QListWidget的簡單用法

　　這一節我們來介紹QListWidget的用法，QListWidget、QTreeWidget和QTableWidget都是將模型和視圖結合起來，QListWidget將其顯示效果與MFC的ListCtrl控件是一樣一樣的，下面是其簡單的使用。就一個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();
}

　　運行界面如下：
