JAVA_eclipse插件绘制GUI界面过程
安装eclipse插件安装WindowBuilder插件
选择相应的版本install
等待下载安装完成重新启动eclipse
插件的使用
新建项目，选择其他
新建Application Window
生成代码界面和design界面
选择design进行gui界面编辑
例如创建一个简易的计算器4*4界面布局
首先需要是使用布局
其次创建一个文本框TextField
添加一个面板Panel
同时面板布局采用GridLayout,自动排列，往面板添加按钮
左下角设置按钮参数
依次添加全部按钮最后结果
自动生成的代码块如下（部分）
/*** Launch the application.*/public static void main(String[] args) {EventQueue.invokeLater(new Runnable() {public void run() {try {caculatetest window = new caculatetest();window.frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}/*** Create the application.*/public caculatetest() {initialize();}/*** Initialize the contents of the frame.*/private void initialize() {frame = new JFrame();frame.setBounds(100, 100, 522, 504);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);textField = new JTextField();textField.setColumns(10);JPanel panel = new JPanel();GroupLayout groupLayout = new GroupLayout(frame.getContentPane());groupLayout.setHorizontalGroup(groupLayout.createParallelGroup(Alignment.LEADING).addGroup(groupLayout.createSequentialGroup().addContainerGap().addGroup(groupLayout.createParallelGroup(Alignment.LEADING).addComponent(textField, GroupLayout.PREFERRED_SIZE, 484, GroupLayout.PREFERRED_SIZE).addComponent(panel, GroupLayout.PREFERRED_SIZE, 485, GroupLayout.PREFERRED_SIZE)).addContainerGap(13, Short.MAX_VALUE)));groupLayout.setVerticalGroup(groupLayout.createParallelGroup(Alignment.LEADING).addGroup(groupLayout.createSequentialGroup().addContainerGap().addComponent(textField, GroupLayout.PREFERRED_SIZE, 82, GroupLayout.PREFERRED_SIZE).addPreferredGap(ComponentPlacement.RELATED).addComponent(panel, GroupLayout.PREFERRED_SIZE, 349, GroupLayout.PREFERRED_SIZE).addContainerGap(20, Short.MAX_VALUE)));panel.setLayout(new GridLayout(4, 4, 0, 0));btnNewButton_1 = new JButton("+");btnNewButton_1.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_1);btnNewButton = new JButton("-");btnNewButton.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton);btnNewButton_2 = new JButton("x");btnNewButton_2.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_2);btnNewButton_3 = new JButton("/");btnNewButton_3.setEnabled(true);btnNewButton_3.setFont(new Font("Dialog", Font.PLAIN, 17));panel.add(btnNewButton_3);btnNewButton_4 = new JButton("1");btnNewButton_4.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_4);btnNewButton_5 = new JButton("2");btnNewButton_5.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_5);btnNewButton_6 = new JButton("3");btnNewButton_6.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_6);btnNewButton_7 = new JButton("0");btnNewButton_7.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_7);btnNewButton_8 = new JButton("4");btnNewButton_8.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_8);btnNewButton_9 = new JButton("5");btnNewButton_9.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_9);btnNewButton_10 = new JButton("6");btnNewButton_10.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_10);btnNewButton_11 = new JButton("c");btnNewButton_11.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_11);btnNewButton_12 = new JButton("7");btnNewButton_12.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_12);btnNewButton_13 = new JButton("8");btnNewButton_13.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_13);btnNewButton_14 = new JButton("9");btnNewButton_14.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_14);btnNewButton_15 = new JButton("=");btnNewButton_15.setFont(new Font("宋体", Font.PLAIN, 17));panel.add(btnNewButton_15);frame.getContentPane().setLayout(groupLayout);
