Get correct QGraphicsItem



  • I have a custom class derived from QGraphicsItem. In that class I have private data member which is QGraphicsSvgItem. In my custom class constructor I am creating a QGraphicsSvgItem and its parent as my custom class. Below what I did.

    @class CustomItem : public QGraphicsItem
    {
    private:
    QGraphicsSvgItem *svgItem;
    }

    CustomItem::CustomItem()
    {
    svgItem = new QGraphicsSvgItem(fileName,this);
    }
    @

    Besides this I have another class(CustomItem2). With this class I am filtering CustomItem events.(I set all my CustomItems parent as CustomItem2)
    When CustomItem2 filters an event which belongs to CustomItem i can't get information about CustomItem because the watched object returns as QGraphicsSvgItem.
    But i want the object return as CustomItem.
    How can I solve this?



  • You can solve this by making CustomItem a QGraphicsSvgItem:

    @ class CustomItem : public QGraphicsSvgItem
    {
    ...
    };

    CustomItem::CustomItem(QGraphicsItem *parent) :
    QGraphicsSvgItem(fileName, parent)
    {

    }@
