QGraphicsTextItem always gets focus once clicked

[EarthHobbit]

I have a QGraphicsView containing a custom QGraphicsTextItem. The QGraphicsTextItem has a double-click event:

void myQGraphicsTextItemClass::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *evt)
{
    MGlobal::displayInfo(MQtUtil::toMString(QString().sprintf("Double click on textId")));
 
    QGraphicsTextItem::mouseDoubleClickEvent(evt);
}

void myQGraphicsTextItemClass::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *evt)
{
    MGlobal::displayInfo(MQtUtil::toMString(QString().sprintf("Double click on textId")));

    QGraphicsTextItem::mouseDoubleClickEvent(evt);
}

To copy to clipboard, switch view to plain text mode 

What goes well:
When I double click in the QGraphicsView but not in the QGraphicsTextItem, then nothing happens, which is normal. When I double click directly on the QGraphicsTextItem, then I get a "Double click on textId" message, as expected.

What goes wrong:
However when I then double click again wherever on my main QGraphicsView but not in the QGraphicsTextItem, then I always get the above message.

Question:
How come the QGraphicsTextItem keeps getting the mouseDoubleClickEvent events even if I am not directly clicking on it ?

My QGraphicsTextItem is created this way from the QGraphicsView constructor:

oneTextNode=new myQGraphicsTextItemClass();
scene()->addItem(oneTextNode);

oneTextNode=new myQGraphicsTextItemClass();
scene()->addItem(oneTextNode);

and my QGraphicsTextItem class looks like:

class myQGraphicsTextItemClass : public QGraphicsTextItem
{
    Q_OBJECT
public:
    myQGraphicsTextItemClass(QGraphicsItem *parent=0);
    virtual ~myQGraphicsTextItemClass() {};
protected:
    virtual void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *evt);
};

class myQGraphicsTextItemClass : public QGraphicsTextItem
{
    Q_OBJECT
public:
    myQGraphicsTextItemClass(QGraphicsItem *parent=0);
    virtual ~myQGraphicsTextItemClass() {};
protected:
    virtual void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *evt);
};

To copy to clipboard, switch view to plain text mode 

and its constructor:

myQGraphicsTextItemClass::myQGraphicsTextItemClass(QGraphicsItem *parent) : QGraphicsTextItem ( parent )
{
        setPlainText("Hello");
        setTextInteractionFlags(Qt::TextEditorInteraction);
}

myQGraphicsTextItemClass::myQGraphicsTextItemClass(QGraphicsItem *parent) : QGraphicsTextItem ( parent )
{
        setPlainText("Hello");
        setTextInteractionFlags(Qt::TextEditorInteraction);
}
