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 selection. The change is limited to a a single inclusive interval. The selection of at least one index within the range will have changed. A decent ListSelectionModel
implementation will keep the range as small as possible. 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™ has been added to the java.beans
package. Please see XMLEncoder
.

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
. The selection of at least one index within the range will have changed.
- Parameters:
-
source
- theObject
on which the event initially occurred -
firstIndex
- the first index in the range, <= lastIndex -
lastIndex
- the last index in the range, >= firstIndex -
isAdjusting
- whether or not this is one in a series of multiple events, where changes are still being made
Method Detail
getFirstIndex
public int getFirstIndex()
Returns the index of the first row whose selection may have changed. getFirstIndex() <= getLastIndex()
- 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. getLastIndex() >= getFirstIndex()
- Returns:
- the last row whose selection value may have changed, where zero is the first row
getValueIsAdjusting
public boolean getValueIsAdjusting()
Returns whether or not this is one in a series of multiple events, where changes are still being made. See the documentation for ListSelectionModel.setValueIsAdjusting(boolean)
for more details on how this is used.
- Returns:
-
true
if this is one in a series of multiple events, where changes are still being made
toString
public String toString()
Returns a String
that displays and identifies this object's properties.
