如何将C++模型公开给QML

class MyModel : public QObject {
    Q_OBJECT
    Q_PROPERTY(QString name READ name WRITE setName NOTIFY nameChanged)

public:
    QString name() const {
        return m_name;
    }

    void setName(const QString &name) {
        if (m_name != name) {
            m_name = name;
            emit nameChanged();
        }
    }

signals:
    void nameChanged();

private:
    QString m_name;
};

qmlRegisterType<MyModel>("com.example.mymodel", 1, 0, "MyModel");

import QtQuick 2.12
import com.example.mymodel 1.0

Item {
    MyModel {
        id: myModel
        name: "John Doe"
    }

    Text {
        text: myModel.name
    }
}

class MyModel : public QObject {
    Q_OBJECT
    Q_PROPERTY(QString name READ name WRITE setName NOTIFY nameChanged)

public slots:
    void handleButtonClicked() {
        // Handle button click event
    }

private:
    QString m_name;
};

import QtQuick 2.12
import com.example.mymodel 1.0

Item {
    MyModel {
        id: myModel
        name: "John Doe"
    }

    Button {
        text: "Click me"
        onClicked: myModel.handleButtonClicked()
    }
}
