QList<customClass> : can't use QList because "implicitly-deleted copy"

I'm trying to use a QList, a custom class (class Edge:public QGraphicsLineItem), but when I use .append or anything else I got compilation errors

 call to implicitly-deleted copy constructor of 'Edge'
                 current->v = new T(*reinterpret_cast<T*>(src->v));
                                  ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Graphboard.cpp

  void GraphBoard::createEdge()
    {
       
       Edge newEdge(item1,item2);
       edges.append(newEdge);
    
    }

In my GraphBoard.h

QList<Edge> edges;

Maybe I should use *edges here but I get the same error...

I'm doing something wrong with custom class and QList. I already saw this topic Call to implicitly deleted copy constructor but I don't really know what I can take on this.

Here is Edge Defintion, I remove unused stuff:

#include <QObject>
#include <QWidget>
#include <QApplication>
#include <QGraphicsScene>
#include <QGraphicsView>
#include <QGraphicsItem>

class Edge:public QGraphicsLineItem
{

    QGraphicsEllipseItem * state1;
    QGraphicsEllipseItem * state2;

public:
    enum { Type = UserType + 2 };
    int type() const override;
    Edge(QGraphicsEllipseItem * s1, QGraphicsEllipseItem* s2);

     QList<QPointF> centerPoints();

};

You can't get copy of any object in c++ which class don't have a copy constructor. To use pointers is a solution, but writing copy constructor is easy and safe. For more information about copy constructors watch here.
