Class VerticalLayouter

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

All Implemented Interfaces:

Layouter

public class VerticalLayouter
extends AbstractLayouter

A layouter which lays out all children of a CompositeFigure in vertical direction. The preferredSize of the figures is used to determine the layout. This may cause some figures to resize.

The VerticalLayouter honors the LAYOUT_INSETS AttributeKey when laying out a Figure.

calculateLayout

public java.awt.geom.Rectangle2D.Double calculateLayout(CompositeFigure layoutable,
                                                        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 layoutable,
                                               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
