All Implemented Interfaces:

javax.swing.text.TabExpander
```
public class TextAreaPainter
extends javax.swing.JComponent
implements javax.swing.text.TabExpander
```
The text area painter is the component responsible for displaying the text of the current buffer. The only methods in this class that should be called by plugins are those for adding and removing text area extensions.
