LayerListDialog.LayerListModel (JOSM)

java.lang.Object
- javax.swing.table.AbstractTableModel
- - org.openstreetmap.josm.gui.dialogs.LayerListDialog.LayerListModel

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, javax.swing.table.TableModel, MapView.LayerChangeListener

Enclosing class:

LayerListDialog
```
public final class LayerListDialog.LayerListModel
extends javax.swing.table.AbstractTableModel
implements MapView.LayerChangeListener, java.beans.PropertyChangeListener
```
The layer list model. The model manages a list of layers and provides methods for moving layers up and down, for toggling their visibility, and for activating a layer. The model is a 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 PropertyChangeEvents of every Layer it manages, in particular to the properties Layer.VISIBLE_PROP and Layer.NAME_PROP.
