How can I invoke the member funcions of QTableViewPrivate?

Hi
I want to inherit QTableView and invoke some QTableViewPrivate member functions.

.h file

Code:

---

#include <QTableView>
#include <QTableView>
class SpreadsheetPrivate;
class Spreadsheet : public QTableView
{
  Q_OBJECT
public: 
  Spreadsheet();
  void test(); 
protected:
private: 
  Q_DECLARE_PRIVATE(Spreadsheet)
};

---

.cpp file

Code:

---

#include <QtGui>
#include <private/qtableview_p.h>
#include "Spreadsheet.h"
class SpreadsheetPrivate: public QTableViewPrivate
{
};
Spreadsheet::Spreadsheet()
{
}
void Spreadsheet::test()
{
  Q_D(Spreadsheet);
  //The problem come here
}

---

The Problem is that when I use fields or inline functions of QTableViewPrivate,it works fine.When I try to invoke the member functions(not inline functions) of QTableViewPrivate,I can compile the code,however,it will show a error while linking like this:
undefined reference to 'QTableViewPrivate::xxxxx'
Can anyone tell me what's wrong with it?How can I do to invoke the member functions of QTableViewPrivate?
thanks.

IMHO the problem is conceptual. you cannot use xxxPrivate members.

When you installs Qt the <*_p.h> includes are not available
