    Does each icon exist as a file somewhere? I assumed they were stored in some binary that would make them hard to access

    Hi, From a quick look, the former is to registry a QML type while the latter is to register an actual C++ object instance.

    @lyvvvv As far as I know Visual Studio supports CMake - why not using it directly instead of sln?

    Hi, You can start your application with the QT_DEBUG_PLUGINS environment variable set to 1 to get more information about what is happening. That said, why does your static Qt build try to load your system installed plugins ?

    I'm developping a RPG game. When I push the right-key and push the up-key simultaneously, event loop stops. Why? bool MapScene::event(QEvent *event) { if (event->type() == QEvent::KeyPress) { qDebug() << "event"; } return QGraphicsScene::event(event); } I tried at the upper event, but the result was the same. 1.When I move a character to the right direction, naturally I push the right-key. 2.When I change the direction, for example, I push the down-key suddenly. 3.The event is not called. To call the event, I must release completely the key button once, and then push another button. But I dislike such a way because it is not comfortable. Please tell me how to solve this problem.

    Hello, I am super happy and thrilled to see that Qt WebEngine (with Qt 6.9) compiles on WoA. The only little issue I have is that it is slow and that is because it currently uses the x64 compiler instead of the native one. That means it goes via emulation. Is there a way to avoid this?

    I made a batch script that I run every time I detect that the .qrc (or .ui) files have changed. It's all automated before launching the application.

    @1XU7 I dont think that you can use relative path to images if they are outside of main project (not inside resource file in project), because webassembly (.wasm project) is sandboxed and can see just what is inside "his" sandboxed filesystem. So i am not 100% on this but i think that only way to load external images is to specifie full path where there are hosted (for instance: myhost.com/images/image1.jpg)

    Hi! We have a bit more complex setup with a generic library that defines (multiple) qml_modules. These qml_modules are then consumed in projects. Projects are again separated into multiple qml_modules. The problem arises while we wanted to transition to QmlProject files from CMake (as the Qt for MCUs CMake API is deprecated). The project specific qml_module has C++ types that need to be used in Qml, hence we define a InterfaceFiles node in the QmlProject like the following: InterfaceFiles { files: [ "include/path/to/a/InterfaceHeader.h" ] MCU.qmlImports: [ "com.company.generic.component" ] } The compiler fails to resolve header includes in InterfaceHeader.h as the qmlprojectgenerator only gets CMake INCLUDE_DIRECTORIES of the CMake targets of the project feature qml_module passed as the --include-dirs parameter. The feature lib (created with qul_add_target(TARGET_NAME QML_PROJECT feature.qmlproject) does link to the generic qml_module with a target_link_libraries() call but this is too late for the internal workings of the qul_add_target macro. Somehow the QmlProject is missing a way to tell it which other qml_modules need to be linked/considered. The qul_add_target macro at some point internally is only evaluating the direct INCLUDE_DIRECTORIES which does not include the include directories of transitive dependencies. Here is another short overview of the structure: * generic-library - output: qml_module * project * feature-a - defines qml_module - depends on qml_module of generic-library - ERROR: the interface header files of this of this qml_module are unable to include headers of the generic-library when using .qmlproject files. * feature-xxx - defines qml_module - depends on qml_module of generic-library - additionally might depend on another feature of the project * project-lib - depends on all features * project-app - depends on project-lib Thx, Andi
