未显示eclipse rcp树查看器的子节点

标签： eclipse eclipse-plugin eclipse-rcp rcp treeviewer

我在RCP应用程序的项目资源管理器视图中有一个树查看器。我的产品完全处理资源中的加载，值检索和更新值（“org.eclipse.emf.ecore.resource.Resource”）。我有一个创建项目菜单项，用于创建新项目。项目创建操作后，将在项目文件夹中创建一个新文件。我有一个标准文件，我需要在创建项目时加载它。因此，在整个应用程序中，我处理2个文件（标准文件和项目创建操作期间创建的文件）。当我在eclipse中运行rcp产品时，它工作正常，在项目创建过程完成后，项目节点出现在树中，当我尝试展开项目节点时，它显示子节点。

我尝试将其导出为eclipse产品文件中的rcp产品。当我尝试创建项目时，项目节点显示在树查看器中，但是当我尝试展开项目节点时，它下面没有显示任何内容。为什么不显示项目节点的子节点。子节点应该从项目创建过程中创建的文件中获取。 Th文件在项目文件夹中完美创建。我认为，这是由于与资源相关的一些问题而发生的。在出口产品时，我们是否应该关注资源。

我有同样的问题，虽然丑陋的这个课程。

这是一个ui资源未设置的问题，您还需要此扩展点“org.eclipse.ui.navigator.viewer”来创建具有项目资源管理器视图ID的查看器。希望有所帮助。
