public class IlvMapLegend
extends JPanel
implements TreeModelListener

Class for displaying a legend. A legend is a visual summary of the layers a map displays. This class is designed to work with a IlvMapLayerTreeModel which holds the IlvMapLayer displayed by this legend. The items of the legend can be displayed in categories. The control of the categories, the text displayed and the grouping of legend items is made from the values found in the IlvMapStyle of each IlvMapLayer displayed. The values of the properties IlvMapStyle.CATEGORY and IlvMapStyle.LEGEND_GROUP controls the category in which the layer will fit, the aggregation of layers and the text displayed in the legend.

Since:

JViews 7.5

Constructor Detail

IlvMapLegend

public IlvMapLegend()

Constructs an IlvMapLegend.

Method Detail

setView

public void setView(IlvManagerView v)

Sets the IlvManagerView seen by this legend. The list of layers displayed by the legend is found on the IlvMapLayerTreeModel of the IlvMapLayerTreeProperty attached to the manager associated with the view.

Parameters:

v - The IlvManagerView to attach.

getView

public IlvManagerView getView()

Retrieves the view attached to this legend.

Returns:

The IlvManagerView attached to this legend.

treeNodesChanged

public void treeNodesChanged(TreeModelEvent e)

Invoked after a node (or a set of siblings) has changed in some way. Default implementation does nothing.

Specified by:

treeNodesChanged in interface TreeModelListener

See Also:

TreeModelListener.treeNodesChanged(javax.swing.event.TreeModelEvent)

treeNodesInserted

public void treeNodesInserted(TreeModelEvent e)

Invoked after layers have been inserted into the tree.

Specified by:

treeNodesInserted in interface TreeModelListener

See Also:

TreeModelListener.treeNodesInserted(javax.swing.event.TreeModelEvent)

treeNodesRemoved

public void treeNodesRemoved(TreeModelEvent e)

Invoked after layers have been removed from the tree.

Specified by:

treeNodesRemoved in interface TreeModelListener

See Also:

TreeModelListener.treeNodesRemoved(javax.swing.event.TreeModelEvent)

treeStructureChanged

public void treeStructureChanged(TreeModelEvent e)

Invoked after the tree has drastically changed structure from a given node down.

Specified by:

treeStructureChanged in interface TreeModelListener

See Also:

Default implementation does nothing.

getDescription

public String getDescription(IlvMapLayer layer)

Returns the description of the layer. The description of the layer is the text that will be shown in the legend. This default implementation return the name of the layer.

Parameters:

layer - The layer whose description is returned.

Returns:

The description of the layer.

isDoRasters

public boolean isDoRasters()

Returns true if raster layers should be shown in legend.

Returns:

true if raster layers should be shown in legend.

setDoRasters

public void setDoRasters(boolean dor)

Displays or hide raster layers in the legend. Default is to hide rasters. Showing rasters in the legend may cause performance issues, as JViews will update the raster preview image each time the image itself changes.

Parameters:

dor - indicates whether raster layers should be shown in legend.
