ListSelectionEvent

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 JavaBeansTM has been added to the java.beans package. Please see {@link java.beans.XMLEncoder}.

Constructors Summary
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.

param
firstIndex the first index that changed
param
lastIndex the last index that changed, lastIndex >= firstIndex
param
isAdjusting an indication that this is one of rapid a series of events

	super(source);
	this.firstIndex = firstIndex;
	this.lastIndex = lastIndex;
	this.isAdjusting = isAdjusting;

 return lastIndex;
public booleangetValueIsAdjusting()
Returns true if this is one of multiple change events.

return
true if this is one of a rapid series of events

 return isAdjusting;
public java.lang.StringtoString()
Returns a string that displays and identifies this object's properties.

return
a String representation of this object
