So... I've been tinkering with python and Tkinter and ttk a bit lately,
and because I've been using pylint which complains a lot if I do a
wildcard import like I see in many (most?) Tkinter tutorials i.e.
from Tkinter import *
from ttk import *
I've been trying to avoid doing wildcare imports, but I was finding that
if I imported in this form:
from Tkinter import Tk
from ttk import Frame, Label, Button, Entry
...that I started running into problems where my grid positioning info
started causing warnings that the variables 'S' and 'E' were not
defined. Here is an example line:
labelCel = Label(frame, text="Celsius temperature:")
labelCel.grid(row=1, column=1, sticky=(S, E))
labelFar = Label(frame, text="Fahrenheit temperature:")
labelFar.grid(row=2, column=1, sticky=(S, E))
Furthermore, when I did try to run the program, the python interpreter
objected as well and it crashed at the first undefined 'S'...
I dug around a little and found one resource that instead imported like
this:
import Tkinter as tk
and then the code would look like this:
labelCel = tk.Label(frame, text="Celsius temperature:")
labelCel.grid(row=1, column=1, sticky=(tk.S, tk.E))
labelFar = tk.Label(frame, text="Fahrenheit temperature:")
labelFar.grid(row=2, column=1, sticky=(tk.S, tk.E))
Which worked and is all well and good... if I didn't want ttk widgets
instead of Tkinter when possible.
Somewhere along the line I found yet another example/tutorial that
showed something like this:
from Tkinter import Tk, S, E
from ttk import Frame, Label, Button, Entry
which works with the original code example, but thats where I get
confused.
I have to import Label from ttk but the sticky parameters from Tkinter?
Pardon me for saying, but that doesn't appear to make a whole lot of
sense at first glance. Am I getting that correct, or is there some
other way to do it that is more correct?
I'm starting to think it'd just be easier to put some tags in comments
at the start of the file to tell pylint to disable warning me about
wildcard imports, and just go back to using those!
Thanks,
Monte
