  javax.swing.AbstractListModel
      net.sourceforge.xwing.AggregatingListModel

All Implemented Interfaces:

ListModel, Serializable

public AggregatingListModel()

Make a new AggregatingListModel.

Method Detail

getSize

public int getSize()

getElementAt

public Object getElementAt(int index)

addListModel

public void addListModel(ListModel src)

Appends the given ListModel onto the end of our list of models. If the added ListModel contains any elements, a ListDataEvent of type INTERVAL_ADDED will be broadcast to any active listeners.

Parameters:

src - the model to add

addListModel

public void addListModel(int index,
                         ListModel src)

Inserts the given ListModel into our list of models. If the added ListModel contains any elements, a ListDataEvent of type INTERVAL_ADDED will be broadcast to any active listeners.

Parameters:

index - Where in our list of models to insert the model.

src - the model to add

addElement

public void addElement(Object element)

Adds a single element to the end of our list of models. All elements added via addElement() are actually added to an internally maintained ListModel. If multiple elements are added in a series, they will all be added to the same internal ListModel. But if another ListModel is added via addListModel(), the next time an element is added a new ListModel will be created and appended to our list of models.

clear

public void clear()

Remove all our contents.
