OpenJDK 27 · javax.swing.event.ListSelectionEvent · APIdia, the JavaDoc alternative

An event that characterizes a change in selection. The change is limited to 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 java.beans.XMLEncoder.

ListSelectionEvent	back to 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`. The selection of at least one index within the range will have changed. Parameters source:Object the `Object` on which the event initially occurred firstIndex:int the first index in the range, <= `lastIndex` lastIndex:int the last index in the range, >= `firstIndex` isAdjusting:boolean whether or not this is one in a series of multiple events, where changes are still being made

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:Object: the Object on which the event initially occurred
firstIndex:int: the first index in the range, <= lastIndex
lastIndex:int: the last index in the range, >= firstIndex
isAdjusting:boolean: whether or not this is one in a series of multiple events, where changes are still being made
