Anyone that's interested, I have a command line application which I want to run as such, with a flag that alternately puts up a pretty monitoring GUI that shows in more detail what's going on. So fine, I run the Tk mainloop in a background thread. I've read and learned myself you cannot make your Tk calls outside this thread. Fine.
But as this is a bit of an extra feature I have not been particularly careful, and since the command line can execute more than one sequence of it's processing, it wants to open up a new pair of windows every time. As I"m just hacking this together (the pretty Tk interface is an addition, not really required to be build) to do this I call the master object which is a threading object... i.e. another thread is started, and this other thread has a mainloop call in it. It all works fine, but I'm sort of of the impression I'm not supposed to do this, that there should only be one thread running a mainloop call. Is that true, is this evil? Any comments appreciated. craig
