要在 Java 中创建无边框窗口，请不要装饰窗口。以下是创建无边框窗口的示例 −
示例
package my;
import java.awt.GraphicsEnvironment;
import java.awt.GridLayout;
import java.awt.Point;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.JWindow;
import javax.swing.SwingConstants;
public class SwingDemo {
public static void main(String[] args) throws Exception {
JWindow frame = new JWindow();
JLabel label1, label2, label3;
frame.setLayout(new GridLayout(2, 2));
label1 = new JLabel("Id", SwingConstants.CENTER);
label2 = new JLabel("Age", SwingConstants.CENTER);
label3 = new JLabel("Password", SwingConstants.CENTER);
JTextField emailId = new JTextField(20);
JTextField rank = new JTextField(20);
JPasswordField passwd = new JPasswordField();
passwd.setEchoChar('*');
frame.add(label1);
frame.add(label2);
frame.add(label3);
frame.add(emailId);
frame.add(rank);
frame.add(passwd);
Point center = GraphicsEnvironment.getLocalGraphicsEnvironment().getCenterPoint();
int width = 500;
int height = 200;
frame.setBounds(center.x - width / 2, center.y - height / 2, width, height);
frame.setVisible(true);
}
}
