zhengtianzuo系列-QmlTableView使用QtQuick的MVC模式新建c++类继承于QAbstractTableModel, 并实现几个重要方法: CPP中: ``` class QmlTableViewModel : public QAbstractTableModel { Q_OBJECT public: explicit QmlTableViewModel(); int rowCount(const QModelIndex & parent = QModelIndex()) const Q_DECL_OVERRIDE; int columnCount(const QModelIndex &parent = QModelIndex()) const Q_DECL_OVERRIDE; QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const Q_DECL_OVERRIDE; QHash<int, QByteArray> roleNames() const Q_DECL_OVERRIDE; Q_INVOKABLE void Add(QString one, QString two, QString three); Q_INVOKABLE void Set(int row, int column, QString text); Q_INVOKABLE void Del(); Q_INVOKABLE void Refresh(); private: QVector<QVector<QString>> m_aryData; }; ``` 注册c++类: ``` QmlTableViewModel model; engine.rootContext()->setContextProperty("theModel", &model); ``` rowCount 获取总行数 columnCount 获取总列数 data 获取当前数据 roleNames mvc别名 Qml中: ``` QmlTableView{ id: qmlTableView height: frmWindow.height - 40 width: parent.width tableView.itemDelegate:Rectangle { TextField{ id: textField height: 25 text: styleData.value selectByMouse: true onEditingFinished: { theModel.Set(styleData.row, styleData.column, textField.text); } visible: (styleData.column !== 0) } Image{ id: image height: 25 width: 25 source: "qrc:/Face.png" visible: (styleData.column === 0) } } tableView.rowDelegate: Rectangle { height: 25 } } ```  需要完整代码请访问 QtQuickExamples |
