QtWidgets: use printf-style qWarning/qDebug where possible (I)
The printf-style version of QDebug expands to a lot less code than the std::ostream-style version. Of course, you pay in type safety (but compilers warn about it these days), you cannot stream complex Qt types and streaming QStrings is awkward, but in many cases you actually improve on readability. But the main reason is that something that's not supposed to be executed under normal operation has no business bloating executable code size. This is not an attempt at converting all qWarnings() to printf-style, only the low-hanging fruit. In this first part, replace qWarning() << "..."; with qWarning("..."); Change-Id: I1f6869b024103c98262f1deae014e0d7337a541c Reviewed-by: Friedemann Kleint <Friedemann.Kleint@theqtcompany.com> Reviewed-by: Olivier Goffart (Woboq GmbH) <ogoffart@woboq.com>
