(Py)Qt: problem with image downloading

guys

I want to display some images with their captions in QTextEdit. I have a dictionary with captions and corresponding URLs. The problem is when I post a request with QNetworkAccessManager and wait for a signal finished(QNetworkReply*), I get reply with image only. How can I determine a corresponding caption this image was requested for?

def _init_(self)
    manager = QNetworkAccessManager(self);
    self.connect(manager, SIGNAL("finished(QNetworkReply*)"), self.add_record)
    for record in dict:
        manager.get(QNetworkRequest(QUrl(status['caption'])))

def add_rec开发者_StackOverflow中文版ord(self, reply):
    img = QImage()
    img.loadFromData(reply.readAll())
    self.textEdit.textCursor().insertImage(img)
    #I don't know at this point for which caption
    #I've received this image
    #self.textEdit.append(record['text'] + '\n');

Are there any design patterns for this problem? I would appreciate any ideas

Assuming a recent Qt version, the QNetworkReply::request() will give you a pointer to the QNetworkRequest that triggered this reply.

So you can access the information you're after with QNetworkRequest::url().
