Well, so far you only questioned the scoped enum case and making an argument for the scoped enum case based on so far accepted rules for unscoped ones is valid. > > Therefore QQuickEventPoint::State::Pressed is no more verbose than > QQuickEventPoint::PressedState. > > Again, the policy does not mandate that in itâs current form in my reading of > it, > and even if it did, that would be a bad policy and we should fix it, not just > blindly > accept it as set in stone, because weâve followed it "for decades". To quote the policy: "By comparison the following example illustrates the dangers of missing type safety and giving general names to conventional enum values:" ... " One guideline for naming enum types is to repeat at least one element of the enum type name in each of the enum values" I think the policy is explicit. Whether you think it is bad is a different kind of thing. Please don't mix that. Personally, I think this naming rule has served us well and although it is not consistently applied the majority of enums does follow them. > > In summary, there is very little verbosity added even by existing rules. > > Mind > you, Qt has always favoured readability and accepted verbosity as a > consequence in times of code completion. > > Code completion (for those that use it), only helps with writing code, and as > we > all know, most time is spent reading code đ > > > There is one more very important aspect.

Frequent enough for it being the primary driver behind the introduction of scoped enums?!? Mind you even our own policies state this limitation of unscoped enums. -- Alex _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
