Constructor Detail

BasicNodeRenderer

public BasicNodeRenderer(GraphController controller)

Create a renderer which renders nodes square and orange.

BasicNodeRenderer

public BasicNodeRenderer(GraphController controller,
                         java.awt.Shape nodeShape,
                         java.awt.Shape compositeShape,
                         java.awt.Paint nodeFill,
                         java.awt.Paint compositeFill,
                         double compositeScale)

Create a renderer which renders nodes using the given shape and fill paint. The given shape must be cloneable.

Method Detail

getCompositeFill

public java.awt.Paint getCompositeFill()

Return the fill that composites are painted with.

getCompositeScale

public double getCompositeScale()

Return the scaling factor for the composite nodes

See Also:

setCompositeScale(double)

getCompositeShape

public java.awt.Shape getCompositeShape()

Return the shape that composites are rendered in.

getGraphController

public GraphController getGraphController()

Return the graph controller.

getNodeFill

render

public Figure render(java.lang.Object node)

Return the rendered visual representation of this node.

Specified by:

render in interface NodeRenderer

Parameters:

node - The node to render.

Returns:

The persistent object that is drawn on the screen.

setCompositeFill

public void setCompositeFill(java.awt.Paint p)

Set the fill to paint the composites with.

setCompositeScale
