Constructor Detail

• DefaultGraphCellEditor

  public DefaultGraphCellEditor()

  Constructs a DefaultTreeCellEditor object for a JGraph using the specified renderer and a default editor. (Use this constructor for normal editing.)

• DefaultGraphCellEditor

  public DefaultGraphCellEditor​(GraphCellEditor editor)

  Constructs a DefaultTreeCellEditor object for a JTree using the specified renderer and the specified editor. (Use this constructor for specialized editing.)

  Parameters:

  editor - a TreeCellEditor object

Method Detail

• setBorderSelectionColor

  public void setBorderSelectionColor​(java.awt.Color newColor)

  Sets the color to use for the border.

• getBorderSelectionColor

  public java.awt.Color getBorderSelectionColor()

  Returns:

  the editing Font

  Configures the editor. Passed onto the realEditor.

  Specified by:

  getGraphCellEditorComponent in interface GraphCellEditor

  Parameters:

  graph - the JGraph that is asking the editor to edit This parameter can be null.

  isSelected - true if the cell is to be rendered with selection highlighting

  Returns:

  the component for editing

• getCellEditorValue

  public java.lang.Object getCellEditorValue()

  Returns the value currently being edited.

  Specified by:

  getCellEditorValue in interface javax.swing.CellEditor

• isCellEditable

  public boolean isCellEditable​(java.util.EventObject event)

  If the realEditor returns true to this message, prepareForEditing is messaged and true is returned.

  Specified by:

  isCellEditable in interface javax.swing.CellEditor

• shouldSelectCell

  public boolean shouldSelectCell​(java.util.EventObject event)

  Messages the realEditor for the return value.

  Specified by:

  shouldSelectCell in interface javax.swing.CellEditor

• stopCellEditing

  public boolean stopCellEditing()

  If the realEditor will allow editing to stop, the realEditor is removed and true is returned, otherwise false is returned.

  Specified by:

  stopCellEditing in interface javax.swing.CellEditor

• cancelCellEditing

  public void cancelCellEditing()

  Messages cancelCellEditing to the realEditor and removes it from this instance.

  Specified by:

  cancelCellEditing in interface javax.swing.CellEditor

• addCellEditorListener

  public void addCellEditorListener​(javax.swing.event.CellEditorListener l)

  Adds the CellEditorListener.

  Specified by:

  addCellEditorListener in interface javax.swing.CellEditor

• removeCellEditorListener

  public void removeCellEditorListener​(javax.swing.event.CellEditorListener l)

  Removes the previously added CellEditorListener l.

  Specified by:

  removeCellEditorListener in interface javax.swing.CellEditor

  public void valueChanged​(GraphSelectionEvent e)

  Resets lastPath.

  Specified by:

  valueChanged in interface GraphSelectionListener

  Parameters:

  e - the event that characterizes the change.

• actionPerformed

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

  Messaged when the timer fires, this will start the editing session.

  Specified by:

  actionPerformed in interface java.awt.event.ActionListener

• setGraph

  protected void setGraph​(JGraph newGraph)

  Sets the tree currently editing for. This is needed to add a selection listener.

• shouldStartEditingTimer

  protected boolean shouldStartEditingTimer​(java.util.EventObject event)

  Returns true if event is a MouseEvent and the click count is 1.

• canEditImmediately

  protected boolean canEditImmediately​(java.util.EventObject event)

  Returns true if event is null, or it is a MouseEvent with a click count > 2 and inHitRegion returns true.

• inHitRegion

  protected boolean inHitRegion​(double x,
                                double y)

  Should return true if the passed in location is a valid mouse location to start editing from. This is implemented to return false if x is <= the width of the icon and icon gap displayed by the renderer. In other words this returns true if the user clicks over the text part displayed by the renderer, and false otherwise.

• determineOffset

  protected void determineOffset​(JGraph graph,
                                 java.lang.Object value,

• createContainer

  protected java.awt.Container createContainer()

  Creates the container to manage placement of editingComponent.

• createGraphCellEditor

  protected GraphCellEditor createGraphCellEditor()

  This is invoked if a TreeCellEditor is not supplied in the constructor. It returns a TextField editor.
