JAVA中“选项卡”功能是怎样实现的?
JAVA中“选项卡”功能是怎样实现的?
就是像在桌面上右键菜单中点“属性”时弹出来的那种界面,
有“主题”、“桌面”、“屏保”之类的那种选项卡,
可以在一个选项卡中点“应用”来保存结果,也可以最后一起点“确定”来保存。
这一系列的功能是怎样实现的?
如果没有详细的实现过程,就帮忙把涉及到的方法给出来就可以。
多谢了!

呵呵,给你写了一个以假乱真的,自己完善一下吧。供参考:
Java code

public class TabbedDialog extends JDialog implements ActionListener {
    
    private Map<String, JPanel> panels;
    private MainPane mainPane;
    private JButton ok = new JButton("OK");

    private JButton apply = new JButton("Apply");
    
    private class MainPane extends JPanel {

        JTabbedPane tabs;

        MainPane() {
            setLayout(new BorderLayout(6, 6));
            tabs = new JTabbedPane();
            add(BorderLayout.CENTER, tabs);
            add(BorderLayout.SOUTH, new Buttons());
        }
