sorry for taking a long time to reply

I have something like this

.cpp
Qt Code: 
  1. #include "mainwindow.h"
  2. #include "ui_mainwindow.h"
  3.  
  4. QStringList lst_ListItems;
  5. MainWindow::MainWindow(QWidget *parent) :    QMainWindow(parent),    ui(new Ui::MainWindow)
  6. {
  7.     ui->setupUi(this);
  8.  
  9.     lst_ListItems.append("QtBlog");
  10.     lst_ListItems.append("QtCenter");
  11.     lst_ListItems.append("QtCreator");
  12.     lst_ListItems.append("QtDesigner");
  13.     lst_ListItems.append("Wildcard");
  14.  
  15.     for(int iIndex = 0; iIndex < lst_ListItems.count(); ++iIndex)
  16.     {
  18.         pItem->setText(lst_ListItems.at(iIndex));
  19.         ui->lstNamesControl->addItem(pItem);// lstNamesControl is a QListWidget
  20.     }
  21. }
  22.  
  23. MainWindow::~MainWindow()
  24. {
  25.     delete ui;
  26. }
  27.  
  28.  
  29. void MainWindow::on_txtSearch_textChanged(QString )
  30. {
  31.     QString sSearch = ui->txtSearch->text(); // txtSearch is a QLineEdit 
  32.      ui->lstNamesControl->clear();
  33.     for(int iIndex = 0; iIndex < lst_ListItems.count(); ++iIndex)
  34.     {
  36.         pItem->setText(lst_ListItems.at(iIndex));
  37.         if(pItem->text().contains(sSearch, Qt::CaseInsensitive))
  38.             ui->lstNamesControl->addItem(pItem);
  39.     }
  40. }
