JComboBox自定义单元格渲染器-how以获取组合的isEnabled()状态？

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

public class CustomCellRenderer extends DefaultListCellRenderer {

    @Override
    public Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
        Component component = super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);

        if (value instanceof JComboBox) {
            JComboBox<?> comboBox = (JComboBox<?>) value;
            boolean isEnabled = comboBox.isEnabled();
            // 在这里可以根据isEnabled的值来进行相应的处理
            // 例如修改单元格的背景色或者添加额外的图标等

            // 示例：修改单元格的背景色
            if (isEnabled) {
                component.setBackground(Color.WHITE);
            } else {
                component.setBackground(Color.GRAY);
            }
        }

        return component;
    }
}
