I am currently reading An Intro to Tkinter (1999) by F. Lundh. This doc
was published in 1999 and I wonder if there is a more recent version.
I've googled a bit and this version is the one I keep finding. I like
how this document is organized and also how it provides the code with
visuals of what should appear on the screen. If there are other docs I
should read, please let me know.
Second, I am trying to work through a couple of the examples and make
some small tweaks as I go to see how new things can work. In the first
case, I have copied the code in the book to see how the menu works and
are created as in the example menu.py below. I see how menus are created
and how the command option is used to call the function callback.
from Tkinter import *
print "called the callback!"
root = Tk()
# create a menu
menu = Menu(root)
filemenu = Menu(menu)
helpmenu = Menu(menu)
However, I now want to incorporate a basic python program with a
command. Say I have a simple program called test.py
filename = raw_input("Please enter the file you want to open: ")
new_file = raw_input("Save the output file as: ")
f = open(new_file, 'w')
new = open(filename, 'r')
for line in new:
x = line.split('\t')
print >> f, x,':', x
To make this example complete assume I have a text file like this
So, the user currently just follows directions on the screen, enters the
file names, and I get what I want. I'd like to try experimenting with
gui programming to see if the python programs I have written can be made
even more user friendly. I currently use py2exe to create executables so
that others in my organization can use these programs.
In that spirit, say I want to have a menu option that allows the user to
search their computer for this file, execute the python code and then
save the result as a user-defined filename. So, I guess my questions are
how do I associate the portion of code in menu.py
"filemenu.add_command(label="Open...", command=callback)" with an
operation that gives the user the ability to search the drives on their
machine and then once they do let python execute the code in test.py?
