QtWebEngine

@jsulm no for sure ..... i try only the default installation with default project example before try to use open62541 on these new SO .... for check if all work. Pherhaps qtcreator 14 (desktop devlopment) is different from previous install on LMDE6 ... not understand how can change it .... seems compiler default is ninja .... not understand how to obligate system to use gcc .... there are not "set as default" options ...

@7erg Does it help to reduce the number of parallel build processes?

it's ok ,configure add " -qt-libjpeg -qt-libpng " parameters

it's resolve on debian 11,the problem repeat on debian 12

Just in case you stumble onto this issue, the Qt Documentation now contains instructions cf https://doc.qt.io/qt-6/qtwebengine-deploying.html#macos-specific-deployment-steps Here is the content of the QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/Resources/QtWebEngineProcess.entitlements for reference, for my macos install, v 6.5.2 $ cat /Users/julien/Qt/6.5.2/macos/lib/QtWebEngineCore.framework/Versions/A/Helpers/QtWebEngineProcess.app/Contents/Resources/QtWebEngineProcess.entitlements <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.cs.allow-unsigned-executable-memory</key> <true/> <key>com.apple.security.cs.disable-library-validation</key> <true/> <key>com.apple.security.cs.allow-jit</key> <true/> <key>com.apple.security.cs.disable-executable-page-protection</key> <true/> </dict> </plist>

@lille said in buildroot for qt 5.15.2 compile!: Be sure must install libharfbuzz-dev package in host developer? No. If you're cross compiling then all needed libraries/headers have to be in your sysroot.

@emircanacardev said in QtWebEngine and JS Integration: WebEngineScriptCollection is not support the qt 5.x i think. Am i right. Qt 5.15 didn't have WebEngineScriptCollection, but it still has a list of user scripts: https://doc.qt.io/qt-5/qml-qtwebengine-webengineview.html#userScripts-prop // script.js document.body.style.background = "#00aaaa" // *.qml in Qt 5.15 WebEngineView { id: webView anchors.fill: parent url: "chrome://gpu" WebEngineScript { id: script sourceUrl: Qt.resolvedUrl("scripts.js") } Component.onCompleted: webView.userScripts.push(script) } // *.qml in Qt 6.7 WebEngineView { id: webView anchors.fill: parent url: "chrome://gpu" Component.onCompleted: { let script = WebEngine.script() script.sourceUrl = Qt.resolvedUrl("scripts.js") webView.userScripts.insert(script) } }

when I resize the qwebengineview,the errors came out.I guess maybe it was caused by the chorum ui threads. cause When I resized the qwebengineview very quickly then the program crashed.heres the detail information. by the way.are there any ways that could resize the qwebengineview normally? code_text [opengl\qopenglframebufferobject.cpp line 570] OpenGL Error: 1281 QOpenGLFramebufferObject: Framebuffer incomplete attachment.

and if I set the source file whit the setHtml() function. it is hard to get the real height and width if the source was made by the txt.

Do you have a solution for that problem? I need.

I dont get errors when i use gold linker but website’s dont load , i get blank screen.

hi！did you solve the problem, i met the same problem.

It's not related to Debug or Release. The error is caused by line endings. The parser expects unix instead of dos line endings.

Hi, You can build the latest Qt 5.15 for your project and if it works better. If so backport the changes.

Hi, You should move to PySide6. Support for OpenSSL 3 started with Qt 6. Even if the support is back-ported to 5.15, you would need to build PySide2 yourself with the corresponding version of Qt 5.
