Interface ListSelectionModel

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.

          A value for the selectionMode property: select one or more contiguous ranges of indices at a time.

static int SINGLE_INTERVAL_SELECTION
          A value for the selectionMode property: select one contiguous range of indices at a time.

Method Detail

setSelectionInterval

void setSelectionInterval(int index0,
                          int index1)

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

void addSelectionInterval(int index0,
                          int index1)

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

void removeSelectionInterval(int index0,
                             int index1)

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
See Also:: addListSelectionListener(javax.swing.event.ListSelectionListener)

getMinSelectionIndex

int getMinSelectionIndex()

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

getMaxSelectionIndex

int getMaxSelectionIndex()

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

isSelectedIndex

boolean isSelectedIndex(int index)

Returns true if the specified index is selected.

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.

See Also:: getLeadSelectionIndex(), setSelectionInterval(int, int), addSelectionInterval(int, int)

setAnchorSelectionIndex

void setAnchorSelectionIndex(int index)

Set the anchor selection index.

See Also:: getAnchorSelectionIndex()

getLeadSelectionIndex

int getLeadSelectionIndex()

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

void setLeadSelectionIndex(int index)

Set the lead selection index.

See Also:: getLeadSelectionIndex()

clearSelection

void clearSelection()

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

boolean isSelectionEmpty()

Returns true if no indices are selected.

insertIndexInterval

void insertIndexInterval(int index,
                         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.

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.

setValueIsAdjusting

void setValueIsAdjusting(boolean valueIsAdjusting)

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

boolean getValueIsAdjusting()

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

Returns:: true if the value is currently adjusting
See Also:: setValueIsAdjusting(boolean)

setSelectionMode

void setSelectionMode(int selectionMode)

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

int getSelectionMode()

Returns the current selection mode.

Returns:: The value of the selectionMode property.
See Also:: setSelectionMode(int)

addListSelectionListener

removeListSelectionListener

void removeListSelectionListener(ListSelectionListener x)

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

Parameters:: x - the ListSelectionListener

Contenu

Le contenu de cette page provient du site de Sun, et est généré depuis un cache sur l'infobrol après certains traitements automatisés. La présentation peut donc différer du document original, mais le contenu aussi. Vous pouvez utiliser ce bouton pour afficher la page originale du site de Sun :

Quels sont les motivations de cette démarche?

Maintenir les pages en cache sur différents sites peut offrir plus de disponibilité.

Chaque page est indexée dans la base de donnée, ce qui permet de retrouver facilement les informations, au moyen des sommaires, du moteur de recherche interne, etc.

Des facilités sont mises en place pour que les membres de l'infobrol puissent effectuer des traductions en français des différents documents. Ceci devrait permettre aux débutants en programmation Java de consulter les API en français s'ils maîtrisent moins bien la langue de Shakespeare. Dans le cas où une traduction a été soumise, elle est disponible au moyen d'un lien en bas de page. Si la traduction a été validée, la page s'affiche par défaut en français, et un lien en bas de page permet d'atteindre la version en anglais.

Le code sur l'infobrol est automatiquement coloré selon la syntaxe, et les différents mots clés sont transformés en liens pour accéder rapidement aux informations.

Vous avez la possibilité de partager vos expériences en proposant vos propres extraits de code en utilisant le bouton "ajouter un commentaire" en bas de page. Si vous visitez simplement l'infobrol, vous avez déjà accès à cette fonction, mais si vous étes membre du brol, vous pouvez en plus utiliser des boutons supplémentaires de mise en forme, dont la coloration automatique de vos extraits de codes.
