ListDataEvent (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

javax.swing.event
class ListDataEvent

java.lang.Object
  java.util.EventObject
      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 JavaBeans^TM has been added to the java.beans package. Please see {@link java.beans.XMLEncoder}.

Field Summary
`static int`	`CONTENTS_CHANGED` Identifies one or more changes in the lists contents.
`static int`	`INTERVAL_ADDED` Identifies the addition of one or more contiguous items to the list
`static int`	`INTERVAL_REMOVED` Identifies the removal of one or more contiguous items from the list

Fields inherited from class java.util.EventObject
`source`

Constructor Summary
`ListDataEvent(Object source, int type, int index0, int index1)` Constructs a ListDataEvent object.

Method Summary
`int`	`getIndex0()` Returns the lower index of the range.
`int`	`getIndex1()` Returns the upper index of the range.
`int`	`getType()` Returns the event type.
`String`	`toString()` Returns a string representation of this ListDataEvent.

Field Detail

CONTENTS_CHANGED

public static final int CONTENTS_CHANGED

Identifies one or more changes in the lists contents.

INTERVAL_ADDED

public static final int INTERVAL_ADDED

Identifies the addition of one or more contiguous items to the list

INTERVAL_REMOVED

public static final int INTERVAL_REMOVED

Identifies the removal of one or more contiguous items from the list

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 {@link #CONTENTS_CHANGED}, {@link #INTERVAL_ADDED}, or {@link #INTERVAL_REMOVED}; index0 - one end of the new interval; index1 - the other end of the new interval

Method Detail

getIndex0

public int getIndex0()

Returns the lower index of the range. For a single element, this value is the same as that returned by {@link #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 {@link #getIndex0}.

Returns:: an int representing the upper index value

getType

public int getType()

Returns the event type. The possible values are:

{@link #CONTENTS_CHANGED}
{@link #INTERVAL_ADDED}
{@link #INTERVAL_REMOVED}

Returns:: an int representing the type 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.
