A way to avoid boilerplate code for defining QObject properties in C++ (to be accessible from QML)?

Stefan Monov76

The Qt docs contain this example:

class Message : public QObject
{
    Q_OBJECT
    Q_PROPERTY(QString author READ author WRITE setAuthor NOTIFY authorChanged)
public:
    void setAuthor(const QString &a) {
        if (a != m_author) {
            m_author = a;
            emit authorChanged();
        }
    }
    QString author() const {
        return m_author;
    }
signals:
    void authorChanged();
private:
    QString m_author;
};

Is there a way to avoid writing all this boilerplate code just to define a QML-interoperable property? For example, since this code is calling the Q_PROPERTY macro anyway, can't this macro do the dirty work for me and define all the rest automatically?

Note: I've found a nice-looking set of macros here but it's not an official part of Qt, so I'm not sure if it's free of gotchas.

Hi,

Take a look at the MEMBER element of the Q_PROPERTY declaration here.

It likely does what you want.

Hope it helps
