我是摇摆新手，
我正在创建一个包含TopPanel和底部面板的窗口
在 TopPanel：中，我添加了4个组合，3个文本字段，一个按钮和一个Label（此标签用于选择颜色）。
在 BottomPanel： JTable中，上面的TopPanel元素各有一列。
问题1：当我点击jlabel并选择一种颜色（例如红色）时，我将其设置为topPanel jlabel的背景，它工作正常，并点击顶部面板的添加按钮，它成功添加到jtable和color列也很好（即红色）。
但是，当我从toppanel jlabel中选择一种颜色（例如;绿色）时，它的背景变化很好但是当我点击toppanel的任何组合框时，底部面板jtable的颜色列会改变
当我点击“添加”按钮时也会发生同样的事情
问题2：当我更改toppanel的一个jcombo时，调用所有其他jcombo框的操作performe事件
这是我的代码
public class MultiCompareWindow extends MultiCompareWindowElements implements
ActionListener {
public static JFrame jf = new JFrame();
public static void main(String args[]) {
jf.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
MultiCompareWindow mp = new MultiCompareWindow();
mp.getJTablePanel();
jf.add(mp.getMainPanel());
Vector<String[]> data = new Vector<String[]>();
String[] str = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" };
data.add(str);
mp.setDefinedSizeToElements();
jf.setVisible(true);
