Method Detail

getRendererComponent

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. We recommend you check the value's class and throw an illegal argument exception if it's not correct.

Parameters:

graph - the graph that that defines the rendering context.

view - the 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.
