QtWidgets: eradicate Q_FOREACH loops [QVarLengthArray, std containers]
Q_FOREACH over a QVarLengthArray or std containers
is a particularly bad idea (because of the deep
copy that Q_FOREACH then performs).
Use C++11 range-for (without qAsConst(), because
neither QVLA nor std containers are CoW).
Saves 5.7KiB in text size on optimized GCC 5.3
Linux AMD64 builds.
