Your posts are no doubt highly meritorious but I am afraid they are not offering much clarification. You would probably make your point better if you shortened your posts by roughly an order of magnitude. However, after cutting through the dense undergrowth, I still think you have failed to understand how programs using event loops work. If the program is not just running a single batch of instructions, it has to have a loop in there somewhere, which is blocking until there is something to process. The simplest loop for your console program would involve blocking on select() or poll(), for which purpose presumably you must have a file descriptor to poll on. In that case, as I said, you can do the same with Glib::signal_io().connect(). Or maybe you are polling using timeouts, in which case the equivalent for gtkmm is Glib::signal_timeout().connect(). Why not get to the heart of the matter, and post a short compilable console program, cut down from the ones which you appear to have written for monitoring VPNs, but of no more than 50 lines, and we can tell you how to do the same using a graphical interface.
