Visual Runtime Error On scrolling spinner created in Qml

This is the code in Qml

Code:

This is the Function used In qT FOR qML INTEGRATION

Code:

---

QDeclarativeView *qView=new QDeclarativeView(ui->graphicsView);
 qView->setSource(QString("main.qml"));
 QObject *obj =qView->rootObject();
connect (obj,SIGNAL(titleBarClicked(int,int,int)), this, SLOT(timecal(int,int,int)));

---

Code:

---

void AlarmSet::timecal(int hr1, int min1,int ap1)
{
 
    hra=hr1;
    mina=min1;
    apa=ap1;
  //HERE THE VALUE IS COMING 
}

---

the value is coming in Qt but when we scroll more than five times , the visual runtime error occurs

This Is the Error Displaying At the Qt Console

QGraphicsItem::ungrabMouse: not a mouse grabber
ASSERT: "!implicit" in file graphicsview\qgraphicsscene.cpp, line 906[/B][/B][/SIZE]
