30 /** An extension of SimpleTreeModel which implements the
31 TreeTableModel interface. It supports a two-column "Name, Value"
32 interface and disabling of editing of the "Value" column. Because
33 of a bug in the implementation of JTreeTable, it always returns
34 "true" for isCellEditable of cells in the "Name" column;
35 otherwise, mouse clicks to open handles are not dispatched
36 properly. Users are responsible for calling setTreeEditable(false)
37 on the JTreeTable to make the names uneditable. */
