Dynamic Q_PROPERTY Read / Write function ?

[MHermann]

Hi!

I have created some dynamic properties in my C++ class.
Is it possible to read the value of such a dynamic property from qml?
In qml I get noticed if the dynamic properties change, because of the onPropertyChanged signal.
But I want to read the value of a dynamic property once when the qml componentd was created (Component.onCompleted).
Has anyone an idea how I can do this?

Kind regards,
MHermann

Pretty sure that will show you what you need.

You can also jump straight into code and start tinkering - it's an example application. Just go to the Qt Creator welcome screen, examples and search "Writing QML Extensions with C++"

@6thC: Thanks for the hint.

I solved my problem by calling a C++ function which was made available by Q_INVOKABLE. In this function I am fetching and returning the requested data to the qml.
