title: Ungrouping Separate Processes From The Taskbar
body: <p>I'm writing an application using C++ and Qt which the user can run multiple instances of on the same machine. Each instance of the application has two to three windows associated with them. At the moment, all instances of the application and their windows are grouped together in the taskbar (top image). I want each process to have its own group in the taskbar (bottom image). How can this be achieved?</p>
