更改Java Swing组件焦点指示器的颜色 [英] Change the color of the Java Swing Component Focus indicator

问题描述

我有一个JButton，JTextField和一个JTable的JPanel，TAB键遍历这些组件，如预期的那样，围绕组件（或JTable的单元格）绘制的黑盒子有焦点。如何更改黑盒焦点指示器的颜色？

解决方案

选择外观是在每个组件的UI委托的控制下，在 如何设置外观 。

作为一个具体的例子，在某些L& Fs上，当程序启动时，你可以重写默认值：

pre code> UIManager.put（Button.focus，Color.red）;

I have a JPanel with a JButton, JTextField and a JTable, and the TAB key traverses these components as expected with a little black box drawn around the component (or cell in case of the JTable) that has focus. How can I change the color of the black-box focus indicator?

解决方案

The selection appearance is under the control of each component's UI delegate, discussed in How to Set the Look and Feel.

As a concrete example, on certain L&Fs, you can override the default value when your program starts up:

UIManager.put("Button.focus", Color.red);
