Class JLogoutputFrame

java.lang.Object
  jmri.util.JLogoutputFrame

public class JLogoutputFrame
extends Object

A standalone window for receiving and displaying log outputs

Singleton pattern

The original version deferred initialization onto the Swing thread; this version does it inline, and must be invoked from the Swing thread.

The Frame and the appender are not shown by initializing it but only made ready to receive all log output. It can later be set to visible if desired. TODO: implement also a enable() and disable() method in order to have a minimal impact on performance if not used.
