charvax.swing.DefaultListSelectionModel
- ListSelectionModel
public class DefaultListSelectionModel
extends java.lang.Object
Default data model for list selections.
protected ArrayList | _listeners - The list of listeners.
|
protected TreeSet | _selection - The set of selected indices.
|
void | addListSelectionListener(ListSelectionListener l_) - Add a listener to the list that is notified each time a change to
the selection occurs.
|
void | addSelectionInterval(int index0, int index1) - Change the selection to be the set union between the current
selection and the indices between index0 and index1 inclusive.
|
void | clearSelection() - Change the selection to be the empty set.
|
protected void | fireValueChanged(int firstindex_, int lastindex_) - Notify the listeners that the selection has changed.
|
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.
|
void | insertIndexInterval(int index, int length, boolean before) - Insert length indices beginning before/after index, without
notifying the ListSelectionListeners.
|
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, without notifying the ListSelectionListeners.
|
void | removeListSelectionListener(ListSelectionListener l_) - Remove a listener from the list.
|
void | removeSelectionInterval(int index0, int index1) - Change the selection to be the set difference between the current
selection and the indices between index0 and index1 inclusive.
|
void | setSelectionInterval(int index0, int index1) - Change the selection to be between index0 and index1 inclusive.
|
void | setSelectionMode(int mode_) - Set the selection mode.

protected TreeSet _selection
The set of selected indices.
DefaultListSelectionModel
public DefaultListSelectionModel()
addSelectionInterval
public void addSelectionInterval(int index0,
int index1)
Change the selection to be the set union between 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 does not have to be less
than or equal to index1.
- addSelectionInterval in interface ListSelectionModel
clearSelection
public void clearSelection()
Change the selection to be the empty set. If this represents a change
to the selection then notify each ListSelectionListener.
- clearSelection in interface ListSelectionModel
fireValueChanged
protected void fireValueChanged(int firstindex_,
int lastindex_)
Notify the listeners that the selection has changed.
firstindex_
- The first index in the intervallastindex_
- The last index in the interval.
insertIndexInterval
public void insertIndexInterval(int index,
int length,
boolean before)
Insert length indices beginning before/after index, without
notifying the ListSelectionListeners. This
is typically called to sync the selection model with a
corresponding change in the data model.
- insertIndexInterval in interface ListSelectionModel
removeIndexInterval
public void removeIndexInterval(int index0,
int index1)
Remove the indices in the interval index0,index1 (inclusive)
from the selection model, without notifying the ListSelectionListeners.
This is typically called to sync the
selection model with a corresponding change in the data model.
- removeIndexInterval in interface ListSelectionModel
removeSelectionInterval
public void removeSelectionInterval(int index0,
int index1)
Change the selection to be the set difference between 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 does not have to be less
than or equal to index1.
- removeSelectionInterval in interface ListSelectionModel
setSelectionInterval
public void setSelectionInterval(int index0,
int index1)
Change the selection to be between index0 and index1 inclusive.
If this represents a change to the selection, then notify each
ListSelectionListener. Note that index0 doesn't have to be less than or
equal to index1.
- setSelectionInterval in interface ListSelectionModel
setSelectionMode
public void setSelectionMode(int mode_)
Set the selection mode. The following modes are allowed:
- SINGLE_SELECTION. Only one list index can be selected at a time.
- SINGLE_INTERVAL_SELECTION. One contiguous index interval can be set
at at time.
