菜鸟提问：如何设置Swing控件不可用(即setEnabled(false))时的字体颜色？需要一个通用方法，高手帮我呀！

[xiaoyongjun]

因为Swing输入控件（主要是JCombobox、JTextField、JSpinner、JTextArea等）在不可用时，默认字体颜色都是灰色，即Gray，这种颜色看不清楚，所以我想改变输入控件不可用时的字体颜色，但又不能每个控件都去手动设置，因为控件非常多，所以想用一个通用的方法，写一个通用类，在这个类中定义方法来设置控件不可用时的字体颜色，Swing控件继承这个类，这只是初步想法，各位高手有没有相关的代码，贴出来看看？

非常着急，只要大家参与，都有分相赠！

[dqpichd]

关注ing，学习ing，高手们，发发言呀！我也很想知道！

原来印象错了 ...
不好意思。
看来只能用uimanager设置了。

//打印所有的颜色属性
UIDefaults uiDefaults = UIManager.getLookAndFeelDefaults();
Enumeration keys = uiDefaults.keys();
while (keys.hasMoreElements()) {
Object key = keys.nextElement();
Object val = uiDefaults.get(key);

if (val instanceof Color) {
System.out.println(key.toString());
}
}

//设置TextField,Label,Button不可用状态的表现颜色
uiDefaults.put("TextField.inactiveForeground", Color.BLUE);
uiDefaults.put("Label.disabledForeground", Color.BLUE);
uiDefaults.put("Button.disabledText", Color.BLUE);

其他的属性字段名称自己去找.

不用继承什么类，在程序一开始设置Swing的UI管理器UIManager就可以了，下面是将JTextField的非可用状态文本颜色设置为红色
//Key:[TextField.inactiveForeground]
UIManager.put("TextField.inactiveForeground", new Color(255, 0, 0)); // 设置为红色，一句代码就搞定了
JTextField text = new JTextField(15);
text.setText("ABCDEF");
text.setEnabled(false);

[xiaoyongjun]

采用了两位仁兄的方法，还是没有达到我的要求，感觉非常沮丧！我的代码如下，二位能否再帮我一下，感激不尽！
public Frame1() {
try {
jbInit();
}
catch (Exception exception) {
exception.printStackTrace();
}
}

private void jbInit() throws Exception {
init();
setMyUI();
contentPane = (JPanel)this.getContentPane();
contentPane.setLayout(xyLayout1);
this.setSize(400, 600);
btnTest1.setText("Test1");
txtfldTest1.setText("jTextField1");
btnEnabledFalse.setMargin(new Insets(0, 0, 0, 0));
btnEnabledFalse.setText("setEnabledFalse");
btnEnabledFalse.addActionListener(new Frame1_btnEnabledFalse_actionAdapter(this));
btnEnabledTrue.setMargin(new Insets(0, 0, 0, 0));
btnEnabledTrue.setText("setEnabledTrue");
btnEnabledTrue.addActionListener(new Frame1_btnEnabledTrue_actionAdapter(this));
this.addWindowListener(new Frame1_this_windowAdapter(this));
contentPane.add(btnTest1, new XYConstraints(98, 81, 88, 24));
contentPane.add(txtfldTest1, new XYConstraints(99, 118, 94, 22));
contentPane.add(combTest1, new XYConstraints(97, 156, 95, -1));
contentPane.add(btnEnabledFalse, new XYConstraints(228, 151, 123, 26));
contentPane.add(btnEnabledTrue, new XYConstraints(227, 116, 122, 26));
contentPane.add(spinTest1, new XYConstraints(96, 193, 97, 20));
}

private void setMyUI() {
UIDefaults u = UIManager.getDefaults();
Enumeration elements = u.keys();
for (; elements.hasMoreElements(); ) {
Object o = elements.nextElement();
System.out.println(o + ":" + u.get(o));
}

UIManager.put("TextField.inactiveForeground", Color.blue);
UIManager.put("Button.disabledText", Color.black);
UIManager.put("ComboBox.disabledForeground", Color.black);
UIManager.put("Spinner.foreground", Color.black);
}

private void init() {
combTest1.removeAllItems();
combTest1.addItem("xiaoyongjun");
combTest1.addItem("chengdan");
combTest1.setSelectedIndex(0);

btnTest1.setEnabled(false);
combTest1.setEnabled(false);
txtfldTest1.setEnabled(false);
spinTest1.setEnabled(false);
}
这种方法对JCombobox和JButton可行，但是对于JTextField没有效果！

[yonghar]

我这里测试没有问题。
你确定txtfldTest1是JTextField吗？
欧在怀疑是不是拉错,用了JLabel。

[mq612]

只要你的组件和Key对应就不会有问题

[xiaoyongjun]

我这里怎么测试都不行呀，怎么回事？太奇怪了，二位高手能否告知联系方式，我的QQ：25403519

二位高手用用我的代码测试了吗？我是在JBuilder2006里面测试的！

[xiaoyongjun]

最后麻烦两位高手一下，希望能和你们取上联系，就着一个问题，以后决不打扰！

[mq612]

先后顺序换一下试试
setMyUI();
init();

[xiaoyongjun]

yonghar(xio)：能把你测试的全部代码发给我吗？我看看，看问题出在哪了？我的邮箱[e-mail]，非常感谢！

各位高手，我实在是找不出原因了！高手帮我看看吧，能解决我的问题，必将重谢！

[default_class]

好像不行,要不然你换background的颜色吧,不就明显了.

[default_class]

enabled为true时,控件处于不活动状态,默认字体为灰色.要不然只有贴皮肤了.

[xiaoyongjun]

default_class():好像不行,要不然你换background的颜色吧,不就明显了.

这种方法不好，setEnabled(false)时，foreground颜色为gray，这时你把background换成什么颜色，才清晰呢？默认为白色，估计没有更清晰的方法了吧。

老兄，怎么个贴皮肤方法？没用过！有没有代码试一下！

[dqpichd]

我也遇到同样的问题，希望能给与解决！关注ing!

[dqpichd]

高手都不在呀！

[mgj216]

若楼主想要去做一个通用的class,这样真的不错.
如这样来写可以试试,直接传入组件的名称就可以.

class Component
{
public Component(Component c1)

if (c1 instanceof JTextComponent){
}
else if(c1 instanceof ......){
}

}

[default_class]

jTextArea1.setDisabledTextColor(Color.red);
可以设置Disabled时字的颜色
