Package Summary Overview Summary

### class:ListSelectionModel [NONE]
- All Known Implementing Classes: DefaultListSelectionModel
      public interface ListSelectionModel
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. Since: 1.2 See Also: `DefaultListSelectionModel`

### field:SINGLE_SELECTION [NONE]
- #### SINGLE_SELECTION
      static final int SINGLE_SELECTION
A value for the selectionMode property: select one list index at a time. See Also: `setSelectionMode(int)`, Constant Field Values

### field:SINGLE_INTERVAL_SELECTION [NONE]
- #### SINGLE_INTERVAL_SELECTION
      static final int SINGLE_INTERVAL_SELECTION
A value for the selectionMode property: select one contiguous range of indices at a time. See Also: `setSelectionMode(int)`, Constant Field Values

### field:MULTIPLE_INTERVAL_SELECTION [NONE]
- #### MULTIPLE_INTERVAL_SELECTION
      static final int MULTIPLE_INTERVAL_SELECTION
A value for the selectionMode property: select one or more contiguous ranges of indices at a time. See Also: `setSelectionMode(int)`, Constant Field Values

### method:setSelectionInterval(int, int) [NONE]
- #### setSelectionInterval
      void setSelectionInterval(int index0,
                                int index1)
Changes the selection to be between `index0` and `index1` inclusive. `index0` doesn't have to be less than or equal to `index1`. In `SINGLE_SELECTION` selection mode, only the second index is used. If this represents a change to the current selection, then each `ListSelectionListener` is notified of the change. Parameters: `index0` - one end of the interval. `index1` - other end of the interval See Also: `addListSelectionListener(javax.swing.event.ListSelectionListener)`

### method:addSelectionInterval(int, int) [NONE]
- #### addSelectionInterval
      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. `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. If this represents a change to the current selection, then each `ListSelectionListener` is notified of the change. Parameters: `index0` - one end of the interval. `index1` - other end of the interval See Also: `addListSelectionListener(javax.swing.event.ListSelectionListener)`, `setSelectionInterval(int, int)`

### method:removeSelectionInterval(int, int) [NONE]
- #### removeSelectionInterval
      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. `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`. If this represents a change to the current selection, then each `ListSelectionListener` is notified of the change. Parameters: `index0` - one end of the interval. `index1` - other end of the interval See Also: `addListSelectionListener(javax.swing.event.ListSelectionListener)`

### method:getMinSelectionIndex() [NONE]

### method:getAnchorSelectionIndex() [NONE]
- #### getAnchorSelectionIndex
      int getAnchorSelectionIndex()
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. Returns: the anchor selection index See Also: `getLeadSelectionIndex()`, `setSelectionInterval(int, int)` , `addSelectionInterval(int, int)`

### method:setAnchorSelectionIndex(int) [NONE]

- #### getLeadSelectionIndex
      int getLeadSelectionIndex()
Return the second index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval(). Returns: the lead selection index. See Also: `getAnchorSelectionIndex()`, `setSelectionInterval(int, int)` , `addSelectionInterval(int, int)`

### method:setLeadSelectionIndex(int) [NONE]

                               int length,
                               boolean before)
Insert `length` indices beginning before/after `index`. This is typically called to sync the selection model with a corresponding change in the data model. Parameters: `index` - the beginning of the interval `length` - the length of the interval `before` - if `true`, interval inserts before the `index`, otherwise, interval inserts after the `index`

### method:removeIndexInterval(int, int) [NONE]
- #### removeIndexInterval
      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. Parameters: `index0` - the beginning of the interval `index1` - the end of the interval

### method:setValueIsAdjusting(boolean) [NONE]
- #### setValueIsAdjusting
      void setValueIsAdjusting(boolean valueIsAdjusting)
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 `ListSelectionEvent`s 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 See Also: `getValueIsAdjusting()`, `ListSelectionEvent.getValueIsAdjusting()`

### method:getValueIsAdjusting() [NONE]
- #### getValueIsAdjusting
      boolean getValueIsAdjusting()
Returns `true` if the selection is undergoing a series of changes. Returns: true if the selection is undergoing a series of changes See Also: `setValueIsAdjusting(boolean)`

### method:setSelectionMode(int) [NONE]
- #### setSelectionMode
      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. Parameters: `selectionMode` - the selection mode Throws: `IllegalArgumentException` - if the selection mode isn't one of those allowed See Also: `getSelectionMode()`

### method:getSelectionMode() [NONE]
- #### getSelectionMode
      int getSelectionMode()
