General and Desktop

@JonB Thank you for answering me. (a) I try to set my widget in a ScrollArea and use button to create or delete it repeatedly. The widget still shows ten times slower than using new project name. (b) I change the project name over and over again. Only a certain name cause this kind of delay. I know it doesn't make sense, but it really happened. I doubt that StyleSheet may cause this trouble. Should I breakdown my project more detail?

Grateful thanks for responses. Unfortunately the lengthy scavenger hunt I did resulted in no joy. Apologies for my obtuseness, but if I go File > New File or Project > Other Project > Empty qmake Project > choose and finish, can someone give me the minimum required in files/code/exact filenames to show a main form? (Creator is 6.0.2.)

Hi, Are you replacing the font for only these characters ? If so, you could create your own format that renders them at a sensible size.

@Lab7 That can happen from time to time. What were you trying to post ?

@thunder What's your question?

You should not change the way you write code based on a linter if the linter is wrong. However, widget should have a parent (maybe that happens when it is added to a layout). If you are using a linter, you shouldn't just turn it off entirely. So, the option that you have is to turn specific linting options off on a per line basis (https://stackoverflow.com/questions/37950439/inline-way-to-disable-clang-tidy-checks): Use NOLINT(...) on specific lines or NOLINTBEGIN(...)/NOLINTEND(...) on the whole section of code creating widgets and layouts. Make sure to just disable that one specific warning.

Hi, Using multiple views on top of the same model is one of the core feature of the model view paradigm. You have one single source of data and present it through different (or similar) means to the user.

It is a problem with the installer's binaries they were build on Ubunto with a different libc or libstdc++ library than on Raspberry. https://bugreports.qt.io/browse/QTBUG-137145 You can build it from the sources, then it works. Install required packages sudo apt install cmake libfontconfig1-dev libdbus-1-dev libfreetype6-dev libicu-dev libinput-dev libxkbcommon-dev libsqlite3-dev libssl-dev libpng-dev libjpeg-dev libglib2.0-dev libgles2-mesa-dev libgbm-dev libdrm-dev libvulkan-dev vulkan-tools Install wayland libs sudo apt install libwayland-dev libwayland-egl1-mesa libwayland-server0 Download and extract https://download.qt.io/official_releases/qt/6.8/6.8.3/submodules/qtbase-everywhere-src-6.8.3.tar.xz, tar -xf qtbase-everywhere-src-6.8.3.tar.xz Switch to the directory where the file is extracted, make a directory for the build inside, switch into the build directory cd /path/to/qtbase-extract, mkdir ./build, cd ./build Build cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/home/raspifm/Qt/6.8.3-aarch64 -DQT_FEATURE_opengles2=ON -DQT_FEATURE_opengles3=ON -DQT_FEATURE_kms=ON -DQT_AVOID_CMAKE_ARCHIVING_API=ON .. cmake --build . --parallel 4 Install cmake --install .

@l3u_ Could you mark this thread as solved, please?

That solved it. I'm not sure what happened, but something got messed up my build dir.

@AndyBrice I'm using the latest version of Qt and macOS/iOS 26. Nothing is compatible with Qt 6.9 and everything renders in the old version style.

@JonB, that's what I was looking for! Thanks.

Hi and welcome to devnet, Does it happen with only a single file or are they all affected ? It there somewhere a sample file that could be used to test this issue ? Which OS are you running your application on ?

That's how I understood the code.

@rcx11 it uses a similar approach to gRPC/QtRemoteObjects in that the files that are compiled are generated using calls to the generators via cmake. I checked Qt6.10.0 on windows 11 and indeed, until you configure the file cannot be found: The file that generated (for reference of others reading this thread): [image: 8bfbacc8-18a1-419d-9f48-7757554d7203.png] I'd recommend marking as resolved with @Paul-Colby 's response.

Hello, is there any update for this issue? I'm also facing the problem that the QEnums properties are not loaded by QtDesigner

It works fine for me with Qt6.9.1 with the windows11 style: int main(int argc, char *argv[]) { QApplication app(argc, argv); QTableWidget tw; tw.setRowCount(5); tw.setColumnCount(1); auto item = new QTableWidgetItem("Item"); tw.setItem(0, 0, item); QTimer::singleShot(2000, &tw, [&]() { tw.item(0, 0)->setCheckState(Qt::Checked); }); tw.show(); return app.exec(); } Please provide a minimal, compilable example of your problem.

@SuhasKrishanamurthy hi, Since you marked your thread as solved, can you share what you did / change to fix the situation ? It might help other people.
