javax.swing.event: public class: ListSelectionEvent

javax.swing.event
public class: ListSelectionEvent [javadoc | source]

java.lang.Object
   java.util.EventObject
      javax.swing.event.ListSelectionEvent

All Implemented Interfaces:
Serializable

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 JavaBeans^TM has been added to the java.beans package. Please see java.beans.XMLEncoder .

Constructor:

Constructor:
public ListSelectionEvent(Object source, int firstIndex, int lastIndex, boolean isAdjusting) { super(source); this.firstIndex = firstIndex; this.lastIndex = lastIndex; this.isAdjusting = 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. 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

 public ListSelectionEvent(Object source,
    int firstIndex,
    int lastIndex,
    boolean isAdjusting) {
        super(source);
        this.firstIndex = firstIndex;
        this.lastIndex = lastIndex;
        this.isAdjusting = 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.

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

Method from javax.swing.event.ListSelectionEvent Detail:
public int getFirstIndex() { return firstIndex; } Returns the index of the first row whose selection may have changed. {@code getFirstIndex() <= getLastIndex()}
public int getLastIndex() { return lastIndex; } Returns the index of the last row whose selection may have changed. {@code getLastIndex() >= getFirstIndex()}
public boolean getValueIsAdjusting() { return isAdjusting; } Returns whether or not this is one in a series of multiple events, where changes are still being made. See the documentation for javax.swing.ListSelectionModel#setValueIsAdjusting for more details on how this is used.
public String toString() { String properties = " source=" + getSource() + " firstIndex= " + firstIndex + " lastIndex= " + lastIndex + " isAdjusting= " + isAdjusting + " "; return getClass().getName() + "[" + properties + "]"; } Returns a {@code String} that displays and identifies this object's properties.
