Method Detail

getGroupAt

public Object getGroupAt(int index)

Description copied from interface: GroupableListModel

Returns the group of the element at the specified index. Note that the order of groups is controlled by first getGroups() then getGroupAt(int).

Specified by:

getGroupAt in interface GroupableListModel

Parameters:

index - the index of element

Returns:

the group for the specified index.

GroupableListModel.getGroups()

getGroups

public Object[] getGroups()

Description copied from interface: GroupableListModel

Returns all groups, which control the order of appearance. Besides, if getGroupAt(int) returns a value that doesn't exist in the groups, the value will be arranged after the array.

Specified by:

getGroups in interface GroupableListModel

Returns:

an array of groups in the order of appearance.

GroupableListModel.getGroupAt(int)

addListGroupChangeListener

public void addListGroupChangeListener(ListGroupChangeListener l)

Adds a listener to the list that's notified each time a change to the data model occurs.

Specified by:

addListGroupChangeListener in interface GroupableListModel

Parameters:

l - the ListGroupChangeListener to be added

removeListGroupChangeListener

public void removeListGroupChangeListener(ListGroupChangeListener l)

Removes a listener from the list that's notified each time a change to the data model occurs.

Specified by:

removeListGroupChangeListener in interface GroupableListModel

Parameters:

l - the ListGroupChangeListener to be removed

getListGroupChangeListeners

public ListGroupChangeListener[] getListGroupChangeListeners()

Returns an array of all the list group change listeners registered on this DefaultGroupableListModel.

Returns:

all of this model's ListGroupChangeListeners, or an empty array if no list data listeners are currently registered

fireGroupChanged

protected void fireGroupChanged(Object source)

AbstractListModel subclasses must call this method after the group for any of the item is changed.

Parameters:

source - the ListModel that changed, typically "this"
