      As in summary.

      Example code:

       

      int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QObject::connect(&a, &QApplication::paletteChanged, []{ qDebug() << "Not gonna happen :("; });
    a.setPalette(QPalette(Qt::red));
    return a.exec();
}

      The signal is defined in QGuiApplication but QApplication doesn't seem to emit it.
