小编Jos*_* Mo的帖子

我坐在电脑前大约13个小时,我觉得我的眼睛正在流血.我发现了一个我称之为GuiGenie的小编辑.它非常适合用按钮和所有好东西创建窗口.问题是我想在我的第一个菜单中单击一个按钮,然后打开我制作的其他菜单.我刚开始编程4周前,所以我是一个完整的菜鸟.我有一种感觉,因为主要的方法弄乱了,但我不知道和13个小时坐在这里尝试数百万的东西让我发疯:)这是我到目前为止

public class MyPanel extends JPanel {
private JTextField How;
private JLabel jcomp2;
private JLabel jcomp3;
private JButton jcomp4;

public MyPanel() {
    //construct components
    How = new JTextField (1);
    jcomp2 = new JLabel ("How long were you parked?");
    jcomp3 = new JLabel ("Minutes");
    jcomp4 = new JButton ("openNewWindow");

    //adjust size and set layout
    setPreferredSize (new Dimension (315, 85));
    setLayout (null);

    //add components
    add (How);
    add (jcomp2);
    add (jcomp3);
    add (jcomp4);

    //set component …

我希望它在按下按钮时关闭活动窗口并打开新窗口.

我得到它打开一个新窗口,但旧的仍然在那里.我试图实现frame.dispose(); 但我不认为我做得对.

这就是我所拥有的
