Modifying QML properties from C++

[Erlend E. Aasland]

I'm trying to modify the "text" property of some QML Text widgets from C++. The QML part looks kinda like this:

Text {
id: my_id
objectName: "my_id"
text: "N/A"
}

And the C++ part like this:
QObject *obj = root_object->findChild<QObject *>("my_id");
if (obj)
obj->setProperty("text", "new text");

I have no problem finding the child by objectName, but setProperty() fails to update the GUI. I suspect this has something to do with dynamic properties, and I bet there is a very simple solution to this. I'd be very glad if someone could enlighten me about what I'm doing wrong here.

BTW: If it's not possible to do this via C++, how can I access stuff via objectName from QML?

Hi! This should actually work. Can you please provide a minimal example with a single qml-file and a single main.cpp, so we can try to find out what the problem is?

Solved it: Had to use QQmlProperty text(obj, "text").write(new_text);
