Detailed Description

Provides an easy-to-use output stream for logging.

This class is almost a clone of QDebug, but it's focused on logging.
Also the way messages are handled is different as there can be multiple logging handlers attached (not just one).

Friends And Related Function Documentation

void attachGlobalLogHandler ( AbstractLogHandler *  handler )

related

Append handler to the global list of log handlers.

If the internal list of log handlers is empty then all pending log messages are flushed to handler.

Note that log messages are recorded when there is no log handler attached. In this case a log message is considered as "pending".

Log debugLog ( )

void detachGlobalLogHandler ( AbstractLogHandler *  handler )

related

Remove handler from the global list of log handlers.
