Question

我使用示例邮件rcp应用程序来测试常见的导航框架。我添加了一个视图并将其附加到我的contentprovider。遗憾的是，在我的视图中没有显示任何内容，我的内容提供者或标签提供者的任何功能都没有被调用。

这是我的plugin.xml

   <extension
         id="application"
         point="org.eclipse.core.runtime.applications">

类TreeContentProvider和TreeLabelprovider存在并打印到控制台，如果它们被调用，它们不是。我做错了什么？

Answer 1

添加：

layout.addView("com.example.test", IPageLayout.RIGHT, 0.3f,IPageLayout.ID_PROJECT_EXPLORER);

在Perspective.java文件中。启动时使用标准透视图。您必须手动添加要在启动时看到的视图。

我已将您的代码与两个项目进行比较，但没有找到理由。我只能推荐你这两个教程，这对我非常有帮助： michael elder，Simon Zambrovski。

自己的RCP中的CommonNavigator - App没有显示任何内容
