JLabel Label = new JLabel("用户:",JLabel.CENTER);

JScrollPane scrollpane = new JScrollPane(table);

Box box = Box.createHorizontalBox();

box.add(Button2);

add(table,BorderLayout.NORTH);
add(Label,BorderLayout.CENTER);
add(box,BorderLayout.SOUTH);
}
public static void main(String []args){
test Test = new test();
Test.setVisible(true);

两个按钮怎么放到中间啊,求教

Answer 1

你可以将容器的整体布局设置为FlowLayout，然后在FlowLayout中添加一个Box布局，Box再添加3个部分，分别是表格、标签和按钮，两个按钮可以在用一个再新建一个Box对象并添加进去，下面是代码：

import javax.swing.*;
import java.awt.*;
public class test extends JFrame{
public test()
{
setSize(300,200);
setLocationRelativeTo(null); //使窗体居中显示
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new FlowLayout());
setTitle("用户信息");

String str[] = {"属性","信息"};
Object str2[][]={{"姓名",""},{"职工号",""},{"身份证号",""},{"性别",""},{"出生年月",""}};
JTable table = new JTable(str2,str);
JButton Button1 = new JButton("修改信息");
JButton Button2 = new JButton("修改密码");
JLabel Label = new JLabel("用户:",JLabel.CENTER);
JScrollPane scrollpane = new JScrollPane(table);

Box box = Box.createVerticalBox();
Box buttonBox = Box.createHorizontalBox();

buttonBox.add(Button1);
buttonBox.add(Button2);

box.add(table);
box.add(Label);
box.add(buttonBox);

add(box);
}
public static void main(String []args)
{
test Test = new test();
Test.setVisible(true);
}
}
