可以使用Java Swing中的GridLayout和GridBagLayout布局来实现广西医科大学研究生教务管理系统登录界面。以下是一个简单的示例代码:
```
import javax.swing.*;
import java.awt.*;
public class LoginGUI extends JFrame {
private JLabel identityLabel, usernameLabel, passwordLabel, captchaLabel;
private JComboBox identityComboBox;
private JTextField usernameTextField, captchaTextField;
private JPasswordField passwordField;
private JButton loginButton;
public LoginGUI() {
setTitle("广西医科大学研究生教务管理系统");
setSize(400, 250);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// 创建布局管理器
JPanel panel = new JPanel(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
// 登录身份
identityLabel = new JLabel("登录身份:");
gbc.gridx = 0;
gbc.gridy = 0;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(10, 10, 0, 0);
panel.add(identityLabel, gbc);
String[] identities = {"教师版", "学生版", "评阅专家版", "校外双盲评阅版", "直属版", "病区版"};
identityComboBox = new JComboBox(identities);
gbc.gridx = 1;
gbc.gridy = 0;
gbc.insets = new Insets(10, 10, 0, 10);
panel.add(identityComboBox, gbc);
// 用户名
usernameLabel = new JLabel("用户名:");
gbc.gridx = 0;
gbc.gridy = 1;
gbc.insets = new Insets(10, 10, 0, 0);
panel.add(usernameLabel, gbc);
usernameTextField = new JTextField(20);
gbc.gridx = 1;
gbc.gridy = 1;
gbc.insets = new Insets(10, 10, 0, 10);
panel.add(usernameTextField, gbc);
// 密码
passwordLabel = new JLabel("密码:");
gbc.gridx = 0;
gbc.gridy = 2;
gbc.insets = new Insets(10, 10, 0, 0);
panel.add(passwordLabel, gbc);
passwordField = new JPasswordField(20);
gbc.gridx = 1;
gbc.gridy = 2;
gbc.insets = new Insets(10, 10, 0, 10);
panel.add(passwordField, gbc);
// 验证码
captchaLabel = new JLabel("验证码:");
gbc.gridx = 0;
gbc.gridy = 3;
gbc.insets = new Insets(10, 10, 0, 0);
panel.add(captchaLabel, gbc);
captchaTextField = new JTextField(10);
gbc.gridx = 1;
gbc.gridy = 3;
gbc.insets = new Insets(10, 10, 0, 10);
panel.add(captchaTextField, gbc);
// 登录按钮
loginButton = new JButton("登录");
gbc.gridx = 1;
gbc.gridy = 4;
gbc.insets = new Insets(10, 10, 10, 10);
panel.add(loginButton, gbc);
// 添加面板
add(panel);
// 显示窗口
setVisible(true);
}
public static void main(String[] args) {
new LoginGUI();
}
}
```
以上代码中使用了GridBagConstraints来设置每个组件在布局中的位置和大小,实现了登录界面的各个部分。你可以根据需要进行修改和调整以满足具体需求。
