class header warnings.

[impeteperry]

I am confused obout declaring a class header.
If I daclare a class

class Products: public QWidget
{
Q_OBJECT
public:
Products( QWidget *parent = 0, const char *name = 0);

and the constructor

Products::Products( QWidget *parent, const char *name )
{
}

I get the warnings

products.cpp:40: warning: unused parameter ‘parent’
products.cpp:40: warning: unused parameter ‘name’
products.cpp:40: warning: unused parameter ‘parent’
products.cpp:40: warning: unused parameter ‘name’

I would appreciate some help. thanks
