Class NodeCellRendererPainter

java.lang.Object
  y.view.AbstractCustomNodePainter
      y.view.NodeCellRendererPainter

All Implemented Interfaces:

GenericNodeRealizer.Painter

public class NodeCellRendererPainter
extends AbstractCustomNodePainter
implements GenericNodeRealizer.Painter

A GenericNodeRealizer.Painter implementation that uses NodeCellRenderer instances to render the contents of a node.

NodeCellRenderer

Field Summary

static DataMap

USER_DATA_MAP A convenience DataMap implementation that maps to the userData property of the corresponding NodeRealizer of the Node that is passed to the DataProvider.get(Object) method.

Constructor Summary

NodeCellRendererPainter(NodeCellRenderer ncr, DataProvider dataProvider)
Constructs a NodeCellRendererPainter using the given NodeCellRenderer and the DataProvider that provides access to the "value" that is passed to the renderer for each node being rendered.

Method Summary

DataProvider	getDataProvider() Returns the DataProvider that is used by the getNodeCellRendererComponent(Graph2DView, NodeRealizer,boolean) implementation to query the value for the node being rendered.
NodeCellRenderer	getNodeCellRenderer() Returns the NodeCellRenderer associated with this instance.
protected java.awt.Component	getNodeCellRendererComponent(Graph2DView view, NodeRealizer context, boolean selected) Callback method that determines the component for the rendering for a given Graph2DView and NodeRealizer.
protected void	paintNode(NodeRealizer context, java.awt.Graphics2D graphics, boolean sloppy) Callback method to be overwritten by subclasses called by AbstractCustomNodePainter.paint(NodeRealizer, Graphics2D).
void	paintSloppy(NodeRealizer context, java.awt.Graphics2D graphics) Delegates to AbstractCustomNodePainter.paintNode(NodeRealizer, Graphics2D, boolean) if the node is visible.

Field Detail

USER_DATA_MAP

public static final DataMap USER_DATA_MAP

A convenience DataMap implementation that maps to the userData property of the corresponding NodeRealizer of the Node that is passed to the DataProvider.get(Object) method.

Constructor Detail

NodeCellRendererPainter

public NodeCellRendererPainter(NodeCellRenderer ncr,
                               DataProvider dataProvider)

Constructs a NodeCellRendererPainter using the given NodeCellRenderer and the DataProvider that provides access to the "value" that is passed to the renderer for each node being rendered.

Parameters:

ncr - the renderer used to receive the component to paint on

dataProvider - the instance that provides the value for the renderer for each node

USER_DATA_MAP

Method Detail

getNodeCellRenderer

public NodeCellRenderer getNodeCellRenderer()

Returns the NodeCellRenderer associated with this instance.

Returns:

the current NodeCellRenderer instance associated with this instance.

getDataProvider

public DataProvider getDataProvider()

Returns the DataProvider that is used by the getNodeCellRendererComponent(Graph2DView, NodeRealizer,boolean) implementation to query the value for the node being rendered.

Returns:

the DataProvider that returns for each Node instance the corresponding value object.

paintSloppy

public void paintSloppy(NodeRealizer context,
                        java.awt.Graphics2D graphics)

Description copied from class: AbstractCustomNodePainter

Delegates to AbstractCustomNodePainter.paintNode(NodeRealizer, Graphics2D, boolean) if the node is visible.

Specified by:

paintSloppy in interface GenericNodeRealizer.Painter

Overrides:

paintSloppy in class AbstractCustomNodePainter

Parameters:

context - the context node

graphics - the graphics context to use

getNodeCellRendererComponent

protected java.awt.Component getNodeCellRendererComponent(Graph2DView view,
                                                          NodeRealizer context,
                                                          boolean selected)

Callback method that determines the component for the rendering for a given Graph2DView and NodeRealizer. This implementation queries the NodeCellRenderer associated to this instance.

Parameters:

view - the view where the component will be placed in

context - the node for which the component will be returned

selected - whether or not the component should indicate a selected state.

Returns:

a Component used for the actual rendering of the nodes graphics.

paintNode

protected void paintNode(NodeRealizer context,
                         java.awt.Graphics2D graphics,
                         boolean sloppy)

Description copied from class: AbstractCustomNodePainter

Callback method to be overwritten by subclasses called by AbstractCustomNodePainter.paint(NodeRealizer, Graphics2D). This method is responsible for drawing the actual node only - neither the hotspots, nor the labels, should be painted by this method.

Specified by:

paintNode in class AbstractCustomNodePainter

Parameters:

context - the context node

graphics - the graphics context to use

sloppy - whether to draw the node sloppily
