QTableView 结合QStandardItemModel 使用

mainwindow.h:

class MainWindow : public QMainWindow
{
Q_OBJECT

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

QStandardItemModel model;

};

mainwindow.cpp:

#include "mainwindow.h"
#include <QLayout>
#include <QTableView>
#include <QHeaderView>
#include <QDebug>


MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)

{
    this->setFixedSize(800,600);
    QWidget *widget=new QWidget(this);
    this->setCentralWidget(widget);
    QVBoxLayout *lay=new QVBoxLayout(this);

    QStringList headitems={"测试1","测试2","测试3","测试4"};
    QTableView *m_table=new QTableView(this);

    //自适应所有列，让它布满整个空间
    m_table->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);
    m_table->horizontalHeader()->setDefaultSectionSize(48);
    //m_table->setRowHeight(0,30);
    model.setHorizontalHeaderLabels(headitems);

    QList<QStandardItem*> list;
    for (int i = 0; i < 4; ++i) {
        QStandardItem *item = new QStandardItem("test"+QString("%0").arg(i));
        list<<item;
    }
    model.appendRow(list);
    m_table->setModel(&model);
    lay->addWidget(m_table);
    widget->setLayout(lay);

}

MainWindow::~MainWindow()
{

}
