Isn't that true of any function call though ? Any function could end up deleting this, or trigerring code in another thread, or anything. For example, a normal function call could end up emiting a signal, and as such, any function could be as dangerous as a signal. The other problem with emit, is that it's not required. So its absence doesn't mean a signal is not being emitted. _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
