How about have some method of the application that could load what to log or not log;
a simple set of 2 functions, each takes a QStringList of the categories:

// positive enabling (negative disable)
static void QMessageLogger::enableLogCategories(QStringList categoryList);
// positive disabling (negative enable)
static void QMessageLogger::disableLogCategories(QStringList categoryList);

// to enable verification of the above
static bool QMessageLogger::isPositiveEnable();
static bool QMessageLogger::isPositiveDisable();

// return the current list of categories loaded for positive enabling/disabling
static QStringList QMessageLogger::getCategories();
// return the build-time list of Qt categories
static QStringList QMessageLogger::getQtCategories();

Only one method could be used at a time.

It would be up to the application developer which to use and how to load it.

By default, all Qt message categories would be positively disabled.
