I for one would really like to have an improved logging framework in Qt5 :) Since it's Christmas soon, I'd like to add one thing to the wishlist : A way to add a file/line info to the log. This way you'd be able to see where in the source code a specific message was raised . Syntax could e.g. be: qLog(QWidget).location(__FILE__, __LINE__) << "Created" << name; (Maybe __FILE__ , __LINE__ can be automatically retrieved by yet another macro? Not sure ...). For logs coming from .js (console.log(), console.debug() ...) the source location would automatically be set.
