GWT2 CssResource how to
GWT2 CssResource how to
提问于 2009-11-09 23:13:12
我有一个GWT1.7应用程序，我想把它升级到GWT2里程碑2。这个应用程序使用两个很大的外部CSS文件。在GWT1.7中，我有一个公共文件夹，并将CSS文件都放在该文件夹中，我的应用程序编译后运行良好。现在，对于GWT2，我已经创建了一个ResourceBundle类，并将所有的图像精灵和CSS放在下面：
public interface ResourceBundle extends ClientBundle {
public static final ResourceBundle INSTANCE = GWT.create(ResourceBundle.class);
@Source("com/web/tech/public/stylesheet1.css")
public Css stylesheet1();
@Source("com/web/tech/public/stylesheet2.css")
public Css stylesheet2();
@Source("com/docobo/keswick/keswickweb/public/images/organisnew.gif")
public ImageResource add_org();
.....
}Css类是一个扩展CssResource的空类：
public interface Css extends CssResource{
}然后在我的onModuleLoad()中我使用：
StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet1().getText());
StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet2().getText());当我编译时，我得到以下错误：
Rebinding com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle
Invoking <generate-with class='com.google.gwt.resources.rebind.context.InlineClientBundleGenerator'/>
Creating assignment for gxt_gray()
Replacing CSS class names
[ERROR] The following unobfuscated classes were present in a strict CssResource:
[ERROR] x-tab-scroller-left
[ERROR] x-tab-strip-disabled
[ERROR] ......loads of other styles
Fix by adding String accessor method(s) to the CssResource interface for obfuscated classes, or using an @external declaration for unobfuscated classes.按照上面的说明，当我在CSS文件中的所有样式类中使用@external时，我得到了以下错误：
[ERROR] Generator 'com.google.gwt.resources.rebind.context.InlineClientBundleGenerator' threw threw an exception while rebinding 'com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle'

尝试使用@NotStrict。示例：
@NotStrict
@Source("com/web/tech/public/stylesheet1.css")
public Css stylesheet1();Stack Overflow用户

把它解决了。正如Thomas@Google Groups -->指出的那样，不能将@external放在样式之上
http://code.google.com/p/google-web-toolkit/wiki/CssResource#External...
此链接中的示例css将如下所示：
@external .legacySelectorA, .legacySelectorB;
.obfuscated .legacySelectorA { .... }
.obfuscated .legacySelectorB { .... }
/* @external also accepts tail-globs */
@external .myProject-*;
.myProject-text {}
.myProject-foo {}页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
