Represents a single log message together with some data
that are used to decorate the log message.
The following variables may be used in the message and in msgFormat:
- {timestamp} Date and time of creation
- {typeNr} Type of the message in numeric format (0-3)
- {type} Type of the message in string format (DEBUG, WARNING, CRITICAL, FATAL)
- {thread} ID number of the thread
- {msg} Message text
- {xxx} For any user-defined logger variable
Plus some new variables since QT 5.0, only filled when compiled in debug mode:
- {file} Filename where the message was generated
- {function} Function where the message was generated
- {line} Line number where the message was generated
