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
import u
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

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:
d
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.
should I be doing this in a

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 1",command=
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.

What I am trying to do is call a class function from a menu, for example
displaySubMenu.add_radiobutton(label="Medium",
variable=radarPanelSize, command=radarWidgets.refresh)
class radarWidgets:
def __init__(self,root):
self.window = root
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.

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 and
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 want to have a section of my code executed at 15 minute intervals. I am
using Threading.timer, but it is causing a problem sinxe I am using sqlite3 and
the thread support gives me an error, which aborts part of my code.
So, is there an alternative to threading.timer?
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 having

The scenario is this:
I want to loop around all of the images in a given directory (which I know will
be images, but I guess I should check), show an image in a window, wait 2
seconds and show the next one and repeat that indefinitley, which will be until
the user closes the window.
This is th

I want to add a "Windows" menu item to my menu bar, so when another Toplevel
window is opened, I can add that to the menu bar in case the user accidentally
clicks on a different window and moves the Toplevel under something else.
Then when the window is closed, remove the window from the menu
I have some code that pulls a value from a database. In this case, it is three

text has curly braces around it, even when there are none in the surrounding
the text in the database.
Is this normal, and how do I pr
