    You do not give us the details of what exactly/happens.

    Even before copying dll’s it crashes windows on run or debug.

    If your program crashes, nothing to do with deployment, sort that out first. If you can get it to crash from a debugger show the stack trace.

    Btw, does it go wrong if you replace the QWebEngineView with something else, like a plain widget/label?

    Hi,

    A model does not have any visual presence. There might be views on top of it though.

    What exactly is your architecture ?

    Please try with Qt Creator 16. If the performance is still bad, please do open a bug report at https://bugreports.qt.io/secure/CreateIssue.jspa?pid=10512

    When I selected such a Device:
    android9.png
    , the program almost started.
    There was nothing in the Problems window.
    But in the Output window there were warnings and errors:
    output1.png
    output2.png
    .
    And the program still did not start:

    @Aman55
    What error? The messages you show in your first post when debugging? There is no error. For me they did not appear when I used Qt5 under Ubuntu 22.04 but all appear when I moved to Qt6 under Ubuntu 24.04. Very irritating. I raised the issue at https://askubuntu.com/questions/1526550/ubuntu-24-04-gdb-gnu-debugaltlink-missing-file-messages. No resolution, it's a change in gdb behaviour.

    Hi all. So, I want to use QVTKRenderWindowInteractor for displaying some 3D data and, in the same app, I want to have QWebEngineView to render interactive bokeh plots.
    It seems not possible, however. Both widgets work ok when separated, but QWebEngineView is not rendered once I put both to the same app.
    I tried:

    First creating QWebEngineView and then QVTKRenderWindowInteractor and vice versa. I tried to use the following lines in case the problem is that both are trying to use GPU. os.environ["QTWEBENGINE_DISABLE_GPU"] = "1" os.environ["QTWEBENGINE_CHROMIUM_FLAGS"] = "--disable-gpu --disable-software-rasterizer"

    I have seen this workaround - https://discourse.vtk.org/t/cannot-use-qvtkrenderwindowinteractor-and-qwebengineview-together-in-one-application/5059. But I would like to find some easier one :(

    Questions:

    Is the problem that they are fighting for GPU or rather for some other resource? Can there be some other workaround instead of embedding code? Can I use something else other than QWebEngineView that would not create conflict but would allow me to create interactive plots? I have thought about rendering png and just setting it as image to some simpler widgets, but sadly it is not possible as I really need user to have possibility to interactively navigate in the plot.

    @AnneRanch seriously? That's five years ago, four years before you joined.

    Nor is it relevant to your question.
