如何將圖像添加到JPanel中的JPanel？

我總共有7個JPanel集裝箱。我想添加一個我生成的PNG圖像，或者藉助JPanel中的按鈕（充電器圖像）將其緩衝（012）使用ImageIcon如何將圖像添加到JPanel中的JPanel？

生成的圖像是在326X254
如何將圖像正確地添加到面板？

在這裏，你會發現代碼生成下面的窗口：

如何將圖像proprely添加到JPanel？

創建一個ImageIcon。
將圖標添加到JLabel。
將標籤添加到JPanel。

請參閱How to Use Icons的Swing教程部分以獲取更多信息和工作示例。

此外，從您的發佈代碼中，擺脫所有setPreferredSize()陳述。佈局管理器將確定組件的首選大小。 Swing旨在與佈局經理一起使用。讓佈局經理完成工作。

console = new JTextArea();

當創建一個JTextArea這樣做：

console = new JTextArea(5, 30);

該會建議的大小應該是5行30列。現在，佈局管理器可以根據這些信息計算出一個首選大小。

private BorderLayout BorderGlobalePan, BorderSecondPane, BorderManipPane, ...

變量名不能以大寫字母開頭。你的大部分變量都是正確的，但不是全部。始終如一！！！

frame.setSize(1024, 600);

不要硬編碼大小。你不知道我的電腦的分辨率是多少。請使用pack()方法，讓佈局經理完成他們的工作。
