javax.swing.DefaultListSelectionModel — clojure-interop/javax.swing 1.0.5

Default data model for list selections.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

->default-list-selection-model clj

(->default-list-selection-model)

Constructor.

add-list-selection-listener clj

(add-list-selection-listener this l)

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

l - the ListSelectionListener - javax.swing.event.ListSelectionListener

add-selection-interval clj

(add-selection-interval this index-0 index-1)

Changes the selection to be the set union of the current selection and the indices between index0 and index1 inclusive.

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 it.

If this represents a change to the current selection, then each ListSelectionListener is notified of the change. Note that index0 doesn't have to be less than or equal to index1.

If either index is -1, this method does nothing and returns without exception. Otherwise, if either index is less than -1, an IndexOutOfBoundsException is thrown.

index-0 - one end of the interval. - int index-1 - other end of the interval - int

throws: java.lang.IndexOutOfBoundsException - if either index is less than -1 (and neither index is -1)

clear-selection clj

(clear-selection this)

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

clone clj

(clone this)

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

returns: a clone of this instance. - java.lang.Object

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

get-anchor-selection-index clj

(get-anchor-selection-index this)

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: int

get-lead-selection-index clj

(get-lead-selection-index this)

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

returns: int

get-list-selection-listeners clj

(get-list-selection-listeners this)

Returns an array of all the list selection listeners registered on this DefaultListSelectionModel.

returns: all of this model's ListSelectionListeners or an empty array if no list selection listeners are currently registered - javax.swing.event.ListSelectionListener[]

get-listeners clj

(get-listeners this listener-type)

Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultListSelectionModel instance m for its list selection listeners with the following code:

ListSelectionListener[] lsls = (ListSelectionListener[])(m.getListeners(ListSelectionListener.class));

If no such listeners exist, this method returns an empty array.

listener-type - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener - java.lang.Class

returns: an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added - <T extends java.util.EventListener> T[]

throws: java.lang.ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener

get-max-selection-index clj

(get-max-selection-index this)

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

returns: int

get-min-selection-index clj

(get-min-selection-index this)

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

returns: int

get-selection-mode clj

(get-selection-mode this)

Returns the current selection mode.

returns: the current selection mode - int

get-value-is-adjusting? clj

(get-value-is-adjusting? this)

Returns true if the selection is undergoing a series of changes.

returns: true if the selection is undergoing a series of changes - boolean

insert-index-interval clj

(insert-index-interval this index length before)

Insert length indices beginning before/after index. If the value at index is itself selected and the selection mode is not SINGLE_SELECTION, set all of the newly inserted items as selected. Otherwise leave them unselected. This method is typically called to sync the selection model with a corresponding change in the data model.

index - int length - int before - boolean

lead-anchor-notification-enabled? clj

(lead-anchor-notification-enabled? this)

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 narrowing 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.

Note: It is possible for the lead or anchor to be changed without a change to the selection. Notification of these changes is often important, such as when the new lead or anchor needs to be updated in the view. Therefore, caution is urged when changing the default value.

returns: the value of the leadAnchorNotificationEnabled flag - boolean

move-lead-selection-index clj

(move-lead-selection-index this lead-index)

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

lead-index - the new lead selection index - int

remove-index-interval clj

(remove-index-interval this index-0 index-1)

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.

index-0 - int index-1 - int

remove-list-selection-listener clj

(remove-list-selection-listener this l)

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

l - the ListSelectionListener - javax.swing.event.ListSelectionListener

remove-selection-interval clj

(remove-selection-interval this index-0 index-1)

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.

If either index is -1, this method does nothing and returns without exception. Otherwise, if either index is less than -1, an IndexOutOfBoundsException is thrown.

index-0 - one end of the interval - int index-1 - other end of the interval - int

throws: java.lang.IndexOutOfBoundsException - if either index is less than -1 (and neither index is -1)

selected-index? clj

(selected-index? this index)

Returns true if the specified index is selected.

index - int

returns: boolean

selection-empty? clj

(selection-empty? this)

Returns true if no indices are selected.

returns: boolean

set-anchor-selection-index clj

(set-anchor-selection-index this anchor-index)

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

anchor-index - int

set-lead-anchor-notification-enabled clj

(set-lead-anchor-notification-enabled this flag)

Sets the value of the leadAnchorNotificationEnabled flag.

flag - boolean

set-lead-selection-index clj

(set-lead-selection-index this lead-index)

Sets 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 deselecting 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.

lead-index - int

set-selection-interval clj

(set-selection-interval this index-0 index-1)

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.

If either index is -1, this method does nothing and returns without exception. Otherwise, if either index is less than -1, an IndexOutOfBoundsException is thrown.

index-0 - one end of the interval. - int index-1 - other end of the interval - int

throws: java.lang.IndexOutOfBoundsException - if either index is less than -1 (and neither index is -1)

set-selection-mode clj

(set-selection-mode this selection-mode)

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.

selection-mode - int

throws: java.lang.IllegalArgumentException - if the selection mode isn't one of those allowed

set-value-is-adjusting clj

(set-value-is-adjusting this is-adjusting)

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.

is-adjusting - the new value of the property - boolean

to-string clj

(to-string this)

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

returns: a String representation of this object - java.lang.String
