QML functions can be called from C++ and vice-versa.

All QML functions are EXPOSED to the meta-object SYSTEM and can be called USING QMetaObject::invokeMethod().

Here is a C++ application that uses this to call a QML function:

// MyItem.qml

import QtQuick 1.0

ITEM {

function mysql Function(msg) {

console.log("GOT message:", msg)

return "some return value"

}

}

// main.cpp

QDeclarativeEngine engine;

QDeclarativeComponent component(&engine, "MyItem.qml");

QObject *object = component.creator();

QVariant returned Value;

QVariant msg = "Hello from C++";

QMetaObject::invokeMethod(object, "mysql Function",

Q_RETURN_ARG(QVariant, returned Value),

Q_ARG(QVariant, msg));

qDebug() << "QML function returned:" << returnedValue.toString();

delete object;
