我正在尝试制作一个二十一点游戏,希望采用图形面板(包括图片、卡牌绘画等)设计程序,并在该面板上方加一个JPanel 按钮面板。我希望这个JPanel是透明的,以便下面的图形面板可见,但按钮不会变为透明。
如果有人能指导我正确的方向吗?
图形层:

图形层:
public class GraphicsBoard {
String[] fileName = { "cards.png", "BlackJackBoard.png" };
ClassLoader cl = GraphicsBoard.class.getClassLoader();
URL imgURL[] = new URL[2];
Toolkit tk = Toolkit.getDefaultToolkit();
Image imgCards, imgBG;
public GraphicsBoard() throws Exception {
for (int x = 0; x < imgURL.length; x++)
imgURL[x] = cl.getResource("pictures/" + fileName[x]);
imgCards = tk.createImage(imgURL[0]);
imgBG = tk.createImage(imgURL[1]);
}
public void paintComponent(Graphics g) {
g.drawImage(imgBG, 0, 0, 550, 450, 0, 0, 551, 412, this);
Graphics2D g2 = (Graphics2D) g;
for (int x = 0; x <= 550; x += 50) {
g2.drawLine(x, 0, x, 450);
g2.drawString("" + x, x + 5, 20);
}
for (int y = 5; y <= 450; y += 50) {
g2.drawLine(0, y, 550, y);
g2.drawString(" " + y, 0, y + 20);
}
}
}
按钮层:
public class OverBoard extends JPanel implements ActionListener{
JButton btnDeal = new JButton("Deal");
public OverBoard(){
btnDeal.addActionListener(this);
add(btnDeal);
setOpaque(false);
}
}
我希望按钮层处于图形层的顶部。
