QGraphicsLayout & QGraphicsObject

[Suths]

Hi,

I'm trying to construct a QGraphicsObject that has behavior from QGraphicsLayout (or actually QGraphicsGridLayout), such that items can be added to it. These child items are custom QGraphicsLayoutItem (& QGraphicItem). However i think i'm getting a bit confused with this approach as i'm not sure what will paint the child objects added via add item.

I constructed a simplified example bellow:

class Box : public QGraphicsObject, public QGraphicsGridLayout
    {
    public:

        Box();

        QRectF boundingRect() const;

        void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = 0);

    };

class Section : public QGraphicsLayoutItem, public QGraphicsItem
    {
    public:
        Section();

        void paint(QPainter* painter, const QStyleOptionGraphicsItem* option, QWidget* widget);

       virtual QSizeF sizeHint(Qt::SizeHint which, const QSizeF &constraint) const;


        void setGeometry(const QRectF &geom);

        QRectF boundingRect() const;

    }

Effectively I want a custom QGraphicsObject that has a grid layout. Can someone help me out with how I could achieve this or even if i'm going about this all wrong.

Thanks

Hi,

What you want to achieve is not really clear. Do you want to obtain with your classes the same thing as a Widget with a QGridLayout and other widgets in that layout ?
