ListSelectionEvent

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 {@code ListSelectionModel} implementation will keep the range as small as possible. {@code 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}.

isAdjusting
Constructors Summary
public ListSelectionEvent(Object source, int firstIndex, int lastIndex, boolean isAdjusting)
Represents a change in selection status between {@code firstIndex} and {@code lastIndex}, inclusive. {@code firstIndex} is less than or equal to {@code lastIndex}. The selection of at least one index within the range will have changed.

param
firstIndex the first index in the range, <= lastIndex
param
lastIndex the last index in the range, >= firstIndex
param
isAdjusting whether or not this is one in a series of multiple events, where changes are still being made

	super(source);
	this.firstIndex = firstIndex;
	this.lastIndex = lastIndex;
	this.isAdjusting = isAdjusting;
Methods Summary
public intgetFirstIndex()
Returns the index of the first row whose selection may have changed. {@code getFirstIndex() <= getLastIndex()}

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

 return firstIndex;
public intgetLastIndex()
Returns the index of the last row whose selection may have changed. {@code getLastIndex() >= getFirstIndex()}

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

 return lastIndex;
public booleangetValueIsAdjusting()
Returns whether or not this is one in a series of multiple events, where changes are still being made. See the documentation for {@link javax.swing.ListSelectionModel#setValueIsAdjusting} for more details on how this is used.

return
{@code true} if this is one in a series of multiple events, where changes are still being made

 return isAdjusting;
public java.lang.StringtoString()
Returns a {@code String} that displays and identifies this object's properties.

return
a String representation of this object

	String properties = 
	    " source=" + getSource() +  
            " firstIndex= " + firstIndex + 
            " lastIndex= " + lastIndex + 
	    " isAdjusting= " + isAdjusting +
            " ";
        return getClass().getName() + "[" + properties + "]";
