Constructor Detail

PortRenderer

public PortRenderer()

Constructs a renderer that may be used to render ports.

Method Detail

getRendererComponent

public java.awt.Component getRendererComponent(JGraph graph,
                                      CellView view,
                                      boolean sel,
                                      boolean focus,
                                      boolean preview)

Configure and return the renderer based on the passed in components. The value is typically set from messaging the graph with convertValueToString.

Specified by:

getRendererComponent in interface CellViewRenderer

Parameters:

graph - the graph that that defines the rendering context.

view - the cell view that should be rendered.

sel - whether the object is selected.

focus - whether the object has the focus.

preview - whether we are drawing a preview.

Returns:

the component used to render the value.

paint

public void paint(java.awt.Graphics g)

Paint the renderer. Overrides superclass paint to add specific painting. Note: The preview flag is interpreted as "highlight" in this context. (This is used to highlight the port if the mouse is over it.)

Overrides:

paint in class javax.swing.JComponent

public void validate()

Overridden for performance reasons. See the Implementation Note for more information.

Overrides:

validate in class java.awt.Container
