提问by Patrick
I am making a game and when I disable a button with setEnabled(false);the buttons turns grey which clashes with the other colors in the game. Is their a way to change the color of the button when it is disabled?

You can add HTML coding to your button which gives a large range of flexibility, even to disabled buttons.
您可以向按钮添加 HTML 编码，这提供了很大的灵活性，甚至是禁用的按钮。
Example: button.setText("<html><font color = red>3</font></html>");

Calling setContentAreaFilled(false)on a button will make a button look as if it is disabled, even if it is not. It doesn't, however, seem to work the other way around.
在按钮上调用setContentAreaFilled(false)将使按钮看起来好像被禁用，即使它不是。然而，它似乎并没有反过来工作。
If you don't need your button to look enabled, then it is a nice fix.
如果您不需要按钮看起来已启用，那么这是一个不错的解决方案。

If you are talking about the text, then you might be able to use the UIManager to change the disabled foreground color. Check out the UIManager Defaults.
如果您正在谈论文本，那么您也许可以使用 UIManager 来更改禁用的前景色。查看UIManager Defaults。

The button's ButtonUIcontrols the disabled text color. Luckily, you can change it:
该按钮ButtonUI控制禁用的文本颜色。幸运的是，您可以更改它：
button1.setUI(new MetalButtonUI() {
protected Color getDisabledTextColor() {
return Color.BLUE;
}
});
button1.setEnabled(false);
button2.setUI(new MetalButtonUI() {
protected Color getDisabledTextColor() {
return Color.RED;
}
});
button2.setEnabled(false);

i am not 100% on this, but i think you can overwrite the paint method of the button's glasspane to overlay it with the color of your choice.
我不是 100% 对此，但我认为您可以覆盖按钮玻璃窗格的绘制方法，以将其覆盖为您选择的颜色。
here is a tutorial on the panes of a container:
