Using TK and the canvas.

Hi all. I'm experimenting with making a UI for a little (well, not
quite) script that basically draws up a tech tree to some skills from
my favorite game. What I'm aiming for looks a little like this site
hereapologies if I'm not supposed to direct link)
http://www.anderkoo.com/uploads/271/605/NewTechTree.jpg.

Anyway, I made a script which reads data from several files and saves
the data into an array of skill objects, here's what it looks like:

#define the class
class skill:
def __init__(self, name, description, a1, a2, rank, prereq):
self.name = name #string (example is "Anchoring")
self.desc = description #string (example is "blah blah blah")
self.a1 = a1 #string with attributes affecting the skill
(Example is "Int")
self.a2 = a2 #string
self.rank = rank #how hard it is to train (example is "5")
(too lazy to convert to int
self.prereq = prereq #any prerequsites (an array of ["skill",
"levelrequired"])

#the trained level already
self.skillowned = "0" #we change this later on when we access
another file

Finally, I set up a class which accepts a parent (normally root), and
the skill in question.
here it is:

class SkillInfo:
def __init__(self, parent, skill):
container = Frame(parent)
container.pack()

#we make this the top frame for some reason
labelcontainer = Frame(container, height=50, width=50)
labelcontainer.pack(side=LEFT, fill=BOTH, expand=YES)

desccont = Frame(container, height=50, width=50) #the
description content
desccont.pack(side=LEFT, fill=BOTH, expand=YES)

#make a name label
Label(labelcontainer, text=skill.name, wraplength=100).pack
(side=TOP, anchor=W)

#print the level buttons
for i in range(1, 6):
button = Button(labelcontainer)
button["text"] = "Level", i
if int(skill.skillowned) >= i:
button["background"] = "green"
button["width"] = 10
else:
button["background"] = "red"
button["width"] = 10
button.pack(anchor=W)

Label(desccont, text=("\n"+skill.desc), wraplength=100).pack()

Now I know all I have to do is set the SkillInfos parent to a canvas,
but how would I arrange and draw the lines? Thanks all

You should really check out wxPython, there is support for just this
type of thing. of course you could do this with Tkinter, but just
thinking about it makes my head hurt .

Alright, I shall investigate. Thank you.
