I have a problem with subclassing QNetworkReply.
When I make a Subclass and call isFinished i get always false as result, and have no way to change it manually since this method is only virtual in QNetworkReplyPrivate. But as the name says, this class doesnt belong to the public API so i can’t change it at that location.
So what can I do to get this method working correctly?
That was not an answer to my question :). After a quick review the whole implementation leads me to believe the QNetworkReply isn’t there to be subclassed (by non-qnetwork code that is). If you really need to subclass this thing, you should have it depend on on the non-public API, I’m afraid.
That is why I wanted to know why you are trying to subclass it — what are you trying to achieve that you need this subclass for?
When you’re done with your work, you must emit signal finished().
You cannot do that in the constructor of your QNetworkReply subclass, because at that time the signal/slot connections in your client code were not setup!
Some more info on this in the Qt mailing list [lists.trolltech.com]
i am emitting finished. That is noth the problem. I am talking about QNetworkReply::isFinished() not about the SIGNAL QNetworkReply::finished() .
I found no line in the Qt source where this Signal is connected internally. Also connecting it internally wouldnt solve my problem, since in QNetworkReplyPrivate the method isFinished always returns false. I cant change that private class to have a late binding on that function.
I overlooked that. That’s a bug, indeed. It’s already addressed and fixed by Nokia, see QTBUG-11737 [bugreports.qt.nokia.com], although it will be public not until Qt 4.8.0.
