Two problems...
1. WindowAdaptor is an abstract class.  You can't instantiate abstract classes.  Extend it instead.
2. KeyListener is an interface.  You can't instantiate interfaces.  Implement it instead.

Have Labyrinth extend WindowAdaptor and implements KeyListener.  Then override the WindowAdaptor methods you want and implements the KeyListener methods in some fashion.  Actually...you might want to make a separate class for the window this will exist in and just pass it the labyrinth.  Let the labyrinth worry about itself and the window worry about letting you see it.

Hard to believe this thread is almost up to a 100 pages.   :o

Here is a screenshot of something I've been working on.

Its a dungeon keeper style game done with libtcod and python.  I've got a lot of the infrastructure done, but I still need to work a lot on adding actual game mechanics, UI bits, content and AI.

Have Labyrinth extend WindowAdaptor and implements KeyListener.  NO! Absolutely no need to do this! Then override the WindowAdaptor methods you want and implements the KeyListener methods in some fashion.  Actually...you might want to make a separate class for the window this will exist in and just pass it the labyrinth.  Let the labyrinth worry about itself and the window worry about letting you see it. This is a very good idea.

Your WindowAdapter is fine, but you'll want your inner class to extend KeyAdapter instead of implement KeyListener.

Hey... new stupid question.

I want to take a dictionary and return the key that maps to the minimal value.  Any of y'all know how to do that with built-in functions?

Indeed.

I'm just wondering if there's some way to get the set of all keys mapping to a particular value, or something like that.

Hmm, apparently not. Or at least not built into python. Finding the key from a value is a rather strange way of doing things, like carrying around a lot of padlocks for random keys you have scattered about. I'm left to wonder why you need to...


Anyway, the first solution I found was a nice little function somebody made that should do what you need.
Code: [Select]
def find_key(dic, val):
    return [k for k, v in dic.iteritems() if v == val][0]
EDIT: Ok, fixed something. That will teach me to copy pasta the work of people who can't even make a working function.

I don't think there is an easy one liner, but I think this should do it:

Code: [Select]
dict = {'a': 1, 'b': 2, 'c': 1, 'd': 5}

keys = []
for key, value in dict.iteritems():
   if value == 1:   #change one to whatever you want it to be.
      keys.append(key)

Or if you wanted the minimum value, this:

Code: [Select]
dict = {'a': 1, 'b': 2, 'c': 1, 'd': 5}

keys = []
for key, value in dict.iteritems():
   if value == min(dict.items()[1]):
      keys.append(key)


In ruby, its much easier.  :D

Code: [Select]
list = dict.to_a.find_all{|a| a[1] == min(dict.values)}

Yeah, that was basically plan B.  I guess I'll get to that, then...

But no seriously, why are you looking for keys when you have a hand full of open locks?

Because I need the key pertaining to the minimal value, not the minimal value itself.

So, I opened up my IDE today in CompSci to try to figure out what was going so horribly wrong with inheritence in Gridworld. I glanced at the file and hit compile, just for kicks. And then... Nothing popped up.

Yes, that's right. Nothing. No errors. A clean compile. Literally overnight, the problem went away. It's still happening on my personal laptop, but not my school computer. Nothing was changed on the school computers that I know of. There is no reason for it to have suddenly started working. I'll post the code later when I'm less distracted by other things.

Like I said, sounds more like a glitch than lack of feature. You have to remember that the JVM is doing backflips to keep track of what exists when you don't have to forward declare everything, I guess something went wrong somewhere.
