Dynamic Data Exchange (DDE)

If this is the wrong forum for this question, my apologies.

I have Qt v4.6.4 and am looking for methods to add DDE functionality into my Qt QMainWindow application.
Just wanting to associate my own file types and have them launch in my app is all i need.
Does Qt have it's own methods for handling this?
Or, do I still have to use all Windows API calls?

thanks

Not sure what exactly you are looking for, did you look at QDesktopServices
