public class LayerTreeNode
extends BasicTreeNode

A TreeNode that represents a Layer.

The node's selection state is synchronized with its Layer's enabled state. isSelected() returns whether the node's Layer is enabled. Calling setSelected(boolean) specifies both the the node's selection state, and whether its Layer should be enabled for rendering and selection.

layer

protected Layer layer

Indicates the Layer this node represents. Initialized to a non-null value during construction.

Constructor Detail

LayerTreeNode

public LayerTreeNode(Layer layer)

Creates a new LayerTreeNode from the specified layer. The node's name is set to the layer's name.

Parameters:

layer - the Layer this node represents.

Throws:

java.lang.IllegalArgumentException - if the layer is null.

Method Detail

initialize

protected void initialize()

Initializes this node's image source.

isSelected

public boolean isSelected()

Indicates whether this node's Layer is enabled for rendering and selection.

Specified by:

isSelected in interface TreeNode

Overrides:

isSelected in class BasicTreeNode

Returns:

true if the Layer is enabled, otherwise false.

See Also:

TreeNode.setSelected(boolean), TreeNode.isTreeSelected()

setSelected

public void setSelected(boolean selected)

Specifies whether this node's Layer is enabled for rendering and selection. This sets both the node's selection state and its Layer's enabled state.

Specified by:

setSelected in interface TreeNode

Overrides:

setSelected in class BasicTreeNode

Parameters:

selected - true to enable the Layer, otherwise false.
