I've recently delved into Tkinter, and am trying to develop a simple notepad. The only problem s that it has problem saving files. Here's my code for saving:

CODE:	Copy / Restore :: Remove Scroll Bars
def filesave(): # save file try: openfile = open("external file.txt", "w") openfile.write(getAllText()) openfile.close() except: showwarning("Error saving file", "Cannot save file (%s)" % filename) # open file and save text field contents

And here's the code to select what you want to save the file as:

CODE:	Copy / Restore :: Remove Scroll Bars
def filesaveas(): # save file as... try: asksaveasfilename(filetypes=formats, title="Save As...") except: showwarning("Error saving file", "Cannot save file (%s)" % filename) # save file as specified type

But both return an error message and don't save. Any idea why this might be?

Thanks for any help,
-Mike

Doesn't tkinter's (never even heard of it) exceptions carry information? in PHP you can throw exception objects that carry the file and line number where it occured as well as a programmer defined text and an error code. In C++ you have to throw any kind of value (e.g. an integer). Isn't there something alike in tkinter?

I don't think so, but I did manage to fix it. However, I have run into another problem: Whenever I click "Save", no matter what, it takes me to the "Save As..." function; even if the file is already set. Here's my 2 new functions:

CODE:

Copy / Restore

filename = "Untitled"
# this is the filename that we start with
def filesave():
# save file
if filename == "Untitled":
filesaveas()
else:
openfile = open(filename, "w")
openfile.write(app.text.get(1.0, END))
openfile.close()
setTitle(filename)
# open file and save text field contents
def filesaveas():
# save file as...
filename = asksaveasfilename(filetypes=formats, title="Save As...")
if not (filename == ""):
openfile = open(filename, "w")
openfile.write(app.text.get(1.0, END))
openfile.close()
setTitle(filename)
# save file as specified type

If anyone wants to see the whole source code just ask. Any help would be greatly appreciated!

Again I can only make guesses. This time: scope/variable visibility problems.

That seems to be the problem. I checked and traced "filename" whenever the user (me :P) saves, and "filename" doesn't change. It stays as "Untitled".

Cheers,
