The SLogger is a component, to assign error handling to a form. The SLogger is a not visual component and will not be displayed in the application.

The SLogger allows the selection of a Logger handler, that controls the error handling at runtime of the application form. Also Commands or Macros and Command classes or Handler classes can be used aus logger handler.

The SLogger differs between three diffrent error events, wich can get an own logger. Bei auftreten eines Fehler während der Laufzeit wird nur einer der drei möglichen Logger ausgelöst. Werden meherer Loggerhandler für ein Fehlerevent benötigt, können weitere SLogger in das Formular eingefügt werden.

When error arises at run time only one of the three possible logger is triggerd. If more logger handler are needed for an error event, further SLogger can be inserted into the form.
