java – 设置外观颜色

我正在使用Nimbus Look&感觉我的Java Swing应用程序.
L& F看起来很棒,但我需要更改一些设置(字体,颜色……)以适应我公司的企业形象.

以下代码设置整个应用程序的L& F：

try {
    for( LookAndFeelInfo info : UIManager.getInstalledLookAndFeels() ) {
        if( "Nimbus".equals( info.getName() ) ) {
            UIManager.setLookAndFeel(info.getClassName());
            customizeNimbusLaF();
            break;
        }
    }
}
catch( Exception e ) {
    LogUtility.warning( "cannot set application look and feel" );
    LogUtility.warning( e.getMessage() );
}

代码确实如此(设置Nimbus Look& Feel).
问题是,customizeNimbusLaF()不起作用,正如我所期望的那样.

private final void customizeNimbusLaF() {       
    UIManager.put( "control" , UIConstants.GREY_LIGHT );
    UIManager.put( "nimbusAlertYellow" , UIConstants.YELLOW );
    UIManager.put( "nimbusBase" , UIConstants.GREY_DARK );
    UIManager.put( "nimbusDisabledText" , UIConstants.GREY_DARK );
    UIManager.put( "nimbusFocus" , UIConstants.BLUE_LIGHT );
    UIManager.put( "nimbusGreen" , UIConstants.GREEN );
    UIManager.put( "nimbusInfoBlue" , UIConstants.BLUE_MIDDLE );
    UIManager.put( "nimbusRed", UIConstants.RED );
    UIManager.put( "nimbusSelectionBackground",
    UIConstants.BLUE_MIDDLE );

    UIManager.put( "background" ,UIConstants.GREY_LIGHT );
    UIManager.put( "controlDkShadow" , UIConstants.GREY_DARK );
    UIManager.put( "controlShadow", UIConstants.GREY_MIDDLE );
    UIManager.put( "desktop", UIConstants.BLUE_MIDDLE );
    UIManager.put( "menu", UIConstants.GREY_LIGHT );
    UIManager.put( "nimbusBorder", UIConstants.GREY_MIDDLE );
    UIManager.put( "nimbusSelection", UIConstants.BLUE_MIDDLE );
    UIManager.put( "textBackground", UIConstants.BLUE_LIGHT );
    UIManager.put( "textHighlight", UIConstants.BLUE_LIGHT );
    UIManager.put( "textInactiveText", UIConstants.GREY_MIDDLE );

    // panel
    UIManager.put( "Panel.background", UIConstants.GREY_LIGHT );
    UIManager.put( "Panel.disabled", UIConstants.GREY_LIGHT );
    UIManager.put( "Panel.font", UIConstants.DEFAULT_FONT );
    UIManager.put( "Panel.opaque", true );

    // button
    UIManager.put( "Button.background", UIConstants.GREY_LIGHT );
    UIManager.put( "Button.disabled", UIConstants.GREY_LIGHT );
    UIManager.put( "Button.disabledText", UIConstants.BLUE_MIDDLE );
    UIManager.put( "Button.font", UIConstants.DEFAULT_FONT );

    // menu
    UIManager.put( "Menu.background", UIConstants.GREY_LIGHT );
    UIManager.put( "Menu.disabled", UIConstants.GREY_LIGHT );
    UIManager.put( "Menu.disabledText", UIConstants.GREY_DARK );
    UIManager.put( "Menu.font", UIConstants.MENU_FONT );
    UIManager.put( "Menu.foreground", UIConstants.BLACK );
    UIManager.put( "Menu[Disabled].textForeground",
            UIConstants.GREY_MIDDLE );
    UIManager.put( "Menu[Enabled].textForeground", UIConstants.BLACK );
    UIManager.put( "MenuBar.background", UIConstants.GREY_LIGHT );
    UIManager.put( "MenuBar.disabled", UIConstants.GREY_LIGHT );
    UIManager.put( "MenuBar.font", UIConstants.MENU_FONT );
    UIManager.put( "MenuBar:Menu[Disabled].textForeground",
            UIConstants.GREY_MIDDLE );
    UIManager.put( "MenuBar:Menu[Enabled].textForeground",
            UIConstants.BLACK );
    UIManager.put( "MenuItem.background", UIConstants.GREY_LIGHT );
    UIManager.put( "MenuItem.disabled", UIConstants.GREY_LIGHT );
    UIManager.put( "MenuItem.disabledText", UIConstants.GREY_MIDDLE );
    UIManager.put( "MenuItem.font", UIConstants.MENU_FONT );
    UIManager.put( "MenuItem.foreground", UIConstants.BLACK );
    UIManager.put( "MenuItem[Disabled].textForeground",
            UIConstants.GREY_MIDDLE );
    UIManager.put( "MenuItem[Enabled].textForeground",
            UIConstants.BLACK );

    // tree
    UIManager.put( "Tree.background", UIConstants.BLACK );      
}

UIConstants中常量的数据类型是Color of Font的类型,具体取决于要设置的属性.

问题是,只有少数看起来和感觉选择改变.树的背景等选项不会根据外观和选项上的选项而改变.感觉.我知道这一点,如果我改变组件的画家,一些事情只会改变.但是例如JPanel没有这样的画家属性,但也有问题.

关于外观和问题,我有第二个问题.感觉：
不是例如画家menuBar应该使用在主色部分设置的颜色,还是我需要实现自己的画家才能使用？

有人能告诉我我的问题在哪里吗？

解决方法:

1.设置变化有点hacky,必须设置L& F,然后可以对L& F进行任何更改

伪代码

if( "Nimbus".equals( info.getName() ) ) {
   UIManager.setLookAndFeel(info.getClassName());
   UIManager.getLookAndFeelDefaults().put("Xxx", "Xxx")
   UIManager.getLookAndFeelDefaults().put("Xxx", "Xxx")
   break;
}

2.Font和部分颜色存储为XxxUIResources用于所有Swings L& Fs和XxxUIResources required another hack,

3.better可以使用@camickr的UIManager Defaults作为instaled方法的列表,而不是搜索到NimbusDefaults

4.about Painter,您可以设置自己的Painter(取决于UIDefaults中的类型或值)或覆盖XxxUIResources(取决于类型,有时,有些不起作用,因为Nimbus的开发在第二季度结束了somwhere),

编辑

5.Nothing better around,我认为@aephyr参与了Nimbus开发或e.i. ???
