Difficult to say for sure due to excessive code wrapping.. ;)
but I would say that these bind methods are calling the left and right
Click methods... rather than bind'ing them to the entry widgets.
there are a few good ways around this, lambda, class with __call__ etc
etc most of these can be found with a little googling (in case this is
homework)

Anil,
Standard Tkinter widgets have a .children so for your frame widget
try printing the value of yourframe.children like so:-
Python 2.2.3 (#42, May 30 2003, 18:12:08) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.

Dean,
Look at the winfo_* methods of Tkinter widgets, I think the one you want
is called winfo_reqheight / winfo_reqwidth or something very similar
pydoc Tkinter.Canvas will sort that out

Sorry, I have not used py2exe for some time, you would be better to ask
this question on the py2exe list:

Pete,
Not sure but here is an example that seems to always work for me:
(tested this morning before pasting here on ~20 files around 7 - 300 k)
import ftplib
import os
os.chdir("D:/TEMP/dump")
ftp = ftplib.FTP("server")
print ftp.login("anonymous", "[EMAIL PROTECTED]")
ftp.cwd("pub/Python_Applications")
for rFile in ftp.nlst():
print "Getting : ", rFile
rSize = ftp.size(rFile)
lFile = open(rFile, "wb")
ftp.retrbinary("RETR %s" %rFile, lFile.write)
lSize = lFile.tell()
lFile.close()
if rSize==lSize:
print "Transfer complete"
else:
print "BAD Transfer", rSize, lSize
ftp.close()

Perhaps I am not understanding something... can you please show me an
example of what is not working. I consider the above a good recipe that
can be applied to any scrollable widget in Tkinter.
hmm, a single change to my example (Text to Frame) produces this
traceback:-
>C:/python24/python -u "quicksb.py"
Traceback (most recent call last):
File "quicksb.py", line 17, in ?
text['yscrollcommand'] = sb.set

self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: unknown option "-yscrollcommand"
>Exit code: 1
and another change (Frame to Label) produces this traceback:-
>C:/python24/python -u "quicksb.py"
Traceback (most recent call last):
File "quicksb.py", line 17, in ?
text['yscrollcommand'] = sb.set

This would suggest that the Frame and Label widgets are not scrollable
(at least not in the 'y' direction)

forget regular expressions for this job... strings have methods in
python so for example:
for line in file:
if line.startswith("#user_defined_variable = no"):
line.replace("#user_defined_variable = no",
"user_defined_variable = yes")
... continue processing file / writing out stuff as you go

The Menu Tk Widget has a delete or deletecommand method(s) the first
accepts an index the second a Menu label, both will remove the menu entry

I know you've found the answer to your question, however for the exact

I think the idea is you wait for the first call to subprocess.call to
finish before executing the second...
http://docs.python.org/lib/node231.html
call( *args, **kwargs)
Run command with arguments. *Wait for command to complete*, then
return the returncode attribute.
The arguments are the same as for the Popen constructor. Example:
retcode = call(["ls", "-l"])

Good.
Most 'problems' I have running this kind of system at home can be fixed
by adding your user account to the /etc/sudoers file like so:-
martin ALL=(ALL) ALL
so every now and then when I need to do somthing as root I just sudo
(and enter *my* password)
Linux distros such as ubuntu use this scheme and I think MAC OS X does
too.

Re-compile and or install wxPython as root, this will install it into a

I wonder if it is to do with the signature of these methods. they
accept two doubles and perhaps the python bindings do not automatically
convert from integers, therefore these methods are not called and the
rules of mro kick in (thus calling the python move method)

I think you want these two options to be in a cascading menu like so:
newmenu = Menu(filemenu)
filemenu.add_cascade(label="New...", menu=newmenu)
newmenu.add_command(label="Router")
newmenu.add_command(label="Firewall")

