Detailed Description

Interface for showing messages from QGIS in GUI independent way.

This class provides abstraction of a dialog for showing output to the user. By default QgsMessageConsoleOutput will be used if not overridden with other message output creator function.

QGIS application uses QgsMessageView class for displaying a dialog to the user.

Object deletes itself when it's not needed anymore. Children should use signal destroyed() to notify the deletion
