public static final class LayerListDialog.LayerListModel extends javax.swing.table.AbstractTableModel implements LayerManager.LayerChangeListener, MainLayerManager.ActiveLayerChangeListener, java.beans.PropertyChangeListener
TableModel
and it provides a ListSelectionModel
. It expects
to be configured with a DefaultListSelectionModel
. The selection model is used
to update the selection state of views depending on messages sent to the model.
The model manages a list of LayerListDialog.LayerListModelListener
which are mainly notified if
the model requires views to make a specific list entry visible.
It also listens to PropertyChangeEvent
s of every Layer
it manages, in particular to
the properties Layer.VISIBLE_PROP
and Layer.NAME_PROP
