How to present data in a list

[helloworld]

Something like...

mainwindow.h:

#include <QtGui/QMainWindow>
 
class QLineEdit;
class QListWidget;
 
class MainWindow : public QMainWindow
{
    Q_OBJECT
 
public:
    MainWindow(QWidget *parent = 0);
    ~MainWindow();
 
protected slots:
    void addItemToList();
 
private:
    QLineEdit   *m_edit;
    QListWidget *m_list;
};

#include <QtGui/QMainWindow>

class QLineEdit;
class QListWidget;

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = 0);
    ~MainWindow();

protected slots:
    void addItemToList();

private:
    QLineEdit   *m_edit;
    QListWidget *m_list;
};

To copy to clipboard, switch view to plain text mode 

mainwindow.cpp:

#include <QListWidget>
#include <QLineEdit>
#include <QVBoxLayout>
#include "mainwindow.h"
 
MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent),
      m_edit(new QLineEdit),
      m_list(new QListWidget)
{
    QWidget *widget = new QWidget;
    QVBoxLayout *layout = new QVBoxLayout;
    layout->addWidget(m_list);
    layout->addWidget(m_edit);
    widget->setLayout(layout);
    setCentralWidget(widget);
 
    QObject::connect(m_edit, SIGNAL(returnPressed()),
                     this, SLOT(addItemToList()));
}
 
MainWindow::~MainWindow()
{
}
 
void MainWindow::addItemToList()
{
    m_list->addItem(m_edit->text());
}

#include <QListWidget>
#include <QLineEdit>
#include <QVBoxLayout>
#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent),
      m_edit(new QLineEdit),
      m_list(new QListWidget)
{
    QWidget *widget = new QWidget;
    QVBoxLayout *layout = new QVBoxLayout;
    layout->addWidget(m_list);
    layout->addWidget(m_edit);
    widget->setLayout(layout);
    setCentralWidget(widget);

    QObject::connect(m_edit, SIGNAL(returnPressed()),
                     this, SLOT(addItemToList()));
}

MainWindow::~MainWindow()
{
}

void MainWindow::addItemToList()
{
    m_list->addItem(m_edit->text());
}
