Class ListDataEvent

java.lang.Object
  extended by java.util.EventObject
      extended by javax.swing.event.ListDataEvent
All Implemented Interfaces:
Serializable

public class ListDataEvent
extends EventObject

Defines an event that encapsulates changes to a list.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

Constructor Detail

ListDataEvent

public ListDataEvent(Object source,
                     int type,
                     int index0,
                     int index1)
Constructs a ListDataEvent object. If index0 is > index1, index0 and index1 will be swapped such that index0 will always be <= index1.

Parameters:
source - the source Object (typically this)
type - an int specifying CONTENTS_CHANGED, INTERVAL_ADDED, or INTERVAL_REMOVED
index0 - one end of the new interval
index1 - the other end of the new interval
Method Detail

getType

public int getType()
Returns the event type. The possible values are:

Returns:
an int representing the type value

getIndex0

public int getIndex0()
Returns the lower index of the range. For a single element, this value is the same as that returned by getIndex1().

Returns:
an int representing the lower index value

getIndex1

public int getIndex1()
Returns the upper index of the range. For a single element, this value is the same as that returned by getIndex0().

Returns:
an int representing the upper index value

toString

public String toString()
Returns a string representation of this ListDataEvent. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:
toString in class EventObject
Returns:
a string representation of this ListDataEvent.
Since:
1.4
