java.lang.Object | +--javax.swing.DefaultListSelectionModel
Default data model for list selections.
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. A future release of Swing will provide support for long term persistence.

|
int |
getAnchorSelectionIndex()
Return the first index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval(). |

int |
getSelectionMode()
Returns the current selection mode. |
boolean |
getValueIsAdjusting()
Returns true if the value is undergoing a series of changes. |
void |
insertIndexInterval(int index,
int length,
boolean before)
Insert length indices beginning before/after index. |
boolean |
isLeadAnchorNotificationEnabled()
Returns the value of the leadAnchorNotificationEnabled flag. |
boolean |
isSelectedIndex(int index)
Returns true if the specified index is selected. |
boolean |
isSelectionEmpty()
Returns true if no indices are selected. |
void |
removeIndexInterval(int index0,
int index1)
Remove the indices in the interval index0,index1 (inclusive) from the selection model. |
void |
removeListSelectionListener(ListSelectionListener l)
Remove a listener from the list that's notified each time a change to the selection occurs. |
void |
removeSelectionInterval(int index0,
int index1)
Change the selection to be the set difference of the current selection and the indices between index0 and index1 inclusive. |
void |
setAnchorSelectionIndex(int anchorIndex)
Set the anchor selection index, leaving all selection values unchanged. |
void |
setLeadAnchorNotificationEnabled(boolean flag)
Sets the value of the leadAnchorNotificationEnabled flag. |
void |
setLeadSelectionIndex(int leadIndex)
Set the lead selection index, ensuring that values between the anchor and the new lead are either all selected or all deselected. |
void |
setSelectionInterval(int index0,
int index1)
Change the selection to be between index0 and index1 inclusive. |
void |
setSelectionMode(int selectionMode)
Set the selection mode. |
void |
setValueIsAdjusting(boolean isAdjusting)
This property is true if upcoming changes to the value of the model should be considered a single event. |
String |
toString()
Returns a string that displays and identifies this object's properties. |

SINGLE_SELECTION
Only one list index can be selected at a time. In this
mode the setSelectionInterval and addSelectionInterval
methods are equivalent, and only the second index
argument (the "lead index") is used.
SINGLE_INTERVAL_SELECTION
One contiguous index interval can be selected at a time.
In this mode setSelectionInterval and addSelectionInterval
are equivalent.
MULTIPLE_INTERVAL_SELECTION
In this mode, there's no restriction on what can be selected.

If the value at the anchor index is not selected, do the same thing in reverse, selecting values in the old range and deslecting values in the new one.
Generate a single event for this change and notify all listeners. For the purposes of generating minimal bounds in this event, do the operation in a single pass; that way the first and last index inside the ListSelectionEvent that is broadcast will refer to cells that actually changed value because of this method. If, instead, this operation were done in two steps the effect on the selection state would be the same but two events would be generated and the bounds around the changed values would be wider, including cells that had been first cleared only to later be set.
This method can be used in the mouseDragged() method of a UI class to extend a selection.
