有没有办法让BorderLayout的东边、南边和西边更大？
有没有办法让BorderLayout的东边、南边和西边更大？
提问于 2014-06-10 07:34:32
我一直在为元素周期表的GUI编写代码。我有一切看起来都很好，但是我已经添加到东，西和南边界的许多按钮(金属，非金属和稀土)有一个"...“作为按钮的文本，而不是像中心这样的元素符号(过渡金属)。这是因为当我执行frame.pack()时，东部、南部和西部的按钮被塞进了它们各自的边界。有没有办法让这些边框稍微大一点，这样按钮就不会那么塞满了，从而显示出它们想要的标题，而不是"..."？我尝试过更改框架大小和每个按钮的首选按钮大小(第14和137行)，但pack()方法似乎覆盖了这一点。

NORTH、SOUTH、EAST和WEST位置由组件的首选大小决定
最好的选择是首先避免与setPreferredSize打交道，让组件和布局管理器在那里工作。
如果您需要提供额外的填充，可以使用EmptyBorder或边框或布局管理器的组合，它们为您提供了指定填充的能力，如GridBagLayout (用于最好的控制量)
此外，请避免在窗口上使用setSize，而应使用pack，并允许布局管理器根据组件、字体和其他渲染管道的详细信息来计算窗口的首选大小
例如..。
