How to access QQmlListProperty<T> size function from Qml?

Question

When you implement a QQmlListProperty and defined the count and at functions you can then call this from the Qml side. For the at function I have already understand that I can use the following sintax:

collection.items[0]

However, I couldn't still understand how do I call the size/length/count function. Does any know?

Answer 1

I have just found the answer:

collection.length

[EDIT]

The answer is in Qt Documentation:
