Class ScaleFactorLayout

java.lang.Object

ch.randelshofer.gui.ScaleFactorLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2, java.io.Serializable

public class ScaleFactorLayout
extends java.lang.Object
implements java.awt.LayoutManager2, java.io.Serializable

A scale factor layout lays out a container, arranging one single component to fit into its parent while maintaining the aspect of the component. Note: This layout can handle only one single component. The preferred size of the layout is computed by multiplying the preferred size of the component with the scale factor provided by the scale factor constraints. If the layout constraint 'scale to fit' is set to true, the size of the component is adjusted to the current size of the container. If the 'maintain aspect ratio' constraint is set to true, the component keeps its aspect ratio.

Version:

1.3 2006-07-23 Support for pixel aspect ratio added.
1.2 2002-02-06 'Scale to fit' property added.
1.0.2 2000-06-13 Implementation of #layoutContainer improved.
1.0.1 2000-06-12 reworked.
1.0 1999-10-19
