Add external program into existing qt application

[pauliedunne]

Hello, so I have an C++/SFML program running in Qt Creator that runs when I compile it, but I also have a Viewport created using Qt, I'd like to add my external program into the Viewport on a certain location. So when I click start on the Viewport, the external application will start up in the same window. Could anyone help me please?

It is not clear what you really want to do:

• Do you want to run C++/SFML program in its own process and control it through your viewport?
• Or do you want to integrate the C++/SFML into your viewport, so you only have one executable?
