我创建了一个简单的框架，称之为F1，其中只包含一个按下按钮打开一个新框架，称之为F2。现在当我关闭F2时，即使F1和F2一起关闭。我如何克服这一点？为什么关闭子框架也是Java swing中的主框架？
当我关闭F2只F2应该被关闭，因为它是一个子帧和当我关闭F1 F1和F2应该被关闭为F1是主框架
这里是主框架的代码（ F1）

public class NewJFrame1 extends javax.swing.JFrame {
public NewJFrame1() {
initComponents();

和副车架的代码是..

虽然我没有写code..it是使用NetBeans做..
谢谢。
请勿使用GUI构建器。 –
