public class EnhancedJTextArea
extends javax.swing.JTextArea
implements cynosurex.internal.CommonInterface

EnhancedJTextArea enhances the standard JTextArea class by creating a multithreaded JTextArea to calculate the current line and column position.

The thread is set to minimum priority, sleeps, and only wakes up to do the calculation when the cursor position changes.
