com.fr.design.layout.VerticalFlowLayout

所有已实现的接口:

java.awt.LayoutManager, java.io.Serializable

public class VerticalFlowLayout
extends java.lang.Object
implements java.awt.LayoutManager, java.io.Serializable

A vertical flow layout arranges components in a top-to-bottom flow, much like lines of text in a paragraph. Flow layouts are typically used to arrange buttons in a panel. It will arrange buttons top to bottom until no more buttons fit on the same line. Each line is centered.
