Add new extension to C++ plugin?
This ought to be simple, but I'm not seeing where/how to do it. I simply want to tell Qt Creator that filenames ending in ".doxy" should be treated as C++ files for editing purposes. The C++ editor preferences already know about "qdoc" files; it's just that I don't happen to be using qdoc.
Is there an easy way to do this, or is the knowledge of extensions buried deep in the source of Qt Creator?
You can set up the highlighting in Tools->Preferences->Text editor->Syntax Highlighting->Download Definitions...
But you are asking about the editor. That can be set up in Tools->Preferences->Environment->MIME Types.
