QtWebEngine

@Will-Stokes Welcome, and thanks again for sharing your findings! @SGaist Nothing needs fixing here. The OP's entitlements weren't enough; Will found the correct entitlements that macdeployqt uses.

i found the problem since direct3d11 support with qt6.51。the direct3d11 make render good on some computer。but on some computer will cause the problem。

I've submitted a Qt bug report for this: https://bugreports.qt.io/browse/QTBUG-119614 "SSL initialization is around 10 to 100 times slower in Qt 6"

Hi, You should contact the PyQt folks on their forum as they will have better insight for that question.

Hi guys Now, I'm 100% convinced that this issue was caused by video codecs H264 not supported by default in QtWebEngine. Thanks for your support.

@nikelsq This is user forum. For change requests you should go to Qt bugtracker (https://bugreports.qt.io/secure/Dashboard.jspa) or Qt developers mailing list (https://lists.qt-project.org/listinfo/development).

@SGaist I am using this layer for that https://code.qt.io/cgit/yocto/meta-qt6.git/tree/recipes-qt/qt6 .please help me to downgrade to the 50-based branch if possible

@JonB Thanks for looking. Yes, I need to convert HTML to PDF. Agree, possibilities are many and this is not a clear question with a straight answer. I just posted in case someone had hit something like this before or someone in the know how of Qt WebEngine might have some pointers for me. I had tried printing the HTML to PDF using QPrinter and it was not satisfactory even with a basic html. I was reading QtWebEngine and internally Chromium does not use QNetworkAccessManager (like Qt WebKit). It has its own implementation of network and this is what I feel is failing somewhere on Linux. So eventually if I have to figure out, I probably will have to debug inside Chromium to see what is happening. PS: For now there is a solution with Qt WebKit and so not super urgent but eventually I might have to figure out the Qt WebEngine solution.

@Alexuds79 In case anyone finds the same problem in the future, using QtWebView (https://doc.qt.io/qt-5.15/qtwebview-index.html) instead of QtWebEngineView seems to solve the problem on MacOS. However, on Windows (again with the final application built), it seems that QtWebEngineView works perfectly but QtWebView does not (the WebView QML component is not shown). Fortunately, with simple logic you can use one or the other depending on the platform.

@Wycer said in No gn found for cross-compilation: @SamiV123 I do need, main module of my project. I googled a lot and eventually found that link too, however I am not sure what to do next. I tried following their install process but still got the error, I tried installing using apt and also didn't work. If you can guilde me a little more that would be great! And thanks a lot for your time and effort :) Sorry, all I can offer is try following the chromium build instructions, if you can get your env to a point where you can build the chromium source then it should hopefully work for Qt as well. https://www.chromium.org/developers/how-tos/get-the-code/

@arshadm25 i have resolved this issue by using the setTransferTimeout method of QNetworkAccessManager.

@Axel-Spoerl I have the same problem, and my return is r@r-virtual-machine:~/code/qt-everywhere-src-5.15.2/build$ find /usr -name khrplatform.h /usr/include/KHR/khrplatform.h

@Volker75 Yes, my recollection is you do have to attach a slot to loadFinished() for printing to work, doubtless previewing too. Seems reasonable to me.
