All Implemented Interfaces:

public class ErrorStrip
extends javax.swing.JComponent

A component to sit alongside an RSyntaxTextArea that displays colored markers for locations of interest (parser errors, marked occurrences, etc.).

An ErrorStrip can be added to a UI like so:

 textArea = createTextArea();
 scrollPane = new RTextScrollPane(textArea, true);
 ErrorStrip es = new ErrorStrip(textArea);
 JPanel temp = new JPanel(new BorderLayout());
 temp.add(scrollPane);
 temp.add(es, BorderLayout.LINE_END);
