Class JTreeTable.TreeTableCellEditor

java.lang.Object

javax.swing.AbstractCellEditor

javax.swing.DefaultCellEditor

jadex.commons.gui.jtreetable.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.

Overridden to determine an offset that tree would place the editor at. The offset is determined from the getRowBounds JTree method, and additionally from the icon DefaultTreeCellRenderer will use.
