Hello,
My first attenpt at a simple python Tkinter application. I wanted to
see how to load file names into a listbox from a menu. This is what I
got until the part of displaying the file names in a listbox, which I
could not figfure out how to do?
Any help would be appreciated. Trying to do this as simple as possible
to understand.
The print fileNames does work but how to display it in listbox?
from Tkinter import *
from tkFileDialog import askopenfilenames
class MyCode:
def __init__(self):
root = Tk()
menubar = Menu(root)
filemenu = Menu(menubar)
lbox = Listbox(root, width=50).pack()
Your problem is the above line of code.
Here you are assigning the return value of the pack (None if I recall).
Later when you want to put things in the Listbox you don't have the
widget reference anymore.
It's probably a good idea to make the Listbox widget an attribute of
your class so you can use it in class methods without having to pass it
as an argument.
So, change the above line of code to:
self.lbox = Listbox(root, width=50)
self.lbox.pack()
menubar.add_cascade(label='File', menu=filemenu)
filemenu.add_command(label='New Project')
filemenu.add_command(label='Load Files...', command=self.OnLoad)
filemenu.add_command(label='Exit', command=root.quit)
root.config(menu=menubar)
root.mainloop()
def OnLoad(self):
fileNames = askopenfilenames(filetypes=[('Split Files', '*')])
print fileNames
Now that you've got a reference to your Listbox widget that is an
attribute of your class, you should be able to insert the file names
into the Listbox like so.
self.lbox.insert(0, fileNames)

Thank you John for your reply.
I have made the modifications and it does print inside the listbox,
however they are all printed on the same line.
My files are named Name.0 Name.1 Name.2 Name.3 etc so I would like
them to be printed sorted on a separate line. When I did a
type(fileNames) it showed me that it was in unicode and printed
character per line, so I tried it this way
listFileNames = str(fileNames).split(' ')
for fileName in listFileNames:
self.lbox.insert(0, fileName)
it works but does not print sorted.
it prints
name.2
name.1
name.0
name.3
Thank you for all your help.

Sorry, I didn't realize askopenfilenames returned the filenames as a
whitespace separated string, on my system they are returned as a tuple
of strings.

You obviously need to sort the list before you loop over the items and
add them to your listbox.
listFileNames = sorted(str(filenames).split()
