如何更改JButton的文本颜色 [英] How to change text color of a JButton

问题描述

我在写一个简单的扫雷游戏，现在工作，但我正在处理漂亮的细节，使每个数字的颜色不同。

I am writing a simple minesweeper game and it works now, but I am working on the pretty details like making each number a different color.

当我尝试在 JButton 上设置文本颜色时出现错误。

I keep running into errors when I try to set the text color on the JButton. I can change the text easily enough and the background, but not the text color specifically.

不断得到的部分是：

total = Integer.toString(count);
jb.setText(total);              
if(count == 1)
    jb.setTextColor(Color.blue);
if(count == 2)
    jb.setTextColor(Color.green);
if(count == 3)
    jb.setTextColor(Color.red);

出于某种原因，我的错误是：

For some reason my error is:

MS.java:109: error: cannot find symbol
                    jb.setTextColor(Color.blue);
                      ^
  symbol:   method setTextColor(Color)
  location: variable jb of type JButton
MS.java:112: error: cannot find symbol
                    jb.setTextColor(Color.green);
                      ^
  symbol:   method setTextColor(Color)
  location: variable jb of type JButton
MS.java:114: error: cannot find symbol
                    jb.setTextColor(Color.red);
                      ^
  symbol:   method setTextColor(Color)
  location: variable jb of type JButton
3 errors
Process javac exited with code 1

这种情况发生在我每次尝试编译时，但是当我改变它说 setBackgroundColor setTextColor 它可以正常工作。

This occurs whenever I try to compile, but when I change it to say setBackgroundColor instead of setTextColor it works just fine.

推荐答案

setTextColor 未定义用于JButton。要设置 JButton 文本颜色，可以使用 setForeground 。

setTextColor is undefined for JButton. To set the JButton text color, you can use setForeground.

button.setForeground(Color.RED);
