From d394ca7f27197cfbfc28eb9a08eb0db261dd9d3d Mon Sep 17 00:00:00 2001 From: Kai Koehne Date: Tue, 17 Jan 2012 16:20:45 +0100 Subject: 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.
