Qt Creator and other tools

Thank you for posting this. Qt Creator 19.0.2 has a CMake find package dependency provider that checks to see if Qt packages are missing, and if so, then you can get an Issue with a link to automagically install the missing Qt component. But there is an issue when a Qt component has a dependency on other Qt components that might have missing dependencies. I have tried a Qt Widgets "Hello World" with missing system dev packages. With Qt Creator 19.0.2 and a Qt SDK Qt 6.11.1 I get this in General Messages: [cmake] Running /snap/bin/cmake -S /home/cristian/Projects/C++/HelloQtWidgets -B /home/cristian/Projects/C++/HelloQtWidgets/build/Desktop_Qt_6_11_1-Debug -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_COLOR_DIAGNOSTICS:BOOL=ON -DCMAKE_CXX_COMPILER:FILEPATH=/usr/lib/ccache/aarch64-linux-gnu-g++-13 -DCMAKE_C_COMPILER:FILEPATH=/usr/lib/ccache/aarch64-linux-gnu-gcc-13 -DCMAKE_GENERATOR:STRING=Ninja -DCMAKE_MAKE_PROGRAM:STRING=/usr/bin/ninja -DCMAKE_PREFIX_PATH:PATH=/home/cristian/Qt/6.11.1/gcc_arm64 -DCMAKE_PROJECT_INCLUDE_BEFORE:FILEPATH=/home/cristian/Projects/C++/HelloQtWidgets/build/Desktop_Qt_6_11_1-Debug/.qtcreator/cmake-helper/qtcreator-project.cmake -DQT_CREATOR_ENABLE_MAINTENANCE_TOOL_PROVIDER:BOOL=ON -DQT_CREATOR_ENABLE_PACKAGE_MANAGER_SETUP:BOOL=ON -DQT_ENABLE_QML_DEBUG:BOOL=ON -DQT_QMAKE_EXECUTABLE:FILEPATH=/home/cristian/Qt/6.11.1/gcc_arm64/bin/qmake in /home/cristian/Projects/C++/HelloQtWidgets/build/Desktop_Qt_6_11_1-Debug.

@Chris-Kawa Thank you. This started happening after I rolled back from VS 18.6.2 to 18.5.3, I tried to follow your advice, but the VS Installer complained about missing "stuff". In the end I had to completely uninstall VS and re-install - most annoying! However the good news is that "normal service" has now been resumed!

I had a similar problem , It was fixed only by deleting build folder and rebuilding again

@chenwj said in Qt Creator, VSCode or CLion?: Meanwhile, using AI features in Qt Creator requires a commercial license. With Qt Creator 20 you can use the ACP Client to connect to an ACP Agent like Claude Agent, Codex CLI, or OpenCode and do any AI work. The ACP Client plugin is part of the OpenSource Qt Creator.

Ha, I got Jira to work. I'll keep an eye on the issue, thanks a lot!

@Robert-Hairgrove Fair enough. If it were me I would try a quick one line Qt GUI program of my own to see whether it respects --qwindowgeometry (that's one of the command line arguments any Qt program picks up), plus save/restore if you're wanting to check that, to see where you start from.

Hi, Which version of Qt Creator are you talking about ?

I have the same problem but in windows 10... did you find any solution ?

@galkinvv Thanks for your workaround for this. It got me up and running. According to this We should be able to use mount-libexec and libexec-mount-point for this. However, I tried them and they don't work. Have you found out anything more about this? Kevin

[Using QtCreator 18.0.2 and Qt 6.7.2] I had the same issue and I solved it by adding "NO_CACHEGEN" under "qt_add_qml_module" in my CMakeLists.txt file. As far as I understand, this problem occurs because the Preview uses the file under build folder but your changes occur on your projects file (which are not exactly the same file) and this tag disables caching and thus solves the problem. qt_add_qml_module(appXXX URI XXX VERSION 1.0 NO_CACHEGEN

@hskoglund Using a timer can be anything between a waste of time and vain hope. It depends on the operating system, how showMaximized(), showNormal() and the like are handled. QWidget::windowState() reflects what has been ordered to the window manager. The problem is that the widget's geometry can change twice. First time when showMaximized() has been processed and widget->windowState().testFlag(Qt::WindowMaximized) returns true. Second time, when the window manager has applied decorations (i.e. title bar and window handles). A good place to look for inspiration is tst_QWidget::showMaximized() and showFullScreen(). The QTRY_ macros generally process events until either the predicate is true or a timeout is hit. They're not available in applications, but you can write your own methods that work for your use case.

@Andy314 and @Udo-Alt I tried to reproduce the problem, but could not reproduce this bug. Can one of you give exact instructions with sample code to reproduce this problem? Then it would be possible to create a fix. Regards
