Class DefaultListSelectionModel

java.lang.Object

javax.swing.DefaultListSelectionModel

All Implemented Interfaces:

Serializable, Cloneable, ListSelectionModel

public class DefaultListSelectionModel
extends Object
implements ListSelectionModel, Cloneable, Serializable

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. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Method Summary

Modifier and Type	Method	Description
void	addListSelectionListener(ListSelectionListener l)	Add a listener to the list that's notified each time a change to the selection occurs.
void	addSelectionInterval(int index0, int index1)	Changes the selection to be the set union of the current selection and the indices between index0 and index1 inclusive.
void	clearSelection()	Change the selection to the empty set.
Object	clone()	Returns a clone of this selection model with the same selection.
protected void	fireValueChanged(boolean isAdjusting)	Notifies listeners that we have ended a series of adjustments.
protected void	fireValueChanged(int firstIndex, int lastIndex)	Notifies ListSelectionListeners that the value of the selection, in the closed interval firstIndex, lastIndex, has changed.
protected void	fireValueChanged(int firstIndex, int lastIndex, boolean isAdjusting)
int	getAnchorSelectionIndex()	Return the first index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval().
int	getLeadSelectionIndex()	Return the second index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval().
<T extends EventListener> T[]	getListeners(Class<T> listenerType)	Returns an array of all the objects currently registered as FooListeners upon this model.
ListSelectionListener[]	getListSelectionListeners()	Returns an array of all the list selection listeners registered on this DefaultListSelectionModel.
int	getMaxSelectionIndex()	Returns the last selected index or -1 if the selection is empty.
int	getMinSelectionIndex()	Returns the first selected index or -1 if the selection is empty.
int	getSelectionMode()	Returns the current selection mode.
boolean	getValueIsAdjusting()	Returns true if the selection 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	moveLeadSelectionIndex(int leadIndex)	Set the lead selection index, leaving all selection values unchanged.
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)	Changes 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)	Sets 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)	Changes the selection to be between index0 and index1 inclusive.
void	setSelectionMode(int selectionMode)	Sets the selection mode.
void	setValueIsAdjusting(boolean isAdjusting)	Sets the valueIsAdjusting property, which indicates whether or not upcoming selection changes should be considered part of a single change.
String	toString()	Returns a string that displays and identifies this object's properties.

DefaultListSelectionModel

public DefaultListSelectionModel()

Method Detail

getMinSelectionIndex

public int getMinSelectionIndex()

Returns the first selected index or -1 if the selection is empty.

Specified by:

getMinSelectionIndex in interface ListSelectionModel

getMaxSelectionIndex

public int getMaxSelectionIndex()

Returns the last selected index or -1 if the selection is empty.

Specified by:

getMaxSelectionIndex in interface ListSelectionModel

getValueIsAdjusting

public boolean getValueIsAdjusting()

Returns true if the selection is undergoing a series of changes.

Specified by:

getValueIsAdjusting in interface ListSelectionModel

Returns:

true if the selection is undergoing a series of changes

See Also:

ListSelectionModel.setValueIsAdjusting(boolean)

getSelectionMode

public int getSelectionMode()

Returns the current selection mode.

Specified by:

getSelectionMode in interface ListSelectionModel

Returns:

the current selection mode

See Also:

ListSelectionModel.setSelectionMode(int)

setSelectionMode

public void setSelectionMode(int selectionMode)

Sets the selection mode. The following list describes the accepted selection modes:

• ListSelectionModel.SINGLE_SELECTION - Only one list index can be selected at a time. In this mode, setSelectionInterval and addSelectionInterval are equivalent, both replacing the current selection with the index represented by the second argument (the "lead").
• ListSelectionModel.SINGLE_INTERVAL_SELECTION - Only one contiguous interval can be selected at a time. In this mode, addSelectionInterval behaves like setSelectionInterval (replacing the current selection), unless the given interval is immediately adjacent to or overlaps the existing selection, and can therefore be used to grow it.
• ListSelectionModel.MULTIPLE_INTERVAL_SELECTION - In this mode, there's no restriction on what can be selected.

Specified by:

setSelectionMode in interface ListSelectionModel

Throws:

IllegalArgumentException - if the selection mode isn't one of those allowed

ListSelectionModel.getSelectionMode()

isSelectedIndex

public boolean isSelectedIndex(int index)

Returns true if the specified index is selected.

Specified by:

isSelectedIndex in interface ListSelectionModel

isSelectionEmpty

public boolean isSelectionEmpty()

Returns true if no indices are selected.

Specified by:

isSelectionEmpty in interface ListSelectionModel

addListSelectionListener

public void addListSelectionListener(ListSelectionListener l)

Add a listener to the list that's notified each time a change to the selection occurs.

Specified by:
