QColumnView的使用

#include <QtGui>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    QMainWindow win;
    QColumnView *cview = new QColumnView;
    win.setCentralWidget(cview);

    /* Create the data model */
    QStandardItemModel model;

    for (int groupnum = 0; groupnum < 3 ; ++groupnum)
    {
        /* Create the phone groups as QStandardItems */
        QStandardItem *group = new QStandardItem(QString("Group %1").arg(groupnum));

        /* Append to each group 5 person as children */
        for (int personnum = 0; personnum < 5 ; ++personnum)
        {
            QStandardItem *child = new QStandardItem(QString("Person %1 (group %2)").arg(personnum).arg(groupnum));
            /* the appendRow function appends the child as new row */
            group->appendRow(child);
        }
        /* append group as new row to the model. model takes the ownership of the item */
        model.appendRow(group);
    }

    cview->setModel(&model);

    win.show();
    return app.exec();
}
