public class IconRowHeader extends JPanel implements MouseListener
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);
