如何在Eclipse中获取当前所选文件的路径？ [英] How to get the Path of current selected file in Eclipse?

问题描述

我想在Eclipse工作区中获取当前所选文件的路径，但我的项目是一个简单的视图插件项目。

I want to get the path of current selected file in Eclipse workspace but my project is a simple view plug-in project.

我只想在用户打开视图后立即显示所选文件的名称/路径。

I just want to display the name/path of the file selected as soon as user opens the view.

推荐答案

@Danail Nachev提到的选择。请参阅 http://www.eclipse.org/articles/Article-WorkbenchSelections/article。 html 了解有关选择服务的信息。

You get the current selection as mentioned by @Danail Nachev. See http://www.eclipse.org/articles/Article-WorkbenchSelections/article.html for information on working with the selection service.

一旦你有选择，最常见的模式是：

Once you have the selection, the most common pattern is:

    if (selection instanceof IStructuredSelection) {
        IStructuredSelection ssel = (IStructuredSelection) selection;
        Object obj = ssel.getFirstElement();
        IFile file = (IFile) Platform.getAdapterManager().getAdapter(obj,
                IFile.class);
        if (file == null) {
            if (obj instanceof IAdaptable) {
                file = (IFile) ((IAdaptable) obj).getAdapter(IFile.class);
            }
        }
        if (file != null) {
            // do something
        }
    }

编辑：

通常你得到一个 InputStream 从 IFile 并以这种方式进行处理。使用一些FileSystemProviders或EFS实现，文件可能没有本地路径。

Usually you get an InputStream from the IFile and process it that way. Using some FileSystemProviders or EFS implementations, there might not be a local path to the file.
