enlighten me on the use of Q_PROPERTY!!

Hi,

Why should one use Q_PROPERTY? as in what advantage does it have over declaring the corresponding attributes and associated READ and WRITE functions as private/public??

Thanks

Properties can be written and read through QObject interface.
You can access the properties without knowing anything about the class in use.
Qt's Property System

It's not the fastest possible way to access data members of a class, the value of properties comes from genericity.

It's used for example by the Qt Designer to change widgets' settings.

Actually you will still need to write such methods. Q_PROPERTY just informs Qt about them.

Look at the Qt Designer --- it doesn't know anything about custom widgets, yet if you create a custom widget plugin, you will be able to change that widgets' properties. How would you implement this without Q_PROPERTY?
