Method Detail

drawSimpleEdge

protected void drawSimpleEdge(RenderContext<V,E> rc,
                              Layout<V,E> layout,
                              E e)

Draws the edge e, whose endpoints are at (x1,y1) and (x2,y2), on the graphics context g. The Shape provided by the EdgeShapeFunction instance is scaled in the x-direction so that its width is equal to the distance between (x1,y1) and (x2,y2).

Overrides:

drawSimpleEdge in class BasicEdgeRenderer<V,E>

Parameters:

rc - the render context used for rendering the edge

layout - the layout instance which provides the edge's endpoints' coordinates

e - the edge to be drawn

stateChanged

public void stateChanged(ChangeEvent evt)

Specified by:

stateChanged in interface ChangeListener

layoutChanged

public void layoutChanged(LayoutEvent<V,E> evt)

Specified by:

layoutChanged in interface LayoutChangeListener<V,E>
