Package jadex.commons.gui.jtreetable

Class JTreeTable.TreeTableCellEditor

  • All Implemented Interfaces:
    java.io.Serializable, javax.swing.CellEditor, javax.swing.table.TableCellEditor, javax.swing.tree.TreeCellEditor
    Enclosing class:
    JTreeTable
    public class JTreeTable.TreeTableCellEditor
extends javax.swing.DefaultCellEditor
    An editor that can be used to edit the tree column. This extends DefaultCellEditor and uses a JTextField (actually, TreeTableTextField) to perform the actual editing. reshape method in the JTextField component to nudge the textfield to the location tree would place it. Since JTreeTable will paint the tree behind the editor everything should just work. So, that is what we are doing here. Determining of the icon position will only work if the TreeCellRenderer is an instance of DefaultTreeCellRenderer. If you need custom TreeCellRenderers, that don't descend from DefaultTreeCellRenderer, and you want to support editing in JTreeTable, you will have to do something similiar.
