使TextArea的背景不透明

Question

我想让TextArea的背景变得不透明。我在netbeans上使用swing gui表单。

我想重叠图像前面的指令（see this picture），但问题是如果图像位于图像的前面，则无法看到文本。我真的不知道不透明的背景是不是这里的问题（我使用分层窗格有一个JLabel图片所在的位置，并重叠TextArea，我放置了我的指示）。

你能帮我弄清问题是什么吗？

这是代码：

import java.awt.Color;
import javax.swing.ImageIcon;
import javax.swing.JFrame;

public class About extends javax.swing.JDialog {

public About(JFrame owner) {
    super(owner, true);
    initComponents();
    setSize(500, 500);
    setLocation(300, 120);
    getContentPane().setBackground(Color.getHSBColor(204, 204, 255));
    jLabel1.setIcon(new ImageIcon("HangmanStartlight.jpg"));

 }

    jTextArea1 = new javax.swing.JTextArea();

    setDefaultCloseOperation(javax.swing.WindowConstants.DISPOSE_ON_CLOSE);

    jLabel1.setText("jLabel1");
    jLabel1.setBounds(0, 0, 420, 290);
    jLayeredPane1.add(jLabel1, javax.swing.JLayeredPane.DEFAULT_LAYER);

    jTextArea1.setColumns(20);
    jTextArea1.setFont(new java.awt.Font("Microsoft Sans Serif", 1, 14)); // NOI18N
    jTextArea1.setForeground(new java.awt.Color(51, 0, 51));
    jTextArea1.setRows(5);
    jTextArea1.setText("Hangman\n\nGuess the \"HIDDEN PHRASE\" to proceed to the next\nlevel.

尝试使用Background Panel中的一个提示。

Answer 2

编写您自己的组件，在屏幕上手动绘制文本。这就是用Java制作游戏的方式，而不是Swing ......
