关于JAVA AnchorLayout布局不值一提的发现

昨天看了AnchorLayout布局，发现它是一个很不错的布局，但是遇到个问题，看代码先。

import com.cloudgarden.layout.AnchorConstraint;import com.cloudgarden.layout.AnchorLayout;import javax.swing.JPanel;import javax.swing.WindowConstants;import javax.swing.SwingUtilities;public class NewJFrame extends javax.swing.JFrame { private JPanel jPanel4; private JPanel jPanel1;

 /** * Auto-generated main method to display this JFrame */ public static void main(String[] args) {  SwingUtilities.invokeLater(new Runnable() {   public void run() {    NewJFrame inst = new NewJFrame();    inst.setLocationRelativeTo(null);    inst.setVisible(true);   }  }); }  public NewJFrame() {  super();  initGUI(); }  private void initGUI() {  try {   AnchorLayout thisLayout = new AnchorLayout();   getContentPane().setLayout(thisLayout);   setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);   {    jPanel1 = new JPanel();    getContentPane().add(jPanel1, new AnchorConstraint(1, 905, 1001, 0, AnchorConstraint.ANCHOR_REL, AnchorConstraint.ANCHOR_REL, AnchorConstraint.ANCHOR_REL, AnchorConstraint.ANCHOR_REL));    jPanel1.setPreferredSize(new java.awt.Dimension(557, 330));   }   pack();   this.setSize(400, 400);  } catch (Exception e) {      //add your error handling code here   e.printStackTrace();  } }

}

 

红色部分数字为编辑区域的千分比，后面的 AnchorConstraint.ANCHOR_REL、AnchorConstraint.ANCHOR_ABS、AnchorConstraint.ANCHOR_NONE分别为相对、绝对、没有（这个是猜的）位置，分别对应前面的数字。
