ClassB, you are using it in a property.

By the way, why not use QObjectList and a Q_INVOKABLE method ? Might be more straightforward.

More information on how to integrate CPP with QML here.

I would have preferred a quicker way using Q_PROPERTY, but I think the only way is what you've suggested to me.
Thanks so much

I see. Thanks @raven-worx @SGaist!

When one declares a property with MEMBER feature the QMetaProperty is reporting that the property is writable.

This is quite strange indeed.

I solve my problem removing the MEMBER declaration!

This is certainly a possibility. Still I'm glad it's working for you,

Any other idea why the WRITE function is not called at the widget’s pseudo state change when the stylesheet has different qproperty values defined for the states?

Hi,

Q_INVOKABLE is used to make functions accessible throughout Qt meta object system. Q_PROPERTY is much more complex and offers additional features

You don't have to mix anything.
What you use in your enum are hexadecimal values not binary.
That means (left side hex, right side binary): 0x0 == 0, 0x1 == 1, 0x10 == 10000, 0x100 == 100000000!
I guess what you actually want is what Chris Kawa said: 0x01 == 1, 0x02 == 10, 0x04 == 100, 0x08 == 1000, 0x10 == 10000

After scouring the web, it appears that the only way to do this is the very complex technique of subclassing the widget. It's easier to just put another button on it, but then I had the problem where I couldn't pass a hover event to the QPushButton underneath it. This lead me to learn the technique on StackOverflow of building an eventFilter.

Thanks! I fix the problem. All works fine, but I have a Rectangle over that hide the window background and that was the problem.
