    Note that we provide QtWebKit TP5 binaries compatible with official Qt 5.8.0 MinGW build: https://github.com/annulen/webkit/releases/tag/qtwebkit-tp5

    Thx for the heads up.

    Are the 5.8/Webkit binaries also available for MacOS-clang64 environments?

      @PSI_lbc Yeah, see the same link. Also there are binaries for 64-bit Linux and VS 2015 (both 32-bit and 64-bit)

        Thank you for all your work. its a huge task for a beginner to build webkit so your project
        is very welcome.

          @mrjj As for these binary packages, credits go to CI infrastructure of The Qt Company, and personally to Simon Hausmann who helped a lot with integration of new QtWebKit's build system into Coin.

          Also credits go to Vitaly Slobodin and other contributors of revived QtWebKit, who contributed lots of patches enhancing Windows and macOS support. Without them, it could happen that only Linux would be supported.

            Thx for the reply. I made a mistake downloading the open source install.
            I am now using: qt-unified-windows-x86-2.0.5-online.exe...and have a current Commercial License for Application Development..all handheld and desktop environments are covered.

            I tried installing Qt5.7.1 for MinGW but there were no QtWebEngine libraries.
            I tried installing Qt5.7.1 for MSVC2015 and it had the QtWebEngine libraries, but no compiler.

            I am now re-installing 5.8, 5.7, and 5.6. Maybe one of those will have the libraries I need.

              Do you know if the 5.8/Webkit binaries support a mix of HTML and JavaScript on the same page?

              A real ancient version of WebKit I was using in Qt4.7.2 did not...which is what has prompted my attempted upgrade to Qt5x/WebEngine.

                Like written in the documentation I linked, QtWebEngine is not available with MinGW for the reason I have already given.

                As for Visual Studio, yes, it's up to you to install it. It has always been the case. Microsoft doesn't allow any third party to bundle its development suits.

                        I am still using the qt 5.5.1 mingw version, and using the default webview in that QT version. One BIG problem I met is memory leak seems still in qt 5.5.1 mingw version ...

                        Is the memory leak problem resolved in the qtwebkit-tp5-qt58-mingw530-x86.zip or qtwebkit-5.212.0_alpha2-qt59-mingw530-x86.zip from https://github.com/annulen/webkit/releases ?

                          I just tried qt-opensource-windows-x86-mingw530-5.8.0.exe and qtwebkit-tp5-qt58-mingw530-x86.zip, For one of my project works well with qt 5.5.1 mingw, now got below error when compiling, anything I should modify? Or anything missing?

                            What I am talking about the memory leak, is something as below:

                              Please try it out, IIRC I couldn't reproduce that issue.

                              Also, don't use QWebSettings::setObjectCacheCapacities(0,0,0), this indeed was causing leaks in the old versions, and WebKit isn't really tuned or even tested to operate with no cache at all.

                                Thanks for kind help, OK, I will try it out and report back.

                                BTW, is there any estimate target date for the beta or stable version? Thanks again.

                                Best regards, Jason

                                  Hello @Konstantin-Tokarev ,

                                  I tried with 5.8.0 and 5.9.2 and your corresponding release of QtWebKit, seems still the same symptom, the memory will keep increasing if I refresh the page repeatedly.

                                  BTW, the html pages I used are generated via vuejs, is that OK?

                                  Thanks a lot.

                                  Best regards, Jason

                                    It now says Qt Webengine component is only supported for MSVC 2017, took me a while to figure out.

                                      still think the components that are used in examples should be included by default or at least if nothing else warned that you wont be able to do some examples unless you have them (in the right places mind you, not tucked away in some weird documentation). It would also be nice if there is gonna be typing completion in qmake, cmake, etc., that it actually be contextual to the syntax of those items and not just spit out seemingly random tags most of which don't have anything to do with said files... even better, maybe include at least the headers that way you know for sure you are missing the library instead of ghostin' the whole kit'n'kaboodle.

                                      I'm truly glad you r/offmychess t finally, but please don't go too far, because you r/beyondvoxels and that implies that u r/donewithlife. Oh well time to git back to the lab, because azure sea here, I have a lot of work to do...
