[Qt-interest] QTableWidget segmentation fault

[Bijay Panda]

Hi All,
I am using a QTableWidget in my application.When i click a widget(which is a
QgisMap Canvas from another class) a signal emitted sending a integer.I am
trying to put tha data in to a call of the table .The problem is when I
click that canvas i m getting the proper data here inside the slot.But when
i m trying to put that data in the table inside the same slot, it's giving
segmentation fault.Here is my code

void hookWindow:: createTable()
{
   _tableHookWindow = new QTableWidget(10,5,this);

_tableHookWindow->setGeometry(1,label_msg->y()+label_msg->height(),width,height-label_msg->height());

    _tableHookWindow->setColumnWidth( 0,width/4.5);
    _tableHookWindow->setColumnWidth( 1,width/5 );
    _tableHookWindow->setColumnWidth( 2,width/5 );
      _tableHookWindow->show();

    _addLabel<<"Track No" <<"Speed"<<"Height"<<"Hdng"<<"Idty";
    _tableHookWindow->setHorizontalHeaderLabels(_addLabel );
    item_trackNo= new QTableWidgetItem(QTableWidgetItem::Type);

    item_trackSpeed  = new QTableWidgetItem(QTableWidgetItem::Type);
}

void hookWindow::slot_getHookWindowData(int obj_id)
{

    trackId = QString::number(obj_id);
    cout<<"obj_id::"<<trackId.toAscii().data() <<endl;
//   Here i am getting  proper data when i click the widget

   item_trackNo->setText(trackId);
   _tableHookWindow->setItem(0,0,item_trackNo);


}
I tried it by putting hard core value also giving segmentation fault
But if i am setting value inside create table() then it's not a problem
there.
I want to set values to table inside that slot which collect values from
anothe class.
Can anyone please help me out.
