From: Alex Hall on 23 Mar 2010 13:01 Hi all, but mainly Tim Golden: Tim, I am using your wonderful message loop for keyboard input, the one on your site that you pointed me to a few months ago. It has been working perfectly as long as I had only one dictionary of keys mapping to one dictionary of functions, but now I want two of each. My program has different modes, which may have varying keystrokes, and I also have some global keystrokes which are the same across all modes, like exiting or switching modes. I cannot figure out how to make the message loop look in two dictionaries at onc. I tried using an if, saying that if action_to_take was not set in the mode-specific dictionary then look at the global dictionary, but it is like it is never looking in the global dictionary at all. I get no syntax errors or problems when running the program, so it has to be something in my logic. Go to http://www.gateway2somewhere.com/sw/main.pyw to see what I mean; the problem code is near the very bottom of the file. Thanks for any suggestions. Oh, please note that I indent one space per indentation level. -- Have a great day, Alex (msg sent from GMail website) mehgcap(a)gmail.com; http://www.facebook.com/mehgcap

Incidentally, you might want to change: if(not action_to_take): to: if action_to_take is None: in case any of the values happen to be 0 (if not now, then possibly at some time in the future).

I originally used 1-4 like I did for the mode dictionaries, not realizing that the ints were so important; I figured they were just keys in the dictionary and that they could be anything, it was just easier to use ints. Now, I have changed my globals to 20-23 and everything seems to be going well.

Sorry, could you explain why you suggested this? I do not follow. Because of the if statement "if action_to_take:", I figured it was saying "if action_to_take was successfully set" or something else having a boolean value.
