Modified: src/java/org/apache/log4j/chainsaw LogUI.java
Log:
If the Cyclic buffer is in use, added an EventCountListener so that
warning messages could be displayed when the buffer is taken over
the 75%, and 100% markers.
This message is displayed in the status bar regardless of the currently selected tab.
I would also like to add a small progress-bar-ish type thing to the status bar
to display the stats of the buffer for the currently selected tab.