Re: tkinter text width
James Stroud wrote:
Hello All,
I would like for a tkinter text widget to be aware of how big the frame that
contains it is, then I would like for it to reset its width to the
appropriate number of characters when this frame changes size.
I can get a cget("width") for the text, but this does not dynamically reflect
the visible width.
One way I can think of is getting the size of the font used in the widget then
getting the width of the frame with cget then doing the appropriate math and
configuring the text widget upon resize events.
I'm thinking that there must be a more straightforward way.
Any ideas?
James
James,
Not sure I understand, do you want the text within the text widget to
wrap or change font so it fits? In any case to get a widgets width you
will need to look at the winfo_* methods for that widget
pydoc Tkinter.Frame
| winfo_height(self)
| Return height of this widget.
|
| winfo_reqheight(self)
| Return requested height of this widget.
|
| winfo_reqwidth(self)
| Return requested width of this widget.
| winfo_width(self)
| Return the width of this widget.
|
If you do want the text to wrap there is the option to do this when you
create the instance of the text widget:-
text = Text(root, wrap = "word") # word, char or none
text.pack()
Cheers
Martin

I'm not sure I follow your code but this method is bound to the

does not pass that event on to the default event handler.
def changed(self, ev):
w, h = self.winfo_reqwidth(), self.winfo_reqheight()
cfg = {}
if ev.height > h:
cfg['height'] = h

This may do what you want.

Pete,
pydoc Tkinter.Listbox
| curselection(self)
| Return list of indices of currently selected item.
|
| delete(self, first, last=None)
| Delete items from FIRST to LAST (not included).

| get(self, first, last=None)

So to get the value of the selected item:
lb.get(lb.curselection()[0])
provided the listbox is in single selection mode or only one item is
selected
Martin
Thanks Martin,
I used the:
lb.get(lb.curselection()[0])
ant this works to a point. When I select the item in the listbox the system
generates an error:
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__
return self.func(*args)
File "/home/linux/programming/dxcluster/servers.py", line 37, in sel
items = self.listbox.get(self.listbox.curselection()[0])
IndexError: tuple index out of range
Then if I select a second time directly after the error message I get my
desired result.
Pete,
Sounds like you are using the wrong kind of bind event. That is the
first time you select an item the callback for the bind command is
called *before* the selection is made. Can you post the code you have
showing the bind method and callback?
This code shows three different bind methods, the first produces the
same exception that you got...
from Tkinter import *
root = Tk()
lb = Listbox(root)
lb.insert(0, "one")
lb.insert(0, "two")
lb.insert(0, "three")
lb.pack()
def callback(*event):
print lb.get(lb.curselection()[0])
## BAD
#~ lb.bind("<1>", callback)
## OK
#~ lb.bind("", callback)
## Best
lb.bind("<>", callback)
root.mainloop()
The <> is a virtual event I think quick google would tell
you more and the Tk man pages (online) have a complete explanation...

Unfortunately, I see no way to collect stdout or stderr from the spawned process, so I can't tell what's going wrong. The "ssh remotehost PATH=$PATH nice -20 make ..." command works fine from a similar shell script. Thx, Skip Skip, While not a 'real' answer - I use pexpect to automate my ssh scripts these days as I had a few problems using ssh with the os.* family perhaps you may find pexpect a wee bit easier...

Re: tkinter socket client ?

Hi,
thanks for this info - I had to abandon the createfilehandler() method
as it is not supported in windows and the GUI "might" be used there at
some time ...
So - I went the threading route - works well - for now - so I will
stick to it ...
BUT - the next question:
In the Text() widget - why - when the text scrolls off the screen -
does the window not follow it ?
I have added a scrollbar to it :
self.center_frame = Frame(self.top_frame, background="tan",
relief=RIDGE)
self.text=Text(self.center_frame,background='white')
scroll=Scrollbar(self.center_frame)
self.text.configure(yscrollcommand=scroll.set)
self.text.pack(side=LEFT, fill=BOTH, expand=YES)
scroll.pack(side=RIGHT,fill=Y)
self.center_frame.pack(side=RIGHT, expand=YES, fill=BOTH)
but the window does not scroll to follow the text ?
Any ideas ?
This is the default behavior of the Text widget. You have two options
(as I see it) one, put the new text at the top of the Text widget
textwidget.insert(0, "your new text") or two, use the yview_pickplace
method to move the view down every time you insert text
textwidget.yview_pickplace('end')
I wrote a sub-class of the ScrolledText widget to do just this
I gave it a write method - so I could re-direct stdout to it - and also
called yview_pickplace in that method.
HTH
Martin.

Aprameya Hi, I was looking for this just yesterday... I 'found' a pure python samba client package here:- http://miketeo.net/projects/pysmb/ It seems to work too! I also found, but did not look into further, python bindings in the samba source code tree http://www.samba.org/ Regards Martin -- http://mail.python.org/mailman/listinfo/python-list
