Creates new CellEditor

Method Detail

getTableCellEditorComponent

public java.awt.Component getTableCellEditorComponent(javax.swing.JTable table,
                                                      java.lang.Object value,
                                                      boolean isSelected,
                                                      int row,
                                                      int column)
returns celleditor component

Specified by:
getTableCellEditorComponent in interface javax.swing.table.TableCellEditor

getCellEditorValue

public java.lang.Object getCellEditorValue()
Returns the value contained in the editor

Specified by:
getCellEditorValue in interface javax.swing.CellEditor

isCellEditable

public boolean isCellEditable(java.util.EventObject anEvent)
Ask the editor if it can start editing using anEvent. anEvent is in the invoking component coordinate system. The editor can not assume the Component returned by getCellEditorComponent() is installed. This method is intended for the use of client to avoid the cost of setting up and installing the editor component if editing is not possible. If editing can be started this method returns true.

Specified by:
isCellEditable in interface javax.swing.CellEditor
Parameters:
anEvent - the event the editor should use to consider whether to begin editing or not.
Returns:
true if editing can be started.

shouldSelectCell(java.util.EventObject)

shouldSelectCell

public boolean shouldSelectCell(java.util.EventObject anEvent)
Tell the editor to start editing using anEvent. It is up to the editor if it want to start editing in different states depending on the exact type of anEvent. For example, with a text field editor, if the event is a mouse event the editor might start editing with the cursor at the clicked point. If the event is a keyboard event, it might want replace the value of the text field with that first key, etc. anEvent is in the invoking component's coordinate system. A null value is a valid parameter for anEvent, and it is up to the editor to determine what is the default starting state. For example, a text field editor might want to select all the text and start editing if anEvent is null. The editor can assume the Component returned by getCellEditorComponent() is properly installed in the clients Component hierarchy before this method is called.

The return value of shouldSelectCell() is a boolean indicating whether the editing cell should be selected or not. Typically, the return value is true, because is most cases the editing cell should be selected. However, it is useful to return false to keep the selection from changing for some types of edits. eg. A table that contains a column of check boxes, the user might want to be able to change those checkboxes without altering the selection. (See Netscape Communicator for just such an example) Of course, it is up to the client of the editor to use the return value, but it doesn't need to if it doesn't want to.

Specified by:
shouldSelectCell in interface javax.swing.CellEditor
Parameters:
anEvent - the event the editor should use to start editing.
Returns:
true if the editor would like the editing cell to be selected

isCellEditable(java.util.EventObject)

stopCellEditing

public boolean stopCellEditing()
Tell the editor to stop editing and accept any partially edited value as the value of the editor. The editor returns false if editing was not stopped, useful for editors which validates and can not accept invalid entries.

Specified by:
stopCellEditing in interface javax.swing.CellEditor
Returns:
true if editing was stopped

cancelCellEditing

public void cancelCellEditing()
Tell the editor to cancel editing and not accept any partially edited value.

Specified by:
cancelCellEditing in interface javax.swing.CellEditor

addCellEditorListener

public void addCellEditorListener(javax.swing.event.CellEditorListener l)
Add a listener to the list that's notified when the editor starts, stops, or cancels editing.

Specified by:
addCellEditorListener in interface javax.swing.CellEditor

Remove a listener from the list that's notified

Specified by:
removeCellEditorListener in interface javax.swing.CellEditor
Parameters:
l - the CellEditorListener
