Trouble with QGraphicsTextItem events

[Flippik]

Hi2all! I need to work some event when user clicks or gets mouse over the QGraphicsTextItem. I'm trying to do it this way,but nothing happens/events do not work.

// myScene.h
#include <QSound>
#include <QGraphicsScene>
 
class myScene : public QGraphicsScene
{
    Q_OBJECT
public:
    móScene(QObject *parent = 0);
    QSound *menuSound,*cSound;
 
private slots:
    void start();
};
//myScene.cpp
myScene::myScene(QObject *parent) : QGraphicsScene(parent)
{ 
     QPalette p;
     setBackgroundBrush(QPixmap(":/data/bg.png"));
     QGraphicsTextItem* stLabel3 = addText(trUtf8("smth"));
     //stLabel3->setHtml(trUtf8("smth"));
     stLabel3->setFlag(QGraphicsItem::ItemIsMovable);
     stLabel3->setPos(275,260);
     stLabel3->setDefaultTextColor(QColor(0,43,0,127));
     stLabel3->setFont(QFont("Comic Sans MS", 24, QFont::Bold,QFont::StyleItalic));
     stLabel3->adjustSize();
     stLabel3->setZValue(1);
    QTransform transform = stLabel3->transform();
     transform.rotate(80.0, Qt::YAxis);
     transform.scale(2., 1.5);
     stLabel3->setTransform(transform);
     stLabel3->setTextInteractionFlags(Qt::LinksAccessibleByMouse);
     connect(stLabel3,SIGNAL(linkActivated(const QString&)),this,SLOT(start()));
 
 
    menuSound = new QSound("data/sound/menu.wav");
    cSound = new QSound("data/sound/mus_w1.wav");
    menuSound->play();
}
 
 
void myScene::start()
{
menuSound->stop();
cSound->play();
}

// myScene.h
#include <QSound>
#include <QGraphicsScene>

class myScene : public QGraphicsScene
{
    Q_OBJECT
public:
    móScene(QObject *parent = 0);
    QSound *menuSound,*cSound;

private slots:
    void start();
};
//myScene.cpp
myScene::myScene(QObject *parent) : QGraphicsScene(parent)
{ 
     QPalette p;
     setBackgroundBrush(QPixmap(":/data/bg.png"));
     QGraphicsTextItem* stLabel3 = addText(trUtf8("smth"));
     //stLabel3->setHtml(trUtf8("smth"));
     stLabel3->setFlag(QGraphicsItem::ItemIsMovable);
     stLabel3->setPos(275,260);
     stLabel3->setDefaultTextColor(QColor(0,43,0,127));
     stLabel3->setFont(QFont("Comic Sans MS", 24, QFont::Bold,QFont::StyleItalic));
     stLabel3->adjustSize();
     stLabel3->setZValue(1);
    QTransform transform = stLabel3->transform();
     transform.rotate(80.0, Qt::YAxis);
     transform.scale(2., 1.5);
     stLabel3->setTransform(transform);
     stLabel3->setTextInteractionFlags(Qt::LinksAccessibleByMouse);
     connect(stLabel3,SIGNAL(linkActivated(const QString&)),this,SLOT(start()));


    menuSound = new QSound("data/sound/menu.wav");
    cSound = new QSound("data/sound/mus_w1.wav");
    menuSound->play();
}


void myScene::start()
{
menuSound->stop();
cSound->play();
}
