This particular warning is from clazy, and is trying to tell you that you're using 'emit' on a function that is not marked as signal in the declaration using (Q_SIGNAL/signals: sections)

Anyhow, I think there was a recent issue with this warning that caused false positives: https://bugreports.qt.io/browse/QTCREATORBUG-25165

As a workaround, you can disable this very clazy check , see https://doc.qt.io/qtcreator/creator-clang-tools.html

Or you give the Qt Creator 4.15.0 RC a try, where it should be fixed, too 😊
