Method Detail

setSelectionInterval

public void setSelectionInterval(int index0,
                                 int index1)

Enabled: Change the selection to be between index0 and index1 inclusive. If this represents a change to the current selection, then notify each ListSelectionListener. Note that index0 doesn't have to be less than or equal to index1.

Parameters:

index0 - one end of the interval.

index1 - other end of the interval

See Also:

addListSelectionListener(javax.swing.event.ListSelectionListener)

addSelectionInterval

public void addSelectionInterval(int index0,
                                 int index1)

Enabled: Change the selection to be the set union of the current selection and the indices between index0 and index1 inclusive. If this represents a change to the current selection, then notify each ListSelectionListener. Note that index0 doesn't have to be less than or equal to index1.

Parameters:

index0 - one end of the interval.

index1 - other end of the interval

See Also:

addListSelectionListener(javax.swing.event.ListSelectionListener)

removeSelectionInterval

public void removeSelectionInterval(int index0,
                                    int index1)

Enabled: Change the selection to be the set difference of the current selection and the indices between index0 and index1 inclusive. If this represents a change to the current selection, then notify each ListSelectionListener. Note that index0 doesn't have to be less than or equal to index1.

Parameters:

index0 - one end of the interval.

index1 - other end of the interval

addListSelectionListener(javax.swing.event.ListSelectionListener)

getMinSelectionIndex

public int getMinSelectionIndex()

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

getMaxSelectionIndex

public int getMaxSelectionIndex()

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

isSelectedIndex

public boolean isSelectedIndex(int index)

Enabled: Returns true if the specified index is selected.

getAnchorSelectionIndex

public int getAnchorSelectionIndex()

Enabled: Return the first index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval(). The most recent index0 is considered the "anchor" and the most recent index1 is considered the "lead". Some interfaces display these indices specially, e.g. Windows95 displays the lead index with a dotted yellow outline.

See Also:

getLeadSelectionIndex(), setSelectionInterval(int, int), addSelectionInterval(int, int)

setAnchorSelectionIndex

public void setAnchorSelectionIndex(int index)

Enabled: Set the anchor selection index.

See Also:

getAnchorSelectionIndex()

getLeadSelectionIndex

public int getLeadSelectionIndex()

Enabled: Return the second index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval().

See Also:

getAnchorSelectionIndex(), setSelectionInterval(int, int), addSelectionInterval(int, int)

setLeadSelectionIndex

public void setLeadSelectionIndex(int index)

Enabled: Set the lead selection index.

See Also:

getLeadSelectionIndex()

clearSelection

public void clearSelection()

Enabled: Change the selection to the empty set. If this represents a change to the current selection then notify each ListSelectionListener.

See Also:

addListSelectionListener(javax.swing.event.ListSelectionListener)

isSelectionEmpty

public boolean isSelectionEmpty()

Enabled: Returns true if no indices are selected.

insertIndexInterval

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

Enabled: Insert length indices beginning before/after index. This is typically called to sync the selection model with a corresponding change in the data model.

removeIndexInterval

public void removeIndexInterval(int index0,
                                int index1)

Enabled: 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.

setValueIsAdjusting

public void setValueIsAdjusting(boolean valueIsAdjusting)

Enabled: This property is true if upcoming changes to the value of the model should be considered a single event. For example if the model is being updated in response to a user drag, the value of the valueIsAdjusting property will be set to true when the drag is initiated and be set to false when the drag is finished. This property allows listeners to to update only when a change has been finalized, rather than always handling all of the intermediate values.

Parameters:

valueIsAdjusting - The new value of the property.

See Also:

getValueIsAdjusting()

getValueIsAdjusting

public boolean getValueIsAdjusting()

Enabled: Returns true if the value is undergoing a series of changes.

Returns:

true if the value is currently adjusting

See Also:

setValueIsAdjusting(boolean)

setSelectionMode

public void setSelectionMode(int selectionMode)

Enabled: Set the selection mode. The following selectionMode values are allowed:

• 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.

See Also:

getSelectionMode()

getSelectionMode

public int getSelectionMode()

Enabled: Returns the current selection mode.

Returns:

The value of the selectionMode property.

addListSelectionListener

public void addListSelectionListener(ListSelectionListener x)

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

See Also:

removeListSelectionListener(javax.swing.event.ListSelectionListener), setSelectionInterval(int, int), addSelectionInterval(int, int), removeSelectionInterval(int, int), clearSelection(), insertIndexInterval(int, int, boolean), removeIndexInterval(int, int)

removeListSelectionListener

public void removeListSelectionListener(ListSelectionListener x)

Enabled: Remove a listener from the list that's notified each time a change to the selection occurs.
