Class ListSelectionEvent

        +--javax.swing.event.ListSelectionEvent

All Implemented Interfaces:

Serializable

public class ListSelectionEvent

extends EventObject

An event that characterizes a change in the current selection. The change is limited to a row interval. ListSelectionListeners will generally query the source of the event for the new selected status of each potentially changed row.

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 XMLEncoder.

Constructor Detail

 

ListSelectionEvent

public ListSelectionEvent(Object source,
                          int firstIndex,
                          int lastIndex,
                          boolean isAdjusting)

Represents a change in selection status between firstIndex and lastIndex inclusive (firstIndex is less than or equal to lastIndex). At least one of the rows within the range will have changed, a good ListSelectionModel implementation will keep the range as small as possible.

Parameters:

firstIndex - the first index that changed

lastIndex - the last index that changed, lastIndex >= firstIndex

isAdjusting - an indication that this is one of rapid a series of events

Method Detail

 

getFirstIndex

public int getFirstIndex()

Returns the index of the first row whose selection may have changed.

Returns:

the first row whose selection value may have changed, where zero is the first row

 

getLastIndex

public int getLastIndex()

Returns the index of the last row whose selection may have changed.

Returns:

the last row whose selection value may have changed, where zero is the first row

 

getValueIsAdjusting

public boolean getValueIsAdjusting()

Returns true if this is one of multiple change events.

Returns:

true if this is one of a rapid series of events

 

toString

public String toString()

Returns a string that displays and identifies this object's properties.

Overrides:

toString in class EventObject

Returns:

a String representation of this object
