Running two applications in the same Qt Creator instance

I am developing two apps that interact with each other over network.
They belong to the same subdirs project and I used to run them from the same instance of Qt Creator without any problems. E.g. I used the following usecases:
-
Run 1st app, then run 2nd app and see how they work
-
Debug 1st app, then run 2nd app
-
Debug 2nd app, then run 1st app
All three cases worked just fine in all versions of Creator I've ever worked with.
But in the Qt Creator 3.6.0 I see a different behaviour: the 1st app is immediately closed when I start the 2nd app. This is really inconvenient, is it a bug in Qt Creator?
Let me show on a simple example:
-
My simple sample project with two apps
-
When I am debugging the 1st app and press Run for 2nd app Qt Creator briefly shows this window, then 1st app is closed and 2nd is launched.
Is there a way to fix this? It used to work! Please help)

Hi,
That's a new feature in Qt Creator 3.6. Go to the Build & Run panel in Qt Creator's preferences, then in General you have a combo box beside "Stop applications before building". You can change there the behavior of that feature.

Thanks again, your solution totally works!I also posted this on SO: http://stackoverflow.com/questions/35002024/running-two-applications-in-qtcreator-3-6
Will be happy if you post your solution there! Or if you don't want to, I'll do it myself. I guess this can help other people as well :) -
You're welcome !
Since you can run your two applications again, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)

For me, your answer remedies a niggle I had with QtCreator for SailfishOS SDK.
I 'd build an application on my Sony mobile, at some point I require a larger image to see detail in my app, so I start up SFOS Emulator but found that starting the build on Emulator meant the phone app being stopped. I chose option 'None' in General Settings.
thanks!
