Beginner C++ question

[masoroso]

I hope someone finds the time to answer my C++ beginner question!

I `designed' a new class around the QPixMap like this:

class Image : public QPixmap
{
private:
  int m_x;
  int m_y;
  QString m_fileName;
 
public:
  Image( const QString &filename, int x, int y );
 
};

class Image : public QPixmap
{
private:
  int m_x;
  int m_y;
  QString m_fileName;

public:
  Image( const QString &filename, int x, int y );

};

To copy to clipboard, switch view to plain text mode 

It only adds some new properties to the class.

Then I wrote another class that contains a list of these classes

class Map : public QWidget
{
  Q_OBJECT
 
private:
  QList<Image *> m_imageList;
 
public:
  Map( QWidget *parent=0 );
...
protected:
  void paintEvent(QPaintEvent*);
 
};

class Map : public QWidget
{
  Q_OBJECT

private:
  QList<Image *> m_imageList;

public:
  Map( QWidget *parent=0 );
...
protected:
  void paintEvent(QPaintEvent*);

};

To copy to clipboard, switch view to plain text mode 

In the paintEvent function I want to draw the Images to the screen but I don't know how to do that How can I use the drawPixmap function to draw the pixmap in the Image class??

This is my (erronous) code to drawthe first image

void Map::paintEvent(QPaintEvent*)
{
  if(m_imageList.count() > 0){
    QPainter p( this );
    p.save();
    p.drawPixmap( 0, 0, m_imageList.first());  <= ERROR
    p.restore();
  }
}

void Map::paintEvent(QPaintEvent*)
{
  if(m_imageList.count() > 0){
    QPainter p( this );
    p.save();
    p.drawPixmap( 0, 0, m_imageList.first());  <= ERROR
    p.restore();
  }
}

To copy to clipboard, switch view to plain text mode 

Could I just cast the Image to a Pixmap class? And if so, how?

Thanks in advance.. the inheritance options in C++ still confuse me
