Yes, and yes. You are missing multi-threading, which is the widely used approach to doing things simultaneously in a single process. In one thread, user interaction can occur; in another, computation. If you need non-blocking interaction between the threads, use queues, or other global variables. If you have other event sources, deal with them in separate threads. Yes, it is possible to get event loops with Tkinter. Atleast on Unix, you can install a file handler into the Tk event loop (through createfilehandler), which gives you callbacks whenever there is some activity on the files. Furthermore, it is possible to turn the event loop around, by doing dooneevent explicitly. In principle, it would also be possible to expose Tcl events and notifications in Tkinter (i.e. the Tcl_CreateEventSource/Tcl_WaitForEvent family of APIs). If you think this would help in your case, then contributions are welcome. > 2) Will Tkinter always be the standard toolkit for Python, or are there > plans to replace it at some point? Python does not evolve along a grand master plan. Instead, individual contributors propose specific modifications, e.g. through PEPs. I personally have no plan to replace Tkinter.
