QObject dynamic properties and QML binding

Say I have this:

Code:

---

Rectangle {
  width: object.dynamicProperty
}

---

If dynamicProperty changes no dynamicPropertyChanged signal will be issued, hence width won't change. Is it possible to somehow simulate a NOTIFY signal for a dynamic QObject property?

what kind of object is "object" c++, custom qml,... ?

Are you sure, as in, you've conclusively demonstrated this in your working code? From the docs:

Quote:

---

The property value is automatically kept up to date if the other properties or data values change.

---

The value is kept updated only if a notification signal is sent by the C++ object containing the property.

@ugluk: Why do you need a dynamic property to be reflected in QML? Can't you use a real property instead?

No, I can't. I thought that there perhaps exists a way to send a dynamic signal. I think that dynamic properties would fit well with a scripting language (which is also dynamic).

"object" is a C++ object (inheriting QObject).

Why can't you use real properties?
