FoldingAwareIconRowHeader

public class IconRowHeader
extends javax.swing.JPanel
implements java.awt.event.MouseListener

Renders icons in the Gutter. This can be used to visually mark lines containing syntax errors, lines with breakpoints set on them, etc.

This component has built-in support for displaying icons representing "bookmarks;" that is, lines a user can cycle through via F2 and Shift+F2. Bookmarked lines are toggled via Ctrl+F2, or by clicking in the icon area at the line to bookmark. In order to enable bookmarking, you must first assign an icon to represent a bookmarked line, then actually enable the feature. This is actually done on the parent Gutter component:

 Gutter gutter = scrollPane.getGutter();
 gutter.setBookmarkIcon(new ImageIcon("bookmark.png"));
 gutter.setBookmarkingEnabled(true);
