Hi all, I'm debugging an existing application which uses Tkinter. Having not worked much with the library... please bear with me. In general, how is invocation of the event handler/dispatcher scheduled?
The application in question is a Tcl/Tk library written in C; a Python interface using Tkinter sits on top of it. It seems to start the main loop implicitly by creating a Tkinter.Tk object (is this true of how the loop gets started?). The underlying C library schedules a task to run at a set interval with Tcl_CreateTimerHandler(...). If I'm not running any code outside of this framework, all is good. However, if I run anything in Python-space (say, just a really long loop that prints numbers, for testing), invocation of the scheduled task is delayed until this other task is done. My questions then are: (1) Is this an inherit problem with how things in general are set up? Is everything running under a single thread? (2) If not, is it possible to bump up the priority of the Tcl/Tk main loop and have it preempt Python space more often (or at all!), or conversely, downgrade the priority of the Python space process? (3) If option 2 fails, are there other alternatives anyone can think of to have these two things co-operate? Thanks for your help. _______________________________________________ Tkinter-discuss mailing list Tkinter-discuss@python.org http://mail.python.org/mailman/listinfo/tkinter-discuss
