Hello, I'm learning Tkinter, and I have an issue that I'd appreciate help with. I have a program that initializes a GUI (I'll call this the "GUI process"), then spawns another process that listens on a network via the TCP/IP protocol for incoming strings (I'll call this the "server process"). Everything works well up to this point.
What I want to happen next is for the server process to update a label in the GUI process when it receives a message from the network. First I tried passing a control variable for the label's text into the server process, but when I updated the control variable, nothing happened(no error messages, no feedback of any kind). I tried piping the message from the server process into the GUI process using os.write() and os.read() - and this works, but not the way I need it to. I need the label to be updated automatically, without any intervention from the user (at the moment, it only works when the user clicks an "Update" button). I tried having the GUI process check the pipe for messages automatically, but when I do this it hangs when there's nothing in the pipe. I've tried other avenues as well, but probably nothing worth mentioning. If you have any suggestions, I would be very grateful. -- http://mail.python.org/mailman/listinfo/python-list
