In header file (*.h) you declare methods and in source file (*.cpp) you write the implementation. Method declarations and implementations have to be in same form, like

Header:

Code:

class MainWindow
{
...
private:
   void processFinished(int code);

Cpp:

Code:

void MainWindow::processFinished(int code)
{
}

Actually you can make the connect without less attributes:

Code:

connect(progress, SIGNAL(finished(int, QString), this, SLOT(progressFinisshed(int));

and it should work.
