我正在尝试为 JButton/JTabbedPane 的特定实例覆盖“nimbusBase”颜色，但没有成功。 只有组件的特定属性，例如“Button.background”，正在工作。 有什么想法吗？
UIDefaults dialogTheme = new UIDefaults();
// dialogTheme.put(“nimbusBase”, Color.orange);
// dialogTheme.put("nimbusBlueGrey", Color.blue);
dialogTheme.put("Button.background", Color.yellow);
JButton dialogButton = new JButton("North");
dialogButton.putClientProperty("Nimbus.Overrides.InheritDefaults", true);
dialogButton.putClientProperty("Nimbus.Overrides", dialogTheme);
最佳答案
您可以将所有“nimbusBase”组件的颜色添加到 LookAndFeelDefaults
UIDefaults defaults = UIManager.getLookAndFeelDefaults();
defaults.put("nimbusBase", new ColorUIResource(210, 0, 210));
或者您编写的特定组件。可能会更新 componentTreeUI。
...
dialogTheme.put("Button.background", new ColorUIResource(0, 0, 210));
...
dialogButton.putClientProperty("Nimbus.Overrides", dialogTheme);
SwingUtilities.updateComponentTreeUI(dialogButton);
我从不为特定组件覆盖 "nimbusBase"。
我找到了一个不错的Nimbus Theme Creator，可以展示将一个Nimbus Default Color改成所有Components的效果:http://aephyr.googlecode.com/svn/trunk
编辑
您可以“复制”Painter，修改它们并通过 UIDefaults 设置它们:
带有 nimbusOrange JTabbedPane 和普通 GUI 的示例。
public class Example {
static public void main( String[] s ) throws Exception {
for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
UIManager.setLookAndFeel(info.getClassName());
break;
}
}
EventQueue.invokeLater( new Runnable() {
@Override
public void run() {
JFrame frame = new JFrame();
frame.getContentPane().setLayout( new BorderLayout() );
frame.setBounds( 50, 50, 600, 600 );
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
JTabbedPane pane = new JTabbedPane();
pane.addTab( "Lorem", new JLabel("Lorem") );
pane.addTab( "Ipsum", new JLabel("Ipsum") );
pane.addTab( "Dolor", new JLabel("Dolor") );
pane.addTab( "Sit", new JLabel("Sit") );
pane.addTab( "Amet", new JLabel("Amet") );
UIDefaults dialogTheme = new UIDefaults();
dialogTheme.put("TabbedPane:TabbedPaneTab[Enabled].backgroundPainter", new Painter(Painter.BACKGROUND_ENABLED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Disabled].backgroundPainter", new Painter(Painter.BACKGROUND_DISABLED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Enabled+MouseOver].backgroundPainter", new Painter(Painter.BACKGROUND_ENABLED_MOUSEOVER));
dialogTheme.put("TabbedPane:TabbedPaneTab[Enabled+Pressed].backgroundPainter", new Painter(Painter.BACKGROUND_ENABLED_PRESSED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Disabled+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_DISABLED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Focused+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_FOCUSED));
dialogTheme.put("TabbedPane:TabbedPaneTab[MouseOver+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_MOUSEOVER));
dialogTheme.put("TabbedPane:TabbedPaneTab[Focused+MouseOver+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_MOUSEOVER_FOCUSED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Pressed+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_PRESSED));
dialogTheme.put("TabbedPane:TabbedPaneTab[Focused+Pressed+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_PRESSED_FOCUSED));
dialogTheme.put("TabbedPane:TabbedPaneTabArea[Disabled].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_DISABLED));
dialogTheme.put("TabbedPane:TabbedPaneTabArea[Enabled+MouseOver].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_ENABLED_MOUSEOVER));
dialogTheme.put("TabbedPane:TabbedPaneTabArea[Enabled+Pressed].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_ENABLED_PRESSED));
dialogTheme.put("TabbedPane:TabbedPaneTabArea[Enabled].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_ENABLED));
pane.putClientProperty("Nimbus.Overrides.InheritDefaults", Boolean.TRUE);
pane.putClientProperty("Nimbus.Overrides", dialogTheme);
JTabbedPane secondPane = new JTabbedPane();
secondPane.addTab( "Lorem", new JLabel("Lorem") );
secondPane.addTab( "Ipsum", new JLabel("Ipsum") );
secondPane.addTab( "Dolor", new JLabel("Dolor") );
secondPane.addTab( "Sit", new JLabel("Sit") );
secondPane.addTab( "Amet", new JLabel("Amet") );
frame.getContentPane().setLayout( new BorderLayout() );
frame.getContentPane().add( pane, BorderLayout.NORTH );
frame.getContentPane().add( secondPane, BorderLayout.CENTER );
frame.setVisible( true );
}
});
}
}
带有 nimbusOrange 的 Painter 类
注意: 我在这个 Painter 示例中删除了绘画方法。因为这段代码太长了。只需通过 com.sun.java.swing.plaf.nimbus.TabbedPaneTabbedPaneTabPainter 的复制和粘贴添加它们。

我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为

我在我的项目中添加了一个系统来重置用户密码并通过电子邮件将密码发送给他，以防他忘记密码。昨天它运行良好(当我实现它时)。当我今天尝试启动服务器时，出现以下错误。=>BootingWEBrick=>Rails3.2.1applicationstartingindevelopmentonhttp://0.0.0.0:3000=>Callwith-dtodetach=>Ctrl-CtoshutdownserverExiting/Users/vinayshenoy/.rvm/gems/ruby-1.9.3-p0/gems/actionmailer-3.2.1/lib/action_mailer
我有一个包含模块的模型。我想在模块中覆盖模型的访问器方法。例如:classBlah这显然行不通。有什么想法可以实现吗？ 最佳答案 您的代码看起来是正确的。我们正在毫无困难地使用这个确切的模式。如果我没记错的话，Rails使用#method_missing作为属性setter，因此您的模块将优先，阻止ActiveRecord的setter。如果您正在使用ActiveSupport::Concern(参见thisblogpost)，那么您的实例方法需要进入一个特殊的模块:classBlah
我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server

我正在查看instance_variable_set的文档并看到给出的示例代码是这样做的:obj.instance_variable_set(:@instnc_var,"valuefortheinstancevariable")然后允许您在类的任何实例方法中以@instnc_var的形式访问该变量。我想知道为什么在@instnc_var之前需要一个冒号:。冒号有什么作用？ 最佳答案 我的第一直觉是告诉你不要使用instance_variable_set除非你真的知道你用它做什么。它本质上是一种元编程工具或绕过实例变量可见性的黑客攻击
