QtDebug: Include file, line, function information
Record the file, line, and function where a qDebug, qWarning, qCritical
or qFatal call happens, and make this information available in a custom
message handler.
The patch uses the C preprocessor to replace qDebug, qWarning, ... with
a line that also records the current file, line, and function. Custom
message handlers can access this information via a new QMessageLogContext
argument.
