Hi, I get the following:
[EMAIL PROTECTED]:~/Controller/lib> python display.py UpdateStringProc should not be invoked for type font Aborted and I am back at the bash prompt - this is most frustrating, as there is no friendly traceback to help me guess where its coming from. And what is worse, the script runs for a varying time before it simply exits like this. What can I do to dig deeper to try to find a clue? - I don't even know if its Python, Tkinter or Linux... Some background: The application is a prototype gui for a controller of an injection moulding machine. It has two rows of five buttons across the top, and a canvas containing various objects over the rest of the screen. Extensive use is made of configure to change the text of the buttons, as well as their command bindings, to keep "the state of the system" current - its quite a hack at this time, as I am still experimenting with getting the interface intuitive. On the canvas, there are multiple instances of a Meter class to show things like temperatures and pressures, as well as a schematic representation of the machine, created out of polygons and lines. The schematic, as well as the Meters, are crudely animated by deleting and redrawing the objects repetitively with slightly different parameters in response to button presses. This is done by starting different threads to implement the various motions, which repetitively call kill and draw methods in the main app, after which they (the threads) commit seppoku by returning. Everything seems to work fine. - there is a thread that runs to move the meter values around continuously, and this has been stable for some time now, and I can get the various "machine" parts to move around the screen by pushing the buttons. The trouble occurs when I put the "machine" into Auto mode, simulating the various motions in a loop, - it runs for anything from a few tens to a few hundreds of cycles before handing in its dinner pail like this. Any Ideas on what to do next to find the culprit? - Hendrik -- http://mail.python.org/mailman/listinfo/python-list
