JButton，其边框和按钮本身之间具有填充 [英] JButton with padding between its border and the button itself

问题描述

我有一个JButton，它的背景为绿色，边框为LineBorder.我想在按钮和边框之间插入一个空格，这是一种填充. 我已经尝试过setMargin(new Insets(x，y，t，z))，但似乎无法正常工作. 这是我的代码.

I've a JButton that has its background green-colored and its border as a LineBorder. I would like to insert a space between the button and the border, a kind of padding. I've tried with setMargin(new Insets(x,y,t,z)) but it seems not working. This is my piece of code.

JButton JBtn=new JButton("sdfd");
JBtn.setBorder(BorderFactory.createLineBorder(Color.CYAN,5));
JBtn.setBackground(Color.GREEN);
JBtn.setMargin(new Insets(5,5,10,10));

有什么建议吗?

推荐答案

边框是按钮的一部分，单击边框将单击按钮.您可以将背景设置为绿色，然后在背景上绘制边框:

The borders are part of the button and clicking on them will click the button. You can set the background as green, then paint borders over the background:

jBtn.setBackground(Color.GREEN);
jBtn.setBorder(BorderFactory.createCompoundBorder(
               BorderFactory.createLineBorder(Color.CYAN, 5),
               BorderFactory.createLineBorder(Color.BLACK, 20)));

我已经尝试过使用setMargin(new Insets(x，y，t，z))，但似乎无法正常工作.

I've tried with setMargin(new Insets(x,y,t,z)) but it seems not working.

由于您阅读了setMargin的文档，因此您会看到

Because if you read the documentation for setMargin you'll see that

[...]如果在按钮上设置了非默认边框，则是Border对象负责创建适当的边距空间(否则此属性将被有效地忽略).

[...] if a non-default border is set on the button, it is that Border object's responsibility to create the appropriate margin space (else this property will effectively be ignored).

还要为类保留大写名称，将JBtn重命名为jBtn.

Also, reserve uppercase names for classes, rename JBtn to jBtn.
