svn commit: r693710 - /logging/chainsaw/trunk/src/main/java/org/apache/log4j/chainsaw/LogPanel.java

New Revision: 693710

URL: http://svn.apache.org/viewvc?rev=693710&view=rev
Log:
Slight optimization.  Found this with Yourkit, but if the Event Detail View is hidden, this logic is still getting fired...

That is, detailPain.isVisible() is true... even though we call setVisible(false) to toggle it.  

Instead, check the Preference model for the state, and exit early if it's not visible.
