Class ListSelectionEvent

  +--java.util.EventObject

        +--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. A future release of Swing will provide support for long term persistence.

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). Atleast 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

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

getValueIsAdjusting

public boolean getValueIsAdjusting()
