体验Java SE 6 中的 GroupLayout

esls — Mon, 18 Dec 2006 06:56:00 GMT

Java SE 6 中包含一个新�?GroupLayout �Q�从GroupLayout的单词意思来看，它是以Group(�l?为单位来��理布局�Q�也��是把多个组�?如：JLable、JButton)按区域划分到不同的Group(�l?,再根据各个Group(�l?相对于水�q��u(Horizontal)和垂直��u(Vertical)的排列方式来��理。下面我们针对这样一个界面看看它的用法：

首先划分�l�：

1、按水��^(Horizontal)方向划分�Q?br />
hpg1 : JLabel 所在组(只有一个组件可以不用分�l?
hpg2a : 左边两个JCheckBox�q��于水�q��u(Horizontal)排列,构成一个ParallelGroup
hpg2b : 双��两个JChecKBox�q��于水�q��u(Horizontal)排列,构成一个ParallelGroup
hpg2H : hpg2a �?hpg2b 两个�l�沿着水��^�?Horizontal)��序排列�Q�构成一个SequentialGroup
hpg2 : JTextBox和组hpg2H �q��于水�q��u(Horizontal)排列,构成一个ParallelGroup
hpg3 : 两个JTextBox�q��于水�q��u(Horizontal)排列,构成一个ParallelGroup

另外JLabel 、hpg2、hpg3 沿着水��^�?Horizontal)��序排列�Q�构成一个SequentialGroup

2、按垂直(Vertical)方向划分�Q?br />

vpg1 : JLabel、JTextBox 、JButton(Find)�q��于垂直��u(Vertical)排列,构成一个ParallelGroup
vpg2 : 上边两个JChecKBox、JButton(Cancel)�q��于垂直��u(Vertical)排列,构成一个ParallelGroup
vpg3 : 下边两个JChecKBox�q��于垂直��u(Vertical)排列,构成一个ParallelGroup

另外vpg1、vpg2、vpg3 三个�l�沿着垂直�?Vertical)��序排列�Q�构成一个SequentialGroup

3、编码：水��^和垂直两个方向我们都必须讑֮�,实现�Ҏ��详见�E�序�?br />addComponent�Q�向Group里添加组�Ӟ��如JLabel、JTextBox
addGroup : 向Group里添加组

    layout.linkSize(SwingConstants.HORIZONTAL,new Component[] { findButton, cancelButton });
    //layout.linkSize(SwingConstants.HORIZONTAL,new Component[] { caseCheckBox, wholeCheckBox, wrapCheckBox, backCheckBox});

使用 Ant �?UltraEdit-32 构徏 Java 开发环�?/p>

1、本�Ҏ��针对Java语言的初学者�?br />2、徏议的软�g包：
   Windows XP
   jdk1.5.0_07      (安装在d:\)
   apache-ant-1.6.5 (安装在d:\)
   UtraEdit-32 12.20b中文�?br />3、环境变量设�?br />   鼠标右键点击"我的电脑"->属�?>高��->环境变量
    ->用户变量->新徏->变量名：JAVA_HOME 变量��|��d:\jdk1.5.0_07
                      变量名：ANT_HOME 变量��|��d:\apache-ant-1.6.5
                      变量名：PATH      变量��|��%PATH%;%ANT_HOME%\bin
4、运行UtraEdit-32
5、如果没�?高��"菜单�Q�鼠标右键点击菜单栏 -> Advanced
6、高�U?>工具配置->插入->菜单��名�U�ͼ�Ant工具
                             命��o行：ant -f %Pbuild.xml %modify%
                            ->输出->命��o输出(DOS命��o输出)->输出到列表框
7�?高��"菜单的最下面��有了一�?Ant工具"菜单��，到此开发环境已�l�搭建完毕，可以�l�习�~�程了�?br />8、徏立文件夹d:\myapp �?d:\myapp\src
9、用UtraEdit-32�~�辑Test.java文�g�Q�保存到d:\myapp\src,内容如下�Q?br />    package test;
    import javax.swing.*;
    public class Test{
      public static void main(String[] args){
        //System.out.println("Hello,Ant & UltraEdit-32!");
        JOptionPane.showMessageDialog(null,"Hello,Ant & UltraEdit-32!");
      }
    }
10、用UtraEdit-32�~�辑build.xml文�g�Q�保存到d:\myapp\src,内容如下�Q?br />























11、选择"Ant工具"菜单��?或按ctrl+shift+0),在出现的对话框中�Q?br />    输入run到文字的最�?如：ant -f D:\java\myApp\test\src\build.xml run)�Q?br />    选择"��定"�?br />12、注意：在用"Ant工具"菜单��Ҏ��Q�保持以上文件至��有一个在�~�辑状态，否则路径可能不对�?br />
