Interface Layouter

All Superinterfaces:

java.io.Serializable, Storable

All Known Implementing Classes:

StandardLayouter

public interface Layouter
extends java.io.Serializable, Storable

A Layouter encapsulates a algorithm to layout a figure. It is passed on to a figure which delegates the layout task to the Layouter's layout method. The Layouter might need access to some information specific to a certain figure in order to layout it out properly. Note: Currently, only the GraphicalCompositeFigure uses such a Layouter to layout its child components.

Method Detail

calculateLayout

java.awt.Rectangle calculateLayout(java.awt.Point origin,
                                   java.awt.Point corner)

layout

java.awt.Rectangle layout(java.awt.Point origin,
                          java.awt.Point corner)

Method which lays out a figure. It is called by the figure if a layout task is to be performed. Implementing classes specify a certain layout algorithm in this method.

Parameters:

origin - start point for the layout

corner - minimum corner point for the layout

setInsets

void setInsets(java.awt.Insets newInsets)

Set the insets for spacing between the figure and its subfigures

Parameters:

newInsets - new spacing dimensions

getInsets

java.awt.Insets getInsets()

Get the insets for spacing between the figure and its subfigures

Returns:

spacing dimensions
