Referencing id from string

[Paul Webster]

In my QML I have a grid of 64 of a custom component with id of a1 to h8. The custom component contains functions that I can call such as c2.clearPiece(). My C++ is returning the c2 to me as a string that I store into a var called from, however when I try to run the function from.clearPiece() I get "TypeError: Property 'clearPiece' of object c2 is not a function". Is there any way that I can use the data in the string to reference to the id? I have also set up objectName in the custom component. Is there any way that I can use a getChild() type function on the grid to get hold of the object?

@Paul-Webster I guess you can find a child with objectName, but not with id.

int main(int argc, char *argv[]) {
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    if (engine.rootObjects().isEmpty())
        return -1;

    // Assuming you have a QML root item
    QQuickItem* rootItem = qobject_cast<QQuickItem*>(engine.rootObjects().first());

    if (rootItem) {
        // Find child item by objectName
        QQuickItem* myObject = rootItem->findChild<QQuickItem*>("myObject");

        if (myObject) {
            // Do something with myObject
            qDebug() << "Found child object with objectName 'myObject'";
        } else {
            qDebug() << "Child object with objectName 'myObject' not found";
        }
    }

    return app.exec();
}

@JoeCFD So I would need to access it through C++, I can't do it from within the QML?

@Paul-Webster I think that I have it:

for(var i = 0; i < grid2.children.length; ++i)
if(grid2.children[i].objectName === from){
grid2.children[i].clearPiece()
}
