Creating a list of QGraphicsItems

[schmimona]

Hi,

I have a QGraphicsScene on which I would like to draw some special curves. I made a class in which I define these special curves as a new QGraphicsItem:

class Clothoid : public QGraphicsItem
{
public:
    Clothoid(QPoint startPoint, QPoint endPoint);
    virtual ~Clothoid();
...
 
protected:
    QRectF boundingRect() const;
    void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget);
 
};

class Clothoid : public QGraphicsItem
{
public:
    Clothoid(QPoint startPoint, QPoint endPoint);
    virtual ~Clothoid();
...

protected:
    QRectF boundingRect() const;
    void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget);

};

To copy to clipboard, switch view to plain text mode 

and I try to insert each item twice: once in an array I defined:

QList<Clothoid *> clothoids;

QList<Clothoid *> clothoids;

To copy to clipboard, switch view to plain text mode 

and once in the scene:

void renderArea::updateClothoid(const QPoint &p1, const QPoint &p2)
{
    Clothoid *temp = new Clothoid(p1, p2);
 
    clothoids.append(&temp);
 
    scene->addItem(&temp);
}

void renderArea::updateClothoid(const QPoint &p1, const QPoint &p2)
{
    Clothoid *temp = new Clothoid(p1, p2);

    clothoids.append(&temp);

    scene->addItem(&temp);
}

To copy to clipboard, switch view to plain text mode 

But I get these 2 errors:

no matching function for call to 'QList<Clothoid*>::append(Clothoid**)'

and

no matching function for call to 'QGraphicsScene::addItem(Clothoid**)'

What am I doing wrong?

Skip the &. And by the way the error message is telling you all you need to know...
