[Qt-interest] QTableWidget: cannot insert an item that is already owned by another QTableWidget

[Malyushytsky, Alex]

The problem is explained in the error message you get.
One of the solution is to

Move:
    item_trackNo     = new QTableWidgetItem();
before:

    item_trackNo->setText(trackId);////trackId);

Subject: [Qt-interest] QTableWidget: cannot insert an item that is already owned by another QTableWidget

Hi All,
I am using QTableWidget for creating a table. while inserting QTableWdgetItem into table it's showing an error  like bellow.
 "QTableWidget: cannot insert an item that is already owned by another QTableWidget ".

Here is my source code.
#include "HookWindow.h"
hookWindow::hookWindow(QWidget* parent, Qt::WFlags fl): QWidget (parent,fl)
{

    label_msg = new QLabel("  Hook Window ",this);

     _tableHookWindow = new QTableWidget(10,5,this);

    item_trackNo     = new QTableWidgetItem();


}
////////////////////////////////////////////////////////////////////////
hookWindow::~hookWindow(void)
{

}
////////////////////////////////////////////////////////////////////////
void hookWindow::createHookWindow(int width,int height)
{
    //label_msg = new QLabel("  Hook Window ",this);
    label_msg->setGeometry(2,0,width,30);
    label_msg->show();
    QFont font("Helvetica", 15, QFont::Bold);
    label_msg->setFont(font);


    //_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->setColumnWidth( 3,width/5 );
    _tableHookWindow->setColumnWidth( 4,width/5 );
    _tableHookWindow->show();

    _addLabel<<"Track No" <<"Speed"<<"Height"<<"Hdng"<<"Idty";
    _tableHookWindow->setHorizontalHeaderLabels(_addLabel );



}

void hookWindow::slot_getHookWindowData(int track_id)
{

    trackId = QString::number(track_id);
    cout<<"track_id from hookWindow::"<<trackId.toAscii().data() <<endl;


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

}
Can anyone please suggest me what can be the solution.
Any help is appreciated.
