如何阻止BorderLayout的中心向东和向西移动? [英] How do I stop center of BorderLayout from taking up east and west?

问题描述

我有一个程序，其中使用BorderLayout，尽管CENTER是一个位置，但EAST和WEST位置并未填充.结果，中心部分扩展到了东西两个部分所在的空间.

I have a program in which I use BorderLayout and the EAST and WEST positions are not filled, though the CENTER one is. As a result, the center component extends to the space where the east and west components would be.

如何防止这种情况?我知道我可以在东方和西方位置使用空白的JPanel，但这似乎很麻烦.

How can I prevent this? I know I could just use a blank JPanel in the east and west positions, but that seems hacky.

推荐答案

如果您想要的是中央面板周围的空白区域，则可以为其添加边框:

If what you want is empty space around your center panel, you can add a border to it:

panel.setBorder(BorderFactory.createEmptyBorder(0, 10, 0, 10);
