如何在Java中製作3D圓角JLabel？

Question

我知道有一種方法可以擴展JLabel繪製3D邊框和繪製圓形邊框的方法，但是如何獲得這兩種邊框？這裏是我的代碼

protected void paintComponent(Graphics g) { 
    g.setColor(getBackground()); 
    g.fillRoundRect(0, 0, getWidth()-1, getHeight()-1, 25, 25); 
    g.fill3DRect(10, 10, 30, 30, true); 
    super.paintComponent(g); 

Answer 1

使用LineBorder圓角或TextBubbleBorder的變體。

Answer 2

你參考這個代碼來創建圓角的JLabel：

import java.awt.*; 
import javax.swing.*; 
import javax.swing.border.*; 

public class RoundedLineBorder extends JPanel { 

    public RoundedLineBorder() { 
     super(true); 
    setLayout(new BorderLayout()); 

     JLabel label = new JLabel("Rounded Corners"); 

     label.setHorizontalAlignment(JLabel.CENTER); 

    LineBorder line = new LineBorder(Color.blue, 2, true); 

     label.setBorder(line); 

     add(label, BorderLayout.CENTER); 
    } 

    public static void main(String s[]) { 
     JFrame frame = new JFrame("Rounded Line Border"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setSize(500, 200); 
     frame.setContentPane(new RoundedLineBorder()); 
     frame.setVisible(true); 
    } 
}
