充实这个想法.

• 不要扩展框架，只需保留对面板的引用即可.
• 使面板为GridLayout或BorderLayout(任何不受限制地添加到其中的单个组件，将被拉伸到可用的宽度和高度).
• 按照上面的代码片段中的操作，对该面板进行足够的填充.
• 将该面板添加到主框架(也是唯一框架)的CardLayout卡中.
• (如有必要)翻转到该卡.

• Don't extend frame, simply keep a reference to a panel.
• Make the panel a GridLayout or BorderLayout (any single component added to either with no constraint, will be stretched to the available width & height).
• Fill that panel much as you are doing in the code snippet above.
• Add that panel to a card of a CardLayout in the main (and only) frame.
• (If necessary) flip to that card.
