java - カスタム Java コンポーネントが正しく描画されない

Question

適切に描画されていないカスタム ボタンがあります。左上隅にドットとして表示されます。私は3つのクラスを持っています。1 つはボタン用、1 つはメニューまたは複数のボタンの描画用、およびメニューを呼び出すメイン クラスです。

クラス 1 - ボタン

@Override
protected void paintComponent(Graphics g) {
    g.setColor(Color.white);
    Graphics2D g2d = (Graphics2D) g;
    g2d.drawImage(img, this.x, this.y,this.getWidth(), this.getHeight(), null);
    g2d.setFont(this.font);
    g2d.drawString(this.label, x, y);
}

クラス 2 - メニュー

public void draw(Graphics g, int width, int height) {
    int x, y;       
    for(int i = 0; i < buttons.length; i++) {
        x = (int) (width / 2 - buttons[i].getWidth() / 2);
        y = (int) (height / 2 - buttons[i].getHeight() / 2);

        buttons[i].setBounds(x, y + (i*60), buttons[i].getWidth(), buttons[i].getHeight());
        buttons[i].paintComponent(g);
    }       
}

クラス 3 - メイン

if(gMenu != null) {
                gMenu.draw(g, gWindow.getWidth(), gWindow.getHeight());
            }

編集:私がやろうとしていることを明確にするために、いくつかのカスタム ボタン (コンポーネント) を含むポップアップ メニューを作成します。

編集：描画してもらいましたが、マウスリスナーが機能しません。

ここにメニュークラスがあります

public class Menu extends JComponent {

GameWindow window;

public Menu(GameWindow window) {
    this.window = window;
    this.setVisible(true);
}

public void addChildToPanel(JComponent child) {
    int width = (int) getWidth();
    if(child.getWidth() > width) {
        width = child.getWidth();
    }
    int height = (int) getHeight();
    height += child.getHeight();
    setSize(width, height);

    Dimension screen = new Dimension(window.getWidth(), window.getHeight());
    int x = (screen.width - width) / 2;
    int y = (screen.height - height) / 2;
    setBounds(x, y, width, height);
}
}

ボタン クラス public class MenuButton extends JComponent implement MouseListener {

private BufferedImage img;
private BufferedImage img_h;
private int x, y;
private String label;
private Font font;

private int state = 0;

// state 0 = normal
// state 1 = highlight
// state 2 = pressed

public MenuButton(BufferedImage img, BufferedImage img_h, String label, Font font) {
    this.setPreferredSize(new Dimension(img.getWidth(), img.getHeight()));
    this.img_h = img_h;
    this.img = img;
    this.label = label;
    this.font = font;
    setVisible(true);

    setBounds(0, 0, img.getWidth(), img.getHeight());
    this.addMouseListener(this);
}

@Override
protected void paintComponent(Graphics g) {
    g.setColor(Color.white);
    Graphics2D g2d = (Graphics2D) g;
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

    switch (state) {
    case 0:
        g2d.drawImage(img, this.getBounds().x, this.getBounds().y,this.getWidth(), this.getHeight(), null);
        break;
    case 1:
        g2d.drawImage(img_h, this.getBounds().x, this.getBounds().y,this.getWidth(), this.getHeight(), null);
        break;
    case 2:
        g2d.drawImage(img, this.x, this.y,this.getWidth(), this.getHeight(), null);
        break;
    }

    g2d.setFont(this.font);

    int size = g2d.getFontMetrics(font).stringWidth(this.label);
    int x = this.getBounds().x + this.getWidth() - 20 - size;
    int y = this.getBounds().y + 29;

    g2d.drawString(this.label,x, y);
}

public void setState(int state) {
    this.state = state;
}

@Override
public void mouseClicked(MouseEvent e) {
}

@Override
public void mouseEntered(MouseEvent e) {
    setState(1);
}

@Override
public void mouseExited(MouseEvent e) {
    setState(0);
}

@Override
public void mousePressed(MouseEvent e) {
    setState(2);
}

@Override
public void mouseReleased(MouseEvent e) {
    setState(1);
}

}

public class PauseMenu extends Menu {
