所有已实现的接口:

javax.swing.plaf.UIResource, javax.swing.text.Highlighter

直接已知子类:

RSyntaxTextAreaHighlighter

public class RTextAreaHighlighter
extends javax.swing.plaf.basic.BasicTextUI.BasicHighlighter

The highlighter implementation used by RTextAreas. It knows to always paint "mark all" highlights below selection highlights.

Most of this code is copied from javax.swing.text.DefaultHighlighter; unfortunately, we cannot re-use much of it since it is package private.

install

public void install(javax.swing.text.JTextComponent c)

指定者:
