how can i debug two applications (one using the other) simultaneosuly in qt creator?

how can two exectuable be debugged simultaneously? I mean, there are two app main_app and support_app. main app uses(call) support_app. i need to set break points on both the app (or one app and another dll)and see if main_app sends right data to support_app by moving from one break point to another.

in visual studio, it is done by adding both the app (projects) to one solution and settting break point on both. how this can be done in qt creator in linux/mac?
if not possible in qt creator, can it be done using eclipse and xcode as these IDEs available for linux and mac?

thanks in advance...

I think starting one more instance of Qt Creator with the other app will do the trick? :)

I haven't tried this, but you can open multiple projects at once in Qt-Creator. Maybe you can debug them both at the same time too.
