fireValueChanged

protected void fireValueChanged(boolean isAdjusting)

Notify listeners that we have ended a series of adjustments.

fireValueChanged

protected void fireValueChanged(int firstIndex,
                    int lastIndex)

Notify ListSelectionListeners that the value of the selection, in the closed interval firstIndex,lastIndex, has changed.

fireValueChanged

protected void fireValueChanged(int firstIndex,
                    int lastIndex,
                    boolean isAdjusting)

Parameters:

firstIndex - The first index in the interval.

index1 - The last index in the interval.

isAdjusting - True if this is the final change in a series of them.

setLeadAnchorNotificationEnabled

public void setLeadAnchorNotificationEnabled(boolean flag)

Sets the value of the leadAnchorNotificationEnabled flag.

See Also:

isLeadAnchorNotificationEnabled()

isLeadAnchorNotificationEnabled

public boolean isLeadAnchorNotificationEnabled()

Returns the value of the leadAnchorNotificationEnabled flag. When leadAnchorNotificationEnabled is true the model generates notification events with bounds that cover all the changes to the selection plus the changes to the lead and anchor indices. Setting the flag to false causes a norrowing of the event's bounds to include only the elements that have been selected or deselected since the last change. Either way, the model continues to maintain the lead and anchor variables internally. The default is true.

Returns:

the value of the leadAnchorNotificationEnabled flag

setLeadAnchorNotificationEnabled(boolean)

clearSelection

public void clearSelection()

Specified by:

clearSelection in interface javax.swing.ListSelectionModel

setSelectionInterval

public void setSelectionInterval(int index0,
                        int index1)

Specified by:

setSelectionInterval in interface javax.swing.ListSelectionModel

addSelectionInterval

public void addSelectionInterval(int index0,
                        int index1)

Specified by:

addSelectionInterval in interface javax.swing.ListSelectionModel

removeSelectionInterval

public void removeSelectionInterval(int index0,
                           int index1)

Specified by:

removeSelectionInterval in interface javax.swing.ListSelectionModel

insertIndexInterval

public void insertIndexInterval(int index,
                       int length,
                       boolean before)

Insert length indices beginning before/after index. If the value at index is itself selected, set all of the newly inserted items, otherwise leave them unselected. This method is typically called to sync the selection model with a corresponding change in the data model.

Specified by:

insertIndexInterval in interface javax.swing.ListSelectionModel

removeIndexInterval

public void removeIndexInterval(int index0,
                       int index1)

Remove the indices in the interval index0,index1 (inclusive) from the selection model. This is typically called to sync the selection model width a corresponding change in the data model. Note that (as always) index0 need not be <= index1.

Specified by:

removeIndexInterval in interface javax.swing.ListSelectionModel

setValueIsAdjusting

public void setValueIsAdjusting(boolean isAdjusting)

Specified by:

setValueIsAdjusting in interface javax.swing.ListSelectionModel

toString

public java.lang.String toString()

Returns a string that displays and identifies this object's properties.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this object

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a clone of the reciever with the same selection. listenerLists are not duplicated.

Overrides:

clone in class java.lang.Object

Throws:

java.lang.CloneNotSupportedException - if the receiver does not both (a) implement the Cloneable interface and (b) define a clone method.

getAnchorSelectionIndex

public int getAnchorSelectionIndex()

Specified by:

getAnchorSelectionIndex in interface javax.swing.ListSelectionModel

getLeadSelectionIndex

public int getLeadSelectionIndex()

Specified by:

getLeadSelectionIndex in interface javax.swing.ListSelectionModel

setAnchorSelectionIndex

public void setAnchorSelectionIndex(int anchorIndex)

Set the anchor selection index, leaving all selection values unchanged. If leadAnchorNotificationEnabled is true, send a notification covering the old and new anchor cells.

Specified by:

setAnchorSelectionIndex in interface javax.swing.ListSelectionModel

See Also:

getAnchorSelectionIndex(), setLeadSelectionIndex(int)

setLeadSelectionIndex

public 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. If the value at the anchor index is selected, first clear all the values in the range [anchor, oldLeadIndex], then select all the values values in the range [anchor, newLeadIndex], where oldLeadIndex is the old leadIndex and newLeadIndex is the new one.

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.
