以下是我想要的:
您可以使用EmptyBorder将每个复选框推到中间。请尝试下面的方法,并检查是否有帮助
oilChangeCB=新的JCheckBox(“换油($26.00)”//换油
oilChangeCB.setboorder(BorderFactory.createEmptyBorder(0,175,0,0));
lubeJobCB=新的JCheckBox(“润滑工作($18.00)”)//润滑油工作
lubeJobCB.setboorder(BorderFactory.createEmptyByOrder(0,175,0,0));
散热器冲洗CB=新的JCheckBox(“散热器冲洗($30.00)”)//散热器冲洗
散热器冲洗cb.setBorder(BorderFactory.createEmptyByOrder(0,175,0,0));
transmissionFlushCB=新的JCheckBox(“变速器刷新($80.00”);//变速器刷新

如果你想做什么,用GridLayout是完全不可能的。在GridLayout下,所有单元格的尺寸都是相等的。实际上,在每个网格中添加一个面板数组是一个技巧
将网格中每个面板的对齐方式设置为FlowLayout.LEFT
。这样您可以将所有7个复选框居中。
但是,第8个复选框带有一个文本字段。在这种情况下,我们需要将网格的中心列调整为更大的宽度,以便它可以容纳一行中的两个组件
要做到这一点,您需要一个不同的布局。GridBagLayout将能够做到这一点。按照您的意愿,使用GridLayout是不可能做到的。在GridLayout下,所有单元格的尺寸都是相等的。实际上,在每个网格中添加一组面板是一个技巧 将网格中每个面板的对齐方式设置为
