To avoid issues with Qt (mainly thread safety) and the need for 3+ screens, I am typically using two apps - one OSG-based, to render the simulation and another one with Qt, running on a separate machine to control it. They were talking to each other using CORBA (RPC). I am using OmniORB for that part, it is fairly easy to use. CORBA/networking may sound like an overkill, but it lets you have your control GUI on another machine while the main machine drives the simulation and may be inaccessible (e.g. back projected wall driven from some back room like in my case). The ability to keep the control GUI in front of the screen on a separate computer is great then. Regards, Jan
