Making a QPROPERTY read only in QT

Question

I have a property which does some calculation over the variable, but I don't want the reflected variable to reflect the UI, so I just need to do some calculations but the final result shouldn't reflect the UI in the property.

Answer 1

Just don't add a write accessor, e.g.

class MyClass : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int myVar READ myVar NOTIFY myVarChanged) //No WRITE ...

public:
    int myVar() const;

signals:
    void myVarChanged(int myVar);

private:
    int m_myVar;
}
