如何将图像添加到JPanel中的JPanel？

我总共有7个JPanel集装箱。我想添加一个我生成的PNG图像，或者借助JPanel中的按钮（充电器图像）将其缓冲（012）使用ImageIcon如何将图像添加到JPanel中的JPanel？

生成的图像是在326X254
如何将图像正确地添加到面板？

在这里，你会发现代码生成下面的窗口：

如何将图像proprely添加到JPanel？

创建一个ImageIcon。
将图标添加到JLabel。
将标签添加到JPanel。

请参阅How to Use Icons的Swing教程部分以获取更多信息和工作示例。

此外，从您的发布代码中，摆脱所有setPreferredSize()陈述。布局管理器将确定组件的首选大小。 Swing旨在与布局经理一起使用。让布局经理完成工作。

console = new JTextArea();

当创建一个JTextArea这样做：

console = new JTextArea(5, 30);

该会建议的大小应该是5行30列。现在，布局管理器可以根据这些信息计算出一个首选大小。

private BorderLayout BorderGlobalePan, BorderSecondPane, BorderManipPane, ...

变量名不能以大写字母开头。你的大部分变量都是正确的，但不是全部。始终如一！！！

frame.setSize(1024, 600);

不要硬编码大小。你不知道我的电脑的分辨率是多少。请使用pack()方法，让布局经理完成他们的工作。
