我刚刚安装了 JCL 和 JVCL 库，主要是因为它们包含替换旧 rxLib 组件的组件，并且我正在升级一个大量使用这些组件的旧项目。
我现在发现我的 Delphi 2010 IDE 中有许多新选项卡，但没有提示（除了组件名称）这些组件的用途。 TJvEdit 与 TEdit 有何不同？什么是 TJvSpecialImage？
检查 JVCL 帮助目录和谷歌搜索甚至无法找到库中包含的组件列表。有谁知道这样的文件是否存在？
编辑后续问题：
现在 Lars 向我展示了从哪里下载帮助文件，但我无法将它们安装在 Delphi 帮助系统中。显然，我应该使用 Delphi 提供的 h2reg 实用程序来应用文件（我假设使用 JVCL333_h2reg.ini 文件来驱动该进程），但我能找到的唯一提示是这样做会导致损坏通过不正确的操作来帮助系统。
（注：我本机上也安装了D2007，但只想安装D2010中的帮助文件）。
I've just installed the JCL and JVCL libraries, mostly because they contain components replacing the old rxLib components and I'm upgrading an old project that made heavy use of those components.
I now find myself with numerous new tabs in my Delphi 2010 IDE, but no hint (beyond the component names) of what these components do. How does TJvEdit differ from TEdit? What is TJvSpecialImage?
Examination of the JVCL help directory and a google search has not been able to find even so much as a list of components included in the library. Does anyone know if such a document exists?
Edit, Follow-Up Question:
Now that Lars showed me where to download the help files from, I can't get them installed in the Delphi help system. Obviously, I'm supposed to use the h2reg utility supplied with Delphi to apply the files (with the JVCL333_h2reg.ini file to drive the process, I assume), but the only hints I can find on doing this stress the danger of corrupting the help system by doing it incorrectly.
(Note: I also have D2007 installed on this machine, but only want to install the help file in D2010).

你的安装没有附带帮助吗？好吧，您可以在这里找到它： http://sourceforge.net/projects /jvcl/files/JVCL%20Help%20Files/ 或使用 http:// help.delphi-jedi.org/
您可以在 http://help.delphi-jedi.org/browse.php?Id=12&types=1。离线帮助中包含类似的列表。似乎还没有每个部分都被记录下来。这可能是使用开源所要付出的代价。
Didn't your installation come with Help? Well, you can find it here: http://sourceforge.net/projects/jvcl/files/JVCL%20Help%20Files/ or use the online help at http://help.delphi-jedi.org/
You can find a list of the available types on http://help.delphi-jedi.org/browse.php?Id=12&types=1. A similar list is included in the offline help. Not every part seems to be documented yet. That might be the price to pay for using open source.

It is very good to contribute a bug report at http://issuetracker.delphi-jedi.org/my_view_page.php about the Mega Demo not working (compile failed) in delphi 2010.
