Examples of javax.swing.tree.DefaultTreeCellEditor

javax.swing.tree.DefaultTreeCellEditor
A TreeCellEditor. You need to supply an instance of DefaultTreeCellRenderer so that the icons can be obtained. You can optionally supply a TreeCellEditor that will be layed out according to the icon in the DefaultTreeCellRenderer. If you do not supply a TreeCellEditor, a TextField will be used. Editing is started on a triple mouse click, or after a click, pause, click and a delay of 1200 milliseconds.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see {@link java.beans.XMLEncoder}. @see javax.swing.JTree @author Scott Violet
