Direct Known Subclasses:

DetachedTextEditor

public class TextEditor
extends javax.swing.AbstractCellEditor
implements javax.swing.table.TableCellEditor

Cell editor class for cache table. This class uses a combination of a TextArea
and a JScrollPane to construct a flexible scrollable text box that
appears whenever a cell's value is too long to fit in a table's column

To use this class, all you need to do is to initialise a JTable object
and invoke the following method:
myTable.setDefaultEditor(Object.class, new TextEditor(myTable)); if you would like to use the same editor for all columns. Alternatively,
you could use myColumn.setCellEditor(new TextEditor(myTable)) to
use the editor for a specific table column.
