    Hello, I have a question regarding a difference in the behaviour of QWidget::raise () between Windows / MacOS. On MacOS, calling the method gives focus to the widget, but on Windows this is not the case.

    It can be tested by periodically calling raise () on a QWidget, and trying to write on a text editor while the Qt application is running. On Windows one is able to continue writing indefinitely, whereas on MacOS focus is taken out of the text editor and given to the QWidget.

    Is this a known / accepted difference of behaviour across the two OS? Is it a bug?

    Thanks in advance.

    Hello, I've started creating mobile apps for android, via QtCreator's inbuilt SDK manager.

    It's a CMake Qt Widgets application that has not been modified in any meaningful way. I wanted to test out the emulator, just in case it doesn't work.

    It didn't.

    In particular, the error message is:

    BUILD SUCCESSFUL in 10s 33 actionable tasks: 33 up-to-date Android package built successfully in 11.260 ms. -- File: U:/repos/StudyGo2/build/Android_Qt_6_9_0_Clang_arm64_v8a-Debug/android-build-StudyGo2//build/outputs/apk/debug/android-build-StudyGo2-debug.apk 04:15:51: The process "C:\Qt\6.9.0\mingw_64\bin\androiddeployqt.exe" exited normally. 04:16:21: The deployment AVD "GalaxyNexus" cannot be started. 04:16:21: Error while building/deploying project StudyGo2 (kit: Android Qt 6.9.0 Clang arm64-v8a) 04:16:21: When executing step "Deploy to Android device" 04:16:21: Elapsed time: 00:42.

    AVD config:

    Device Name: Galaxy Nexus Device Type: Emulator for "" Serial Number: Unknown CPU architecture: arm64-v8a OS version: Unknown Android Version. API Level: 36 (SDK 36) Android target flavour: Unknown SD card size: Unknown Skin Type: Unknown OpenGL status: Unknown

    Projects mode config:
    Build and Run for Android Qt 6.9.0 Clang arm64-v8a.
    Everything here is set to the default configurations. Since the app compiled correctly, and the deployment fails before actually doing the deployment, I don't think this is the problem.

    I have HyperV turned on. I've also tried restarting in case it's an issue with the environment variables. I have not tried using ADB to deploy to a physical device, because I do not have an android device at the moment.

    I think a possible reason is SD card size being Unknown despite having selected the default option of 512MiB when creating the configuration. However, I don't know if this is normal, nor how to test it.

    Since you wrote that the example is building successfully, what about copying it and the gradually replace its content with the one from your project ?

    Hi and welcome to devnet,

    The first thing to do would be to update Qt. 5.7.1 has reached end of life a long time ago. Also, that outdated WebKit version is likely too old to support the modern JavaScript stuff.

    Hi,

    Did you also try with a less recent version of Qt such as 6.8 ?

    Aha! found what I was looking for on a old blog post!

    Qt OPC UA will be available directly from the Qt installer for those holding a Qt for Automation license. [...] Users of one of the Open Source licenses will need to compile Qt OPC UA themselves. See here for a list of build recipes.

    this really should be clearly stated on documentation...

    Hi and welcome to devnet,

    How are you setting up your label ?

    On a side note, I would recommend you take the time to re-evaluate your architecture. Your chain of dialogs is currently pretty brittle.
    There are other ways to switch from one widget to another that does not involve creating a new widget every time.
    Check for example QStackedWidget.
    You might want to also consider QMainWindow which provides a status bar.
    Depending on the error you might want to consider a QMessageBox using the appropriate level of urgency to show the message.
