Class AbstractTreeTableNodeDataRenderer

java.lang.Object
  ca.odell.glazedlists.swing.AbstractTreeTableNodeDataRenderer

All Implemented Interfaces:

TreeTableNodeDataRenderer, TableCellRenderer

public abstract class AbstractTreeTableNodeDataRenderer
extends Object
implements TreeTableNodeDataRenderer

A convenient renderer that eases the implementation of TreeTableNodeDataRenderer by providing convenient access methods to the data within the given TreeNodeData.

Constructor Summary

AbstractTreeTableNodeDataRenderer()

Method Summary

protected boolean	allowsChildren() Returns true if the node is of the type that can have child elements; false otherwise.
protected int	getDepth() Returns the depth of the tree node in the hierarchy.
protected boolean	hasChildren() Returns true if the tree node has child nodes; false otherwise.
protected boolean	isExpanded() Returns true if the node is expanded and its children are thus visible; false if it is collapsed and its children are thus hidden.
void	setTreeNodeData(TreeNodeData treeNodeData) This method will be called before TableCellRenderer.getTableCellRendererComponent(javax.swing.JTable, java.lang.Object, boolean, boolean, int, int) in order to provide hierarchy information about the tree node being rendered.

Method Detail

setTreeNodeData

public final void setTreeNodeData(TreeNodeData treeNodeData)

Description copied from interface: TreeTableNodeDataRenderer

This method will be called before TableCellRenderer.getTableCellRendererComponent(javax.swing.JTable, java.lang.Object, boolean, boolean, int, int) in order to provide hierarchy information about the tree node being rendered. Implementations should store a reference to the given treeNodeData and use it when producing an renderer component.

Specified by:

setTreeNodeData in interface TreeTableNodeDataRenderer

Parameters:

treeNodeData - an object describing hierarchical information about the tree node being rendered

getDepth

protected int getDepth()

Returns the depth of the tree node in the hierarchy.

hasChildren

protected boolean hasChildren()

Returns true if the tree node has child nodes; false otherwise.

allowsChildren

protected boolean allowsChildren()

Returns true if the node is of the type that can have child elements; false otherwise.

isExpanded

protected boolean isExpanded()

Returns true if the node is expanded and its children are thus visible; false if it is collapsed and its children are thus hidden. This argument only has meaning when hasChildren() returns true; otherwise it should be ignored.
