Problem with adding same QWidget in differnt tabs of QTabWidget

[Player]

HI All,
I have created 2 tabs in QTabWidget with QListWidget on each tabs.

//in CustomListWidget.cpp
 #include "CustomListWidget.h"
#include <QDebug> 
 
CustomListWidget::CustomListWidget(QString str , QWidget *parent) :    m_str(str),    QListWidget(parent)
{ 
   listItem = new QListWidgetItem(m_str);
    addItem( listItem );
}
 
void CustomListWidget::sendData(QString &str)
{   
 str = item( 0 )->text();   
 qDebug()<<"the list Widget text is "<<str;
}
 
 // in CTestDlg.cpp
CTestDlg::CTestDlg(QWidget *parent) :    QDialog(parent),    ui(new Ui::CTestDlg)
{   
  ui->setupUi(this);   
     for(int i =1; i<= 2 ; i++ ) 
  {      
 
      customeListWidget = new CustomListWidget(QString::number(i) ); 
 
      connect( this , SIGNAL(getData(QString&)), customeListWidget, SLOT(sendData(QString&)));     
      ui->tabWidget->addTab( customeListWidget, QString("TAB").append(QString::number(i) ) );  
 }
} 
 
void CTestDlg::on_pushButton_clicked()
{   
   QString data; 
   emit getData( data); 
   qDebug()<<"the Data value is "<<data;
}

//in CustomListWidget.cpp
 #include "CustomListWidget.h"
#include <QDebug> 

CustomListWidget::CustomListWidget(QString str , QWidget *parent) :    m_str(str),    QListWidget(parent)
{ 
   listItem = new QListWidgetItem(m_str);
    addItem( listItem );
}

void CustomListWidget::sendData(QString &str)
{   
 str = item( 0 )->text();   
 qDebug()<<"the list Widget text is "<<str;
}

 // in CTestDlg.cpp
CTestDlg::CTestDlg(QWidget *parent) :    QDialog(parent),    ui(new Ui::CTestDlg)
{   
  ui->setupUi(this);   
     for(int i =1; i<= 2 ; i++ ) 
  {      

      customeListWidget = new CustomListWidget(QString::number(i) ); 

      connect( this , SIGNAL(getData(QString&)), customeListWidget, SLOT(sendData(QString&)));     
      ui->tabWidget->addTab( customeListWidget, QString("TAB").append(QString::number(i) ) );  
 }
} 

void CTestDlg::on_pushButton_clicked()
{   
   QString data; 
   emit getData( data); 
   qDebug()<<"the Data value is "<<data;
}

To copy to clipboard, switch view to plain text mode 

Here when i do click the push button by selecting TAb1 or TAb2...

I am always getting the output of

==============================

the list Widget text is “1”
the list Widget text is“2”
the Data value is “2”

Whether i am missing anything here? and may i know..why this duplication is occuring ??
