I suppose this is convenient, but it also means creating a new function object for *every instance of the type*. A more "traditional" approach would only have *one* member function (that is called with the implicit 'this' parameter). Have you at least considered doing something similar here, i.e. instead of using a capturing lambda, instead use a stateless function that takes the owning class as a parameter? -- Matthew _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
