问题描述
我正在尝试为我正在制作的应用程序编写代码，我的主框架上有 6 个按钮。当我按下其中一个按钮时，它会调出一个设置了选项卡式布局的框架。
我已正确编码选项卡式框架，当我将每个框架设置为可见时，它们会出现在屏幕上，但在按下按钮时不会出现。
我有连接到按钮和框架的动作侦听器以及构造函数，但由于某种原因，我无法让我的代码正常工作。
我已经添加了我的驱动程序和我试图相互连接的前两个表单。

//@param args the command line arguments
public static void main(String[] args) {
// Todo code application logic here

当我运行它时，我得到了这个图像。 simpsonsFrame 这是当我单击 Homer 按钮时发生的情况，然后我必须将其最大化才能看到空白屏幕。homerFrame。 当我将 homerFrame 设置为可见时，它会显示如果按下按钮会出现什么。它显示 homerFrame 然后它显示 simpsonFrame。homersetVisible true
