0java布局管理器-borderlayout
2安装NetBeans IDE 8.1
0iReport安装java打印
工具/原料
- netbeans
- java
方法/步骤
新建一个java项目。
0java布局管理器-borderlayout
新建一个类，取名jframe2。
打开jframe2.java这个文件，把代码修改为：
public class jframe2 extends javax.swing.JFrame{
public jframe2(){
buju();
}
private void buju(){
}
public static void main(String[] arg){
}
}
定义用到的变量。
在buju这个方法中初始化变量：new 类。
关键代码：
this.getContentPane().setLayout(new java.awt.GridBagLayout());
窗口布局设为GridBagLayout
gridBagConstraints.gridx = 0;布局0列
gridBagConstraints.gridy = 0;布局0行
gridBagConstraints.gridwidth=1; 多少列
gridBagConstraints.gridheight=1; 多少行
gridBagConstraints.weightx=1; 分配水平空间
gridBagConstraints.weighty=1; 分配垂直空间
gridBagConstraints.fill=java.awt.GridBagConstraints.HORIZONTAL填充，水平，垂直，
gridBagConstraints.insets = new java.awt.Insets(5, 5, 5, 5);外侧空间
buju方法中完整代码：
java.awt.GridBagConstraints gridBagConstraints;
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
getContentPane().setLayout(new java.awt.GridBagLayout());
jPanel1.setBorder(javax.swing.BorderFactory.createEtchedBorder());

jPanel1Layout.rowHeights = new int[] {0, 5, 0, 5, 0, 5, 0};
jPanel1.setLayout(jPanel1Layout);
jLabel1.setText("姓名");

gridBagConstraints.fill = java.awt.GridBagConstraints.HORIZONTAL;
jPanel1.add(jTextField9, gridBagConstraints);
jPanel2.setBorder(javax.swing.BorderFactory.createLineBorder(new java.awt.Color(0, 0, 0)));
jPanel2.setOpaque(false);
jPanel2.setPreferredSize(new java.awt.Dimension(80, 100));
gridBagConstraints = new java.awt.GridBagConstraints();
gridBagConstraints.gridx = 16;
gridBagConstraints.gridy = 0;
gridBagConstraints.gridheight = 7;
gridBagConstraints.fill = java.awt.GridBagConstraints.BOTH;
jPanel1.add(jPanel2, gridBagConstraints);
gridBagConstraints = new java.awt.GridBagConstraints();
gridBagConstraints.fill = java.awt.GridBagConstraints.BOTH;
gridBagConstraints.weightx = 1.0;
gridBagConstraints.weighty = 1.0;
gridBagConstraints.insets = new java.awt.Insets(5, 5, 5, 5);
getContentPane().add(jPanel1, gridBagConstraints);
setSize(new java.awt.Dimension(541, 334));
setLocationRelativeTo(null);
添加main方法中代码：
java.awt.EventQueue.invokeLater(new Runnable(){
@Override
public void run(){
new jframe2().setVisible(true);
}
});
运行这个文件jframe2.
