　　这一节我们来介绍QListWidget的用法，QListWidget、QTreeWidget和QTableWidget都是将模型和视图结合起来，QListWidget将其显示效果与MFC的ListCtrl控件是一样一样的，下面是其简单的使用。就一个main.cpp

#include <QtGui/QApplication>#include <QWidget>#include <QLabel>#include <QListWidget>#include <QHBoxLayout>#include <QIcon>int main(int argc, char *argv[]){    QApplication a(argc, argv);    QLabel *label = new QLabel;    label->setFixedWidth(100);    QListWidget *listWidget = new QListWidget;    listWidget->addItem(new QListWidgetItem(QIcon(QObject::tr("images/china.png")), QObject::tr("China")));    listWidget->addItem(new QListWidgetItem(QIcon(QObject::tr("images/hk.png")), QObject::tr("Hong Kong")));    listWidget->addItem(new QListWidgetItem(QIcon(QObject::tr("images/macau.png")), QObject::tr("Macau")));        QHBoxLayout *mainlayout = new QHBoxLayout;    mainlayout->addWidget(listWidget);    mainlayout->addWidget(label);    QObject::connect(listWidget, SIGNAL(currentTextChanged(QString)), label, SLOT(setText(QString)));        QWidget *widget = new QWidget;    widget->setLayout(mainlayout);    widget->setWindowTitle(QObject::tr("QListWidget Demo"));    widget->show();    return a.exec();}

　　运行界面如下：
