How filecmp walk into subdirectories?
Hi Folks, I tried to compare two directories, each with hundreds of files in multiple level subdirectories, to find out the different files. I used filecmp module to the job as: comp=filecmp.dircmp(adir, bdir) comp.report() It worked, and printed out the identical and different files. However, it did not go through the directory trees, just did the job in the first level. I wonder somebody can help? Thanks in advance! Cosmo -- http://mail.python.org/mailman/listinfo/python-list
How to move scrollbar by code?
Hi Folks, I am trying to make a listbox that will contain a looong data list, sorted, so I will be able to pre-select a data line by coding. I have done it. Say my listbox contains 1000 data lines, and my program has figured out the data line 321 is needed, so just put the cursor on data line 321. However, my scrollbar is still seating on the top, so I just can view the data line from line 0 to 30 or 40, since I can't see the desired data line 321. I still need to manually pull the scrollbar down to display the data line 321. What I want to do is to grab the adjacent data lines, say from line 300 to 340, and display this lines, while my cursor seating in the middle. I consulted the Python Docs, but did not find such details. Can somebody give an idea? Thanks! Cosmo -- http://mail.python.org/mailman/listinfo/python-list
What is this widget?
Hi Folks, I am trying to write letters on a photo that is opened in a canvas. So I think I must need a widget to contain the letters I will type in. I tried to use a Label, it worked. But, a Label covered part of the photo underneath, so I can't use it. I saw some software did such a thing nicely: a box popped on a photo, with dotted lines as borders, expandable. When such a box was re-sized with a mouse, the font size in the box also got changed. The box has no background color, so it does not cover a rectangle area on the photo. I need such a widget, but I don't know what is this one. I tried Text, Label, but they all come with Window-like stuff, so they cover some photo content. Can somebody points me a direction? Thanks!

Hi Folks, Sorry for the unclear question in last post. Well, I am using Tkinter to do GUI, and I just don't know what kind of widget can let me do annotation on an image being displayed.

How to use a color value returned by colorChooser?
Hi Folks, This should be a simple question, but I just can't get an answer from Phython Docs. You see, when we created a widget, and need to tweak the color, we just simply configure it, such as: abutton = Button(root, text='Foo') abutton.config(fg='blue') so we can make the Button color in blue. However, when I choose a color by a color Dialog, askcolor, and then I will get a color value as: (0, 0, 255) . So, I want to use this returned color value to configure my existing widgets, with widget.config() syntax. The Python interpreter does not take it. Therefore, I think I must need to covert this returned color value into a symbolic name, such as 'blue', 'red' and so on, then the widget.config() syntax can be used. How can I convert this color value? Please help, thanks folks! Cosmo -- http://mail.python.org/mailman/listinfo/python-list
Why widgets become 'NoneType'?
Hi Folks,
I was driven nuts by this thing: widgets lost their attributes, then I
can't configure them. Please take a look at the codes below:
from Tkinter import *
canvas = Canvas(width=300, height=400, bg='white')
canvas.pack(expand=NO, fill=BOTH)
pic = PhotoImage(file=img)
canvas.create_image(0, 0, image=pic)
al = PhotoImage(file='a.gif')
lbl = Label(canvas, text=x, fg='red').pack(side=LEFT)
canvas.create_text(40,20, text='Howdy')
the last line of code got error message, says canvas object has no
attribute of config. The same problem happened again, the code is
below:
def make_labels(win, astr):
labels = []
for i in range(len(astr)):
lbl = Label(win, text=astr[i]).pack(side=LEFT )
labels.append(lbl)
return tuple(labels)
def config_labels(atuple, func):
for lbl in atuple:
lbl.config('%s') % func
root = Tk()
lbls = make_labels(root, 'foobar')
config_labels(lbls, "fg='red'")
The config for Label was picked up: No attributes of config. I tried
to print type(lbls), and found Python interpreter reported as
'NoneType'. I also tried to print out dir(lbls), fount there was no
attributes I familiar with such as config and such. What is wrong with
them? Both of the codes above WORKED, since I saw my widgets displayed
them as I wanted, but I just can't configure them as I usually did.
Can somebody help me out? I never experience such a weird thing.
Thanks!

