QtWebEngine

@SGaist Thanks, I'll give it a try.

@alvazz You still haven't said what and how you're measuring. Creating a web engine view is a heavy task. It spins up entire chromium and javascript engines. It also changes rendering backend from software based widgets to hardware accelerated chromium surface. If you're planning on switching to and from it a lot then you should create it once and just show/hide, not recreate every time you want to show new page, because yes, that's going to be slow like closing and re-opening a browser.

@JW16 I think you should add wv->close() before exiting, just in case that allows it to clean up better. Also does it still crash if you compile for release? If it only happens in debug you may end up chasing your tail. If I instead delete the app prior to calling exit(), there is no crash. Is that not a viable workaround if you find it is the only solution?

Hello everyone, i will share some experience to compile qtmodule at the arm64 platform. The configure command is ./configure -prefix 'installed position' -opensource -confirm-license -nomake examples -nomake tests -nomake tools -make libs -shared -fontconfig -pkg-config -opengl es2 -egl -xcb -xkbcommon -release and when you should ensure all library was installed by config.summy or check config.log. Thanks.

So if anyone finds the same issue, the workaround can be found here: https://github.com/probonopd/linuxdeployqt/issues/554 I just put the line: qputenv("QTWEBENGINE_CHROMIUM_FLAGS", "--disable-gpu --no-sandbox"); And everything started to work.

@BlinCt said in Add to web open pdf and txt files: there are no settings for docx files? Most probably not. I don't think any existing browser can show Microsoft Office files without plug-ins (maybe Microsofts own browsers can).

After all, I configured everything wrong, disregard my code above, i have posted in this Topic the solution.

@JonB Hello thanks for your precision. Is there another way to make a c++ method communicate with a javascript code of an html page loaded in a qml file? If there is I didn't know about it. I have inserted the post in the QtWebEngine section specially. Anyway, It is true that questions asked in the right way are easier to interpret and solve. After seeing the proposed link I solved it as follows. QJsonDocument json(recordsArray); json.setArray(recordsArray); QJSEngine engine; QJSValue resDatiSqlJsonValue; if (json.isObject()) { resDatiSqlJsonValue = engine.toScriptValue(json.object()); } else if (json.isArray()) { resDatiSqlJsonValue = engine.toScriptValue(json.array()); } else { resDatiSqlJsonValue = engine.newErrorObject( QJSValue::TypeError, "JSON was neither an object nor array. Strange, right?" ); } emit testJsonReturn(resDatiSqlJsonValue); Thanks

@JoeCFD Where is it located in the relative /QT folder? /... like 5.12.5 , dist, Docs, Examples

@JonB lucky we))) but not enough///// Coz I still have enough problems. I should have had working support for compiling QPDF* classes. But because it was built into the QWebEngine module, which now only supports x64, so now I've failed... completely... Main problem of this topic is revealed, but mine problems are still with me...

@nodeepshit We are having a similar issue: https://bugreports.qt.io/browse/QTBUG-99428

Hi, WARNING: I am not a lawyer. I would say you are correct. You should bring this to the Qt Company. This a user forum.

@Coder91 Hi, Look at signals of QWebEngineDownloadItem and Managing Downloads at the end of this page : Simple Browser
