Eclipse Plugin Development: Make plugin dependent on CDT-plugin

I am writing a plugin which I want to use the CDT-plugin (since I don't want to implement my own brand new C/C++ editor).

Questions:

• How is it possible to set the dependencies of my plugin to this particular editor
• How can I set this editor as a nature of this project?

Fro your first question, simply add the CDT plugins to your Required plug-ins of your project. Details here.

Editors and natures are different things, you cannot set an "editor as a nature". Probably what you're searching for is the C++ nature you want to set for a project programmatically. Simply search the nature's ID in the .project file of a C++ project, then you can start looking into the details.
