With new classes in Qt6, I have generally preferred using scoped enums, but found several instances were it didn't make sense. For instance using QColorSpace::SRgb and QColorSpace::AdobeRgb for predefined color-spaces, where all other enums in QColorSpace are scoped.
Wasn't there a new C++ proposal for decoupling the two separate features of enum class? Best regards Allan -- Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