How to execute a hyperlink?
Hi Folks,
Module os provides a means of running shell commands, such as:

os.system('dir .')

I think a hyperlink should also be executed. I tried:

Results of executing hyperlink in script
Hi Folks,
My previous post got a many helps from the people, and I tested what
they suggested. Since this topic maybe needed in future, so I drop
these lines below to help the future programmers. The methods worked
as below:
1. This method was suggested by Cameron Laird:
os.system("start %s" % URL)
It works. But, if the URL contains character &, it will fail. For
example, if URL has only one field, such as:
http://www.mydomain.com/ascript.cgi?user=muddy
this method works well. But, if there more than one field need to be
input, such as http://www.mydomain.com/ascript.cgi/user=muddy&password=foo,
the field password failed to reach server, and the CGI script
complained.
2. The best way is to use urllib2, suggested by Ron Barak, my code is
below:
import urllib2
source = urllib2.urlopen(URL).read()
print source
It successfully triggered CGI script, and also got feedback from
server. It works very well!
My thanks go to all the helpers!

How to trigger a smart link?
Hi All, Using urllib2 can trigger CGI script in server side. However, I encountered a problem of the so-called smart link. When a fairly large site, the server needs to track the identifier of each request from client, so it generated an ugly escape string attached on url. It seems that I must get this ugly escape string first then I can can fill the string into my url, and the CGI script on server side can be triggered. For example, http://whatever.com/submitreal.cgi?fp=3xD0TuGMp7C7gP1TRD displays a submit form. If I just copy http://whatever.com/submitreal.cgi to url address, without the escape string ?fp=3xD0TuGMp7C7gP1TRD, the browser will report error of 404 I found Python has a module of escape, but I don't know how to use this module to solve the problem above. Or, I just wonder does urllib2 has such a method to handle smart link? Thanks! Moddy Coder -- http://mail.python.org/mailman/listinfo/python-list
urllib2: problem of handling space in parameter
Hi Folks, I encrountered a problem of using urllib2: the space handling.

RE: Attaching C++ libraries to Python app.
I am just asking. In future I may need to import any C++ library, not a Crypto, but some other.

Working with PyQt and Pydev
I installed the PyDev plugin into Aptana Stdui 3 Beta. Someone suggested me to use PyQt for Python GUI app, and so I downloaded and installed PyQt. But when I open Aptana Studio, I could see a new menu added with the name "PyDev", but there is nothing for PyQt. In the Windows Start Meny item list, I could see a folder named PyQt and when I open it, there are few tools like Designer. When Designer is run, it opens Qt IDE for designing Forms like Visual Studio and the files have the extension .ui.I want to know how to integrate PyQt and PyDev. Do I need to use them separately by adding the .ui files to PyDev and then adding Python core code for functionality? ...Rohit.elementFontfont-familyfont-sizefont-stylefont-variantfont-weightletter-spacingline-heighttext-decorationtext-aligntext-indenttext-transformwhite-spaceword-spacingcolorBackgroundbg-attachmentbg-colorbg-imagebg-positionbg-repeatBoxwidthheightborder-topborder-rightborder-bottomborder-leftmarginpaddingmax-heightmin-heightmax-widthmin-widthoutline-coloroutline-styleoutline-widthPositioningpositiontopbottomrightleftfloatdisplayclearz-indexListlist-style-imagelist-style-typelist-style-positionTablevertical-alignborder-collapseborder-spacingcaption-sideempty-cellstable-layoutEffectstext-shadow-webkit-box-shadowborder-radiusOtheroverflowcursorvisibility -- http://mail.python.org/mailman/listinfo/python-list
