Class ListSelectionEvent

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.

Constructors

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. The selection of at least one index within the range will have changed.

Parameters:

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

Methods

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.

Overrides:

toString in class EventObject

Returns:

a String representation of this object
