This interface represents the current state of the
selection for any of the components that display a
list of values with stable indices.
This interface represents the current state of the selection for any of the components that display a list of values with stable indices. The selection is modeled as a set of intervals, each interval represents a contiguous range of selected list elements. The methods for modifying the set of selected intervals all take a pair of indices, index0 and index1, that represent a closed interval, i.e. the interval includes both index0 and index1.
public 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.
Changes the selection to be the set union of the current selection
and the indices between index0 and index1 inclusive.
index0 doesn't have to be less than or equal to index1.
In SINGLE_SELECTION selection mode, this is equivalent
to calling setSelectionInterval, and only the second index
is used. In SINGLE_INTERVAL_SELECTION selection mode, this
method behaves like setSelectionInterval, unless the given
interval is immediately adjacent to or overlaps the existing selection,
and can therefore be used to grow the selection.
public void
insertIndexInterval
(int index, int length, boolean before)
Insert length indices beginning before/after index.
Insert length indices beginning before/after index. This is typically called to sync the selection model with a corresponding change in the data model.
public boolean
isSelectedIndex
(int index)
Returns true if the specified index is selected.
public boolean
isSelectionEmpty
()
Returns true if no indices are selected.
public void
removeIndexInterval
(int index0, int index1)
Remove the indices in the interval index0,index1 (inclusive) from
the selection model.
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.
public 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.
Changes the selection to be the set difference of the current selection
and the indices between index0 and index1 inclusive.
index0 doesn't have to be less than or equal to index1.
In SINGLE_INTERVAL_SELECTION selection mode, if the removal
would produce two disjoint selections, the removal is extended through
the greater end of the selection. For example, if the selection is
0-10 and you supply indices 5,6 (in any order) the
resulting selection is 0-4.
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.
public void
setValueIsAdjusting
(boolean valueIsAdjusting)
Sets the valueIsAdjusting property, which indicates whether
or not upcoming selection changes should be considered part of a single
change.
Sets the valueIsAdjusting property, which indicates whether
or not upcoming selection changes should be considered part of a single
change. The value of this property is used to initialize the
valueIsAdjusting property of the ListSelectionEvents that
are generated.
For example, if the selection is being updated in response to a user
drag, this property can be set to true when the drag is initiated
and set to false when the drag is finished. During the drag,
listeners receive events with a valueIsAdjusting property
set to true. At the end of the drag, when the change is
finalized, listeners receive an event with the value set to false.
Listeners can use this pattern if they wish to update only when a change
has been finalized.
Setting this property to true begins a series of changes that
is to be considered part of a single change. When the property is changed
back to false, an event is sent out characterizing the entire
selection change (if there was one), with the event's
valueIsAdjusting property set to false.
Parameters: - valueIsAdjusting - the new value of the property
