdate, 
	QWidget*parent = 0);
	~btprogress();
 
signals:
	void onprogress(QString date);
 
private slots:
	void onbtcanceled();
	void oncancel();
}

Check your code for onprogress texts,, may be you are defining it elsewhere too.
BTW, in you code does the class have semi colon at end ?

try to rename the signal.

Thank you guys, for the help.

Yes, there is a semicolon at the end. No, there is no "onprogress" method/free function/etc anywhere in the project. I will rename signal and see what happens.
