I am a newbie to python, but not programming.
I have a menubar item
displaySubMenu.add_command(label=External, command=externalDisplay)
externalDisplay is a new class, which I have already imported. The class is
here:
from Tkinter import *
from datetime import datetime, date, time

I have the following chunk of code. Although it seems to execute fine, no
errors, the image is never resized. What am I missing?
imagePNG = Image.open(image.png)
photo = ImageTk.PhotoImage(imagePNG
canvasWidth = 300
canvasHeight

Not True! it contains syntax errors. Check the posted code and next
time post all the code.

I hope I can explain this correctly.
I have a GUI, which is already being processed by a mainloop. I want to be
able to open a second window so the user can interact with specific information
in the second window. I pulled together this code example
from Tkinter import *
class Net:
And I see now what I did wrong - thanks for putting up with the questions.

Here is the situation:
I have a window with a bunch of widgets in it. I want to clear the objects in
a given frame and recreate them to update them.
The example below destroys the top level frame, and so I can't recreate the
widgets. I am likely doing this wrong.

I should think it would work, but I don't understand why it doesn't.
Try
root.title(test)
title() is a method that you are hiding with your attribute leading to
problems later
I am having a problem getting around this variable namespace thing.
Consider these code bits
File a.py
from Tkinter import *
import a1
def doAgain():
x = a1.Net()
x.show(Again!)
root = Tk()
root.title(test)
f = Frame(root,bg=Yellow)
l = Button(root,text=window
Thanks to everyone for answering my question. I think its clear now. I'll
just go the stuff 'em in a module and import that route.

You need to check out the w.update
What I am trying to do is call a class function from a menu, for example
displaySubMenu.add_radiobutton(label=Medium,

No offense taken. I'll get getting the Google Python Style Guide today. I'll
package up the code tonight and it to the group. Fortunately ( or
unfortunately), it is all in one file right now.

Chris,
It looks as if you are calling a class
Oh and Risk,
I know I was calling the class object.
class 1 creates the instance object
class 2 tries to use the instance object
so the problem is how to make class 2 knowledgable of instance object? I guess
I could pass the instance object into the class, since class1 creates the
instance
Here is my chunk of code. I can't figure out what I am doing wrong to put my
scrollbar on the right hand side of the text box.
from Tkinter import *
def showLogFile():
top = Toplevel()
f = Frame(top, bd=0, bg=Gray)
top.title = netcomm log file
f.grid()
sc = Scrollbar(top)
Don't say cron :

I have an option menu
self.w = OptionMenu(self.frameNewNet, self.variable, one, two, three)
Is there a way to add items to this programmatically, i.e. using values from a
database?

I have a database query result (see code below). In PHP, I would have said
list(var1,var2,var) = $result
and each element in the list would be assigned to each of the named variables.
I have my data coming out of the database, and I can see it is a list. so my
question is, instead of
