Indeed. I'm still waiting for an explanation for the need for emit. I am trying as hard as I can to spot such a need, and failing. The apparent need is riding on a hypothesis that signals are special, but they aren't. They are just like all other functions, albeit generated functions, but in that sense no different from other functions that you didn't write. _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
