(Py)Qt：图像下载问题
伙计们
我想在 QTextEdit 中显示一些带有标题的图像。我有一本带有标题和相应网址的字典。问题是，当我使用 QNetworkAccessManager 发布请求并等待信号完成（QNetworkReply*） 时，我仅得到带有图像的回复。如何确定该图像所请求的相应标题？
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_record(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');
有没有针对这个问题的设计模式？我将不胜感激任何想法
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_record(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

假设使用最新的 Qt 版本，
QNetworkReply::request()< /a> 将为您提供一个指向触发此回复的QNetworkRequest的指针。因此，您可以使用
QNetworkRequest::url()< 访问所需的信息/代码>。Assuming a recent Qt version, the
QNetworkReply::request()will give you a pointer to theQNetworkRequestthat triggered this reply.So you can access the information you're after with
QNetworkRequest::url().
