英文:
centering a button in 2 grids using GridBagLayout (Java Swing)
问题
我想知道是否有可能在GridBagLayout的两个X网格中居中一个JButton？我已经在API中进行了一些搜索，但没有找到太多信息。我还画了一张小图片，以阐明我的尝试。
谢谢！

Thank you!

阅读Swing教程中关于如何使用GridBagLayout的部分。
您需要关注“指定约束”部分：
gridwidth约束允许按钮跨越多列anchor约束允许按钮在两列之间居中。- 需要关闭
fill约束。
上述假设您实际上在每列中的面板上有其他组件。您不能随意地让单个组件占用两列。
因此，请从教程中的演示代码开始，并将其修改为底部居中显示按钮。

Read the section from the Swing tutorial on How to Use GridBagLayout.
You would need to concentrate on the Specifying Constraints section:
- the
gridwidthconstraint will allow the button to span multiple columns - the
anchorconstraint will allow the button to be centered within the two columns. - the
fillconstraint will need to be turned off.
The above assumes that you actually have other components on the panel in each of the columns. You can't just randomly say a single component takes up two columns.
So start with the demo code in the tutorial an modify it to have the button on the bottom centered.
