Detailed Description

Interface for logging messages from QGIS in GUI independent way.

This class provides abstraction of a tabbed window for showing messages to the user. By default QgsMessageLogOutput will be used if not overridden with another message log creator function.

QGIS application uses QgsMessageLog class for logging messages in a dockable window for the user.
