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.

@FumbleFingers said in Find and highlight a specific row in tableview:

It may not be everyone's favourite coding style, but it works for me.

Umm, you assign to idx in the middle of passing a parameter, and then use it afterwards!? :)

Hi, I faced the same problem, failed to load OPC UA plugin:
qt.opcua: Failed to load OPC UA plugin: "open62541"
qt.opcua: Available plugins: QList("open62541")
Could not create client

I solved by putting libcrypto-3-x64.dll in the output build directory. Open62541_backend.dll depends on libcrypto-3-x64.dll, you can check it by using Dependency Walker tool.

My env: Qt 6.6.0, MSVC2019 64bit.

@lartimus could you find any solution for this situation. I have same warnings for d3d11 also. I can't find any solution for this.

I have installed emsdk using

./emsdk install sdk-fastcomp-1.38.27-64bit ./emsdk activate sdk-fastcomp-1.38.27-64bit

bcz installation fails(Error : No such tool/sdk) with

./emsdk install sdk-1.38.16-64bit

and using online installer as well as offline static build
am getting same error for simple Qt Application build

so what is cuase here and i am using Ubuntu 18.04 VM
kindly let me root cause

For example: QCameraImageProcessing

No problem :)

Since you have it working now, please update the thread title prepending [solved] so other forum users may know that a solution has been found :)

Also, when encountering answer(s) that helped you, please consider up-voting them so that other users may find them more easily.

Happy coding !

Hi,

most of the Qt3D-demos are now working also for me,
just some of them have still errors (=application remains completely black):
1) assimp* //
2) deferred-renderer*
3) multiviewport
4) tesselation-models
5) and I see no difference with and without referencing "test_scene.dae"
      with SceneLoader in the project "playgorund-qml".
      What should I expect to see when I reference "test_scene.dae"?
      ( this is what I see: http://privet.bplaced.net/temp/playground-qml.png )

Do you experience the same behavior?

@SGaist
Thanks! I didn't see any bug reports that looked relevant. I'll file one.

@cybercatalyst said:

@sirop

Yes, but I think feature-wise QtWebServer is already more superior than QtWebApp.

Agree. Therefore I watch your repo from now on. :)

@mcosta thanks. i am using a custom info.plist and that is where i set the UILaunchImageMinimumOSVersion as described in http://doc.qt.io/qt-5/platform-notes-ios.html#launch-images

i just can't get it to work, so i am wondering if anyone else has got this working ?

also looked at the weather app example but that one is done manually in xcode after the xcode project file has been created ( https://qt.gitorious.org/qt-labs/weather-app/source/e2c92d9d1e978aacc6a541e175dbd9931ca3470f:ios/readme.txt ) i guess this is a fallback option.. but i am still hopeful that http://doc.qt.io/qt-5/platform-notes-ios.html#launch-images can be used.

Thanks!

It seems to be an old unresolved bug. I posted on:
https://bugreports.qt.io/browse/QTBUG-34127
