How to view hierarchical package structure in Eclipse package explorer

问题

OK here\'s what I would like: in the Eclipse package explorer, I see the following: (dot represents a clickable arrow that I can use to expand the folder)

• PROJECT
  • Source Folder
    • Package
      Class
    • Package.SubPackage
      Foo
      Bar
    • Package.OtherSubPackage
    • Package.OtherSubPackage.VerySubPackage
    • OtherPackage
      Foobar
    • OtherPackage.SubPackage
      Baz

Long story short, I want to have many packages, each with many subpackages, in a source folder (and several source folders, so making more won\'t solve the problem)--so on the order of a couple hundred packages per source folder--ten to twenty packages each with fifteen subpackages. Therefore, I want the hierarchy to look like this:

• PROJECT
  • Source Folder
    • Package
      Class
      • Package.SubPackage
        Foo
        Bar
      • Package.OtherSubPackage
        • Package.OtherSubPackage.VerySubPackage
    • OtherPackage
      Foobar
      • OtherPackage.SubPackage
        Baz

so I can open or close a package and see a list of subpackages instead of having package and subpackage all at the same level in the hierarchy--which again makes far too many packages simultaneously displayed. Note this is not a question about filesystem; the file system works fine as far as I can tell--it is only a question about the visual display in the Eclipse package explorer.

So: is there a way to add levels to the hierarchy? Thanks!! (Eclipse Helios on OS X 10.6)

回答1:

Package Explorer / View Menu / Package Presentation... / Hierarchical

The "View Menu" can be opened with Ctrl + F10, or the small arrow-down icon in the top-right corner of the Package Explorer.
