org.jhotdraw.draw.layouter
Class HorizontalLayouter

java.lang.Object
  extended by org.jhotdraw.draw.layouter.AbstractLayouter
      extended by org.jhotdraw.draw.layouter.HorizontalLayouter
All Implemented Interfaces:
Layouter

public class HorizontalLayouter
extends AbstractLayouter

A Layouter which lays out all children of a CompositeFigure in horizontal direction.

The preferred size of the figures is used to determine the layout. This may cause some figures to resize.

The HorizontalLayouter honors the LAYOUT_INSETS and the COMPOSITE_ALIGNMENT AttributeKey when laying out a CompositeFigure.

If COMPOSITE_ALIGNMENT is not set on the composite figure, the layout assigns the same height to all figures.

Method Detail

calculateLayout

public java.awt.geom.Rectangle2D.Double calculateLayout(CompositeFigure compositeFigure,
                                                        java.awt.geom.Point2D.Double anchor,
                                                        java.awt.geom.Point2D.Double lead)
Description copied from interface: Layouter
Calculate the layout for the figure and all its subelements. The layout is not actually performed but just its dimensions are calculated.

anchor - start point for the layout
lead - minimum lead point for the layout

layout

public java.awt.geom.Rectangle2D.Double layout(CompositeFigure compositeFigure,
                                               java.awt.geom.Point2D.Double anchor,
                                               java.awt.geom.Point2D.Double lead)
Description copied from interface: Layouter
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.

anchor - start point for the layout
lead - minimum lead point for the layout
