Java 程序在 Swing 中创建圆角边框
java 8object oriented programmingprogramming更新于 2025/9/4 8:44:17
首先创建一个框架:
JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setUndecorated(true);
现在，创建圆角边框:
double x = 50; double y = 50; frame.setShape(new RoundRectangle2D.Double(x, y, 100, 100, 50, 50));
以下是在 Swing 中创建圆角边框的示例:
示例
import java.awt.geom.RoundRectangle2D;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class SwingDemo extends JPanel {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setUndecorated(true);
double x = 50;
double y = 50;
frame.setShape(new RoundRectangle2D.Double(x, y, 100, 100, 50, 50));
frame.setSize(600, 500);
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
}
输出
