如何关闭新开放jframe

我只需点击一下按钮即可处理两个JFrame。当按钮" ADD RECORDS"时,我有2个JFrame(SUC_Forms和add_suc)。在SUC_Forms中单击另一个新的JFrame将显示哪个是add_suc jframe,其中包含用于注册/归档的文本框。当我按下确认并在数据库中插入所有数据时,将弹出一个JDialogbox进行确认。一旦我点击了#34; Ok"两个JFrame将进行处置,然后SUC_Forms-JFrame将再次显示包含更新的数据。我在当前的JFrame如何访问前一个和活动的JFrame时遇到了麻烦。你能帮我解决这个问题吗?提前谢谢..

继承我的打印屏幕。

SUC_Forms代码:

    add_suc add = new add_suc();
    add.show();

add_suc代码:

private void btn_okActionPerformed(java.awt.event.ActionEvent evt){

    int verify = JOptionPane.showConfirmDialog(rootPane,"Are you sure you want to add this record?","", JOptionPane.YES_NO_OPTION);

    if(verify == 0)
    {

由于您要添加新记录的JFrame仍处于打开状态,因此可以使用SUC_Forms中的方法将新记录作为参数传递。为了能够做到这一点,你必须在add_suc中获得对SUC_Forms的引用。例如,您可以在打开此Frame时将此引用传递给add_suc的构造函数。然后,您可以使用对SUC_Forms的引用来调用方法来添加记录。

你的构造函数看起来像这样:

add_suc(SUC_Forms parent)
{}

在SUC_Forms中,您可以创建一个方法:

public void addRecord(-here you pass the required parameters-)
{}

您在add_suc中的方法调用将是:

parent.addRecord(-parameters-);

我希望这对你有所帮助。
