It seems undocumented, but the class QQmlAbstractUrlInterceptor was documented. > You can look for runtimeqml on GitHub for a use of it (disclaimer- I'm the > author and while it works for me it was not extensively tested ;-) > https://github.com/GIPdA/runtimeqml ). > > Remapping all qrc files to the filesystem path seems a bit overkill when using qt_add_qml_module() as we already have a perfectly good on disk QML module that the engine can use. Also in this case the qrc files are generated by CMake, I am not sure I can easily get the names of the qrc files. In the ends it is really just the "prefer" line in the qmldir that makes it impossible to use the on disk qml modules. For now I've found a solution, I just run a "sed" command to comment the "prefer" line in all the qmldir at the end of CMake configuration. It's a bit ugly though, I would prefer to set an option in qt_add_qml_module(). Side note, I've also found that the URL interceptor does not work when QML files are compiled with cachegen (which is the default when using qt_add_qml_module). I guess that is because the components are always in cache and the QML engine never needs to load them by URL. Cheers Benjamin
