// Wait for request to complete 
bool QOrganizerItemRequestQueue::waitForRequestFinished(
        QOrganizerAbstractRequest* req, int msecs)
{

    // Create an event loop
    QEventLoop *loop = new QEventLoop(this);
    
    // If request state changes quit the loop
    QObject::connect(req, SIGNAL(stateChanged(QOrganizerAbstractRequest::State)), loop, SLOT(quit()));

    // Set a timeout for the request
    // NOTE: zero means wait forever
    if (msecs > 0)

    // Start the loop
    loop->exec();
    
    loop->disconnect();
