Class ModelTreeNodeEditor

    java.lang.Object
      javax.swing.AbstractCellEditor
          weka.gui.ensembleLibraryEditor.tree.ModelTreeNodeEditor

All Implemented Interfaces:
  java.awt.event.ActionListener, java.awt.event.ItemListener, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, javax.swing.CellEditor, javax.swing.tree.TreeCellEditor

    public class ModelTreeNodeEditor

extends javax.swing.AbstractCellEditor
implements javax.swing.tree.TreeCellEditor, java.awt.event.ItemListener, java.beans.PropertyChangeListener, java.awt.event.ActionListener

This class is in charge of dynamically creating editor GUI objects on demand for the main JTree class that will display our Classifier tree model of parameters. This is in fact the CellEditor class that is registered with our tree.

Basically it delegates much of the work to the various NodeEditor classes found in this package. All it really has to do is detect what of node it is and then instantiate an editor of the appropriate type.

Constructor Summary
`ModelTreeNodeEditor(javax.swing.JTree tree)` default Constructor

Method Summary
`void` | `actionPerformed(java.awt.event.ActionEvent e)` The item Listener that gets registered with all node editors that have a widget that had actionPerformed events.
`java.lang.Object` | `getCellEditorValue()` I'm supposed to implemnent this as part of the TreeCellEDitor interface.
`java.awt.Component` | `getTreeCellEditorComponent(javax.swing.JTree tree, java.lang.Object value, boolean selected, boolean expanded, boolean leaf, int row)` This method uses the ModelTreeNodeRenderer class to get the individual editors and then registers this classes editing event listeners with them
`boolean` | `isCellEditable(java.util.EventObject event)` This tells the JTree whether or not to let nodes in the tree be edited.
`void` | `itemStateChanged(java.awt.event.ItemEvent e)` The item Listener that gets registered with all node editors that have a widget that had itemStateChangeg events.
`void` | `propertyChange(java.beans.PropertyChangeEvent evt)` The prtopertyListener that gets registered with all node editors that have a widget that had propertyStateChangeg events.

Constructor Detail

### ModelTreeNodeEditor

    public ModelTreeNodeEditor(javax.swing.JTree tree)

  default Constructor

  Parameters:
    `tree` - the tree to use

Method Detail

### getCellEditorValue

    public java.lang.Object getCellEditorValue()

  I'm supposed to implemnent this as part of the TreeCellEDitor interface. however, it's not necessary for this class so it returns null.

  Specified by:
    `getCellEditorValue` in interface `javax.swing.CellEditor`
  Returns:
    always null

### isCellEditable

    public boolean isCellEditable(java.util.EventObject event)

  This tells the JTree whether or not to let nodes in the tree be edited. Basically all this does is return true for all nodes that aren't PropertyNodes - which don't have any interactive widgets

  Specified by:
    `isCellEditable` in interface `javax.swing.CellEditor`
  Overrides:
    `isCellEditable` in class `javax.swing.AbstractCellEditor`
  Parameters:
    `event` - the event
  Returns:
    true if editable

### getTreeCellEditorComponent

    public java.awt.Component getTreeCellEditorComponent(javax.swing.JTree tree,
                                                         java.lang.Object value,
                                                         boolean selected,
                                                         boolean expanded,
                                                         boolean leaf,
                                                         int row)

  This method uses the ModelTreeNodeRenderer class to get the individual editors and then registers this classes editing event listeners with them

  Specified by:
    `getTreeCellEditorComponent` in interface `javax.swing.tree.TreeCellEditor`
  Parameters:
    `tree` - the associated tree
    `value` - the value
    `selected` - true if item is selected
    `expanded` - true if it is expanded
    `leaf` - true if it is a leaf
    `row` - the row in the tree
  Returns:
    the rendering component

### itemStateChanged

    public void itemStateChanged(java.awt.event.ItemEvent e)

  The item Listener that gets registered with all node editors that have a widget that had itemStateChangeg events. It just fires the editing stopped event.

  Specified by:
    `itemStateChanged` in interface `java.awt.event.ItemListener`
  Parameters:
    `e` - the event

### propertyChange

    public void propertyChange(java.beans.PropertyChangeEvent evt)

  The prtopertyListener that gets registered with all node editors that have a widget that had propertyStateChangeg events. It just fires the editing stopped event.

  Specified by:
    `propertyChange` in interface `java.beans.PropertyChangeListener`
  Parameters:
    `evt` - the event

### actionPerformed

    public void actionPerformed(java.awt.event.ActionEvent e)

  The item Listener that gets registered with all node editors that have a widget that had actionPerformed events. It just fires the editing stopped event.

  Specified by:
    `actionPerformed` in interface `java.awt.event.ActionListener`
  Parameters:
    `e` - the event
