选中复选框后，JCheckBox 周围的 EmptyBorder 变得可见

问题描述

我在我的 JCheckBox 周围设置了一个 EmptyBorder(为了缩进它，但这并不重要).当我选择(或取消选择)我的 JCheckBox 时，边框会以黑色虚线的形式围绕它绘制.我什至不想看到这个边界.如何让它不可见?

I've set an EmptyBorder around my JCheckBox (for the purpose of indenting it, but that doesn't really matter). When I select (or deselect) my JCheckBox, the border gets drawn around it as a dashed black line. I don't want to even see this border at all. How do I keep it invisible?

这是我的(简化)代码:

Here is my (simplified) code:

JPanel myPanel = new JPanel();
JCheckBox myCB = new JCheckBox("hello");
myPanel.add(myCB);
myCB.setBorder( new EmptyBorder( 2, 15, 2, 2 ) );

推荐答案

那不是边界.这听起来像是指示组件具有焦点的焦点指示器.所有组件都有某种焦点指示器来向用户提供反馈.

That is not a Border. That sounds like the focus indicator which indicates the component has focus. All components have some kind of focus indicator to give feedback to the user.

公司花费数百万美元来获得一致的 LAF，但如果您真的认为自己的 LAF 更好，那么您可以使用:

Companies spend millions of dollars to have a consistent LAF, but if you really think your LAF is better then you can use:

checkbox.setFocusPainted( false );
