禁用JButton焦点边框 [英] Disable JButton focus border

问题描述

我在Java中遇到JButton的问题。基本上，我想禁用按钮的边框（按钮添加到JDesktopPane）。

I have a problem with JButton in Java. Basically, I want to disable the button's border (the button is added to JDesktopPane ).

这是我的代码：

 JButton j = new JButton("BUTTON");
 j.setIcon(icon1); //icon1 : icon//
 j.setFocusable(true);
 j.setContentAreaFilled(false);
 j.setBounds(90, 20, 130, 30);
 dtp.add(j); //dtp : JDesktopPane//

它可以让边框像这张图片一样消失：

It could let the border disappear like in this image:

但当我点击鼠标（未移动）到按钮时，按钮周围有一个点边框，如下所示：

But when my mouse is clicked (not moved around) into the button, there is a "dot" border around the button, like this:

那么，怎么可能我设置了按钮，这样当我不在按钮区域移动鼠标时，它仍然像第一个图像一样设置，但是当我移动鼠标时，按钮周围有一个方形（浅蓝色背景）？

So, how could I set the button so that when I don't move the mouse around the button area, it's still set like the first image, but when I move the mouse around, there's a square around the button (with a light-blue background)?

推荐答案

这不是边界。这是焦点。你可以使用以下方法删除它：

That is not border. It's focus. You can remove it using:

jButton1.setFocusPainted(false);
