Question

我已经尝试了很多方法来绘制图像作为背景但没有工作，所以我采用了制作一个覆盖屏幕并设置图像的JButton。（我知道，我知道）我如何以正确的方式画出一个？

public class Menu extends JFrame {

private static final long serialVersionUID = 6001404440595750724L;
public static int width = 696;
public static int height = 550;

private JPanel window = new JPanel();
private JFrame frame = new JFrame();

private String Title = "Pixeled Universe";

private JButton play, options, quit, image, multi;
private Rectangle Rplay, Roption, Rquit, Rimage, Rmulti;

private int Bwidth = 200;
private int Bheight = 40;

public static String ico;

public static Socket socket;
public static DataOutputStream out;
public static DataInputStream in;

Sound sound = new Sound();

public boolean connect = true;

public static boolean multiP = false;

public Menu(Component component) {

    frame.setTitle(Title);
    frame.setSize(new Dimension(width, height));
    frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
    frame.add(component);
    frame.getContentPane().add(window);
    frame.setResizable(false);
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
    ico = "Resources/image.ico";
    frame.setIconImage(new ImageIcon(ico).getImage());
    window.setLayout(null);

    drawButtons();
    button1();
    sound.play("Resources/FlashingWinds.wav");
    play();

    frame.repaint();
}

private void button1() {
    image = new JButton("");
    Rimage = new Rectangle(0, 0, width, height);
    image.setBounds(Rimage);
    image.setBorder(null);
    window.add(image);
    if (Tile.test == true) {
        image.setIcon(new ImageIcon("Resources/menubackground.png"));
    } else {
        image.setIcon(new ImageIcon(
                System.getProperty("user.home")
                        + "/AppData/Roaming/PixeledUniverse/Resources/menubackground.png"));
    }
}

private void drawButtons() {

    Roption = new Rectangle(10, 371, Bwidth, Bheight);
    options.setBounds(Roption);
    options.setBorder(null);
    window.add(options);

    quit = new JButton("");
    Rquit = new Rectangle(480, 250, Bwidth, Bheight);
    quit.setBounds(Rquit);
    quit.setBorder(null);
    window.add(quit);

    multi = new JButton("");
    Rmulti = new Rectangle(480, 371, Bwidth, Bheight);
    multi.setBounds(Rmulti);
    multi.setBorder(null);

Answer 1

不要使用null布局，这只是问问题。
您可以使用JLabel代替JButton，相应地设置标签布局管理器并将其他组件添加到其中
仅在完成构建初始UI后调用框架上的setVisible

我怎么画这个？
