CPP Classes not showing in content browser

Novice here, probably doing something stupid.

If I create a class that is a child of AActor (e.g. class TESTGAME_API ABuilder : public AActor) then all is well and I can see it in the content browser. If I create a standard Class (e.g. class TESTGAME_API DungeonLevel) without a parent class then it does not show up in the content browser. I can use the class in Unreal (from a class that has AActor as a parent) and everything works as expected, I just can’t see it in the browser. If I explore the folder in Windows then I can see all my files there as expected.

I am creating the classes by right clicking in the content browser, “new c++ class” and selecting none for the parent. The class then opens in Visual Studio, but is not visible in the content browser.

I have tried removing Saved, Intermediate and Binaries, regenerating VS project files and rebuilding. Everything remains fine, except I can’t see the c++ classes in the Content Browser.

Question: Is it supposed to work this way?

I think it is because normal standard C++ class is not replected to UE Editor

OK. It would be nice if it was, so you could open the files easily from within the UE editor. But at least I’ve not just done something silly. Thanks for the reply.
