Class ListSelectionEvent
java.lang.Object | +--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.

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
| 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.
