Hello Mr. Gauld, Your second guess about the scenario is right: I want to automate tests of Tcl/Tk GUIs. I know about the GUI test automation tools like WATSUP, PyWinAuto, winGuiAuto etc., and will use one if necessary. But test automation is usually easier at the lowest possible level for the test target (as per your suggestion to test the back-end functions directly). In this case, my test target is the Tcl/Tk GUI itself.
The Tcl/Tk functions I mentioned (Tcl_QueueEvent etc.) are listed in my copy of the Tcl/Tk Man pages (downloadable from www.tcl.tk/man). I believe they are C or C++ functions. Thanks for the explanation of what Tkinter does and doesn't cover. Is there another Python module that does include Python wrappers for Tcl/Tk C functions? My first glance at send() and event_generate() gave me the idea they were for other purposes. Your suggestion triggered a second glance; maybe event_generate can do what I need. I'll study it some more. Thanks for the clues - Dan K.
