如何将QAbstractListModel分配给ListModel

// MyListModel.h
#include <QAbstractListModel>

class MyListModel : public QAbstractListModel
{
    Q_OBJECT
public:
    explicit MyListModel(QObject *parent = nullptr);

    // 重写rowCount()函数，返回模型中的行数
    int rowCount(const QModelIndex &parent = QModelIndex()) const override;

    // 重写data()函数，返回指定索引处的数据
    QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const override;

    // 重写roleNames()函数，返回角色名称
    QHash<int, QByteArray> roleNames() const override;

private:
    // 模型中的数据
    QList<QString> m_data;
};

// MyListModel.cpp
#include "MyListModel.h"

MyListModel::MyListModel(QObject *parent)
    : QAbstractListModel(parent)
{
    // 初始化模型中的数据
    m_data << "Item 1" << "Item 2" << "Item 3";
}

int MyListModel::rowCount(const QModelIndex &parent) const
{
    if (parent.isValid())
        return 0;

    return m_data.count();
}

QVariant MyListModel::data(const QModelIndex &index, int role) const
{
    if (!index.isValid())
        return QVariant();

    if (role == Qt::DisplayRole)
        return m_data[index.row()];

    return QVariant();
}

QHash<int, QByteArray> MyListModel::roleNames() const
{
    QHash<int, QByteArray> roles;
    roles[Qt::DisplayRole] = "displayRole";
    return roles;
}

// main.cpp
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include "MyListModel.h"

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    // 实例化自定义模型类的对象
    MyListModel myListModel;

    QQmlApplicationEngine engine;
    engine.rootContext()->setContextProperty("myListModel", &myListModel);
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    return app.exec();
}
