Hi, I am trying to create a Custom QGraphicsItem button as shown by Fred here. The code which he posted can be found here.

The problem is when I try and compile the code I get the following two errors:

• /usr/include/qt4/QtGui/qgraphicsitem.h ‘QGraphicsItem::QGraphicsItem(const QGraphicsItem&)’ is private
• /usr/include/qt4/QtCore/qobject.h
  ‘QObject::QObject(const QObject&)’ is private

Here is the code snippet which essentially is the same as that in the sample above. The error is on the class deceleration.

class MyButton : public QObject, public QGraphicsItem
{
 Q_OBJECT
 Q_INTERFACES(QGraphicsItem)

public:
 MyButton(QGraphicsItem *parent = 0);
 MyButton(const QString normal, const QString pressed = "", QGraphicsItem *parent = 0);
....
}

Interestingly the other sample as shown here works fine. The sample code for that can be found here.

Any idea what is wrong? Thanks in advance.
