Class VerticalFlowLayout

java.lang.Object
  java.awt.FlowLayout
      org.openbp.swing.layout.VerticalFlowLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.io.Serializable

public class VerticalFlowLayout
extends java.awt.FlowLayout
implements java.io.Serializable

VFlowLayout is similar to FlowLayout except it lays out components vertically. Extends FlowLayout because it mimics much of the behavior of the FlowLayout class, except vertically. An additional feature is that you can specify a fill to edge flag, which causes the VerticalFlowLayout manager to resize all components to expand to the column width Warning: This causes problems when the main panel has less space that it needs and it seems to prohibit multi-column output. Additionally there is a vertical fill flag, which fills the last component to the remaining height of the container.
