Class HorizontalLayouter

java.lang.Object
  org.jhotdraw.draw.layouter.AbstractLayouter
      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.

calculateLayout

public java.awt.geom.Rectangle2D.Double calculateLayout(CompositeFigure compositeFigure,
                                                        java.awt.geom.Point2D.Double anchor,

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
