Class MessageCenter
java.lang.Object
org.apache.log4j.chainsaw.messages.MessageCenter
The MessageCenter is central place for all elements within Chainsaw to
notify the user of important information.
This class uses log4j itself quite significantly. All user message are sent to this classes log4j Logger (org.apache.log4j.chainsaw.message.MessageCenter).
To register a message with the user, you can use the addMessage(String) style methods on this class, or just as easily, get a handle to this class' logger, and log it as you would normally do.
All events to this logger are trapped within a Custom appender (additivity will be switched OFF), which stores the events in a ListModel.
You can invoke the setVisible() method to display all the messages
