问题 I was wondering if anyone has worked on Qt Remote File Browser. From my understanding, I have two options; Use QFileDilaog with a custom proxy model when it comes to remote files.

In both cases, the process of getting remote file/directory list can be accomplished using QNetworkAccess manager. Has anyone

问题 I am performing a https get operation with QNetworkAccessManager. I am hitting SSLErrors at runtime. After researching for a while I was able to get my program running after installing OpenSSL. I required two dlls: libeay32.dll and ssleay32.dll. Is it to say that I cannot perform https "get" operation using QNetworkAccessManager without OpenSSL ?? Doesn't Qt support native https support using QNetworkAccessManager. Thanks, De Costo. 回答1: Had to install the following dll's found at the

问题 Have an application where I have QOBJects which all contain an QNetworkAccessManager. I am aware of that it's suggested to only have on per application but since I'm making a lot more that 6 calls at the same time, I needed to have it like this. So, this is how I start the threads. FileUploader *fileUploader = new FileUploader(_fileList); QThread *fileUploaderThread = new QThread(); fileUploader->moveToThread(fileUploaderThread); // uploader > model connect(fileUploader, SIGNAL

问题 I have my first Qt application in development. It's a desktop client for site messaging. Qt documentation says that i need to have only one instance of QNetworkAccessManager accross application. But i also read that using of singletons with Qt isn't a good idea. How i can make one instance of QNetworkAccessManager across app? Another question is how to properly connect slots while i call ApiHandler functions from other classes? For example i have ExampleApi class which uses functions of

That request reports failure. I then send a GET request for a file that should be valid. That request never emits a finished signal or error. Qt 4.7.4 Please help! This is

Qt Jambi: Accessing the content of QNetworkReply

由 China☆狼群 提交于 2019-12-06 16:01:46
I'm having trouble accessing the content of QNetworkReply objects. Content appears to be empty or zero. According to the docs (translating from c++ to java) I think I've got this set up correctly, but to no avail. Additionally an "Unknown error" is being reported. Any ideas much appreciated.
