If you do this, import 'as tk'.

The second import overwrites the first since it imports tkinter.Tk as

You're either not running an X server, or having problems to connect to it.

Are you sure that Google Colab supports X11 at all? This link doesn't 
seem to support that idea:

staticmethods are essentially useless in Python.  What little was gained

The confusion is that methods are callable, whereas 'staticmethods' are 
not.  I was not completely aware of this until pointed out by Peter 
Otten with example


"cmd()

Indeed, dir(cmd) shows that it does not have a .__call__ attribute.

     cb=Checkbutton(command=cmd)


Button commands have to be tcl functions.  Tkinter wraps Python 
functions as tcl function.  Static methods also wrap python functions, 
as a .__func__ attribute.  So the code if one passes cmd.__func__.


"So the code works if one passes the callable cmd.__func__."

Maybe there is a bug in tkinter, that it doesn't work with static 
methods?

Command options, as documented, must be callables. Neither staticmethods 
nor classmethods are callable.



and unwrap them when they are.


 I would propose instead that if possible tkinter raise TypeError when 
passed a non-callable as a command.



Classmethods also do not work as is.  By experiment, the following works.
     cb=Checkbutton(command=lambda: C.cmd.__func__(C))
But if the class were nested, it would be more complicated.

After some experiments I found two solutions:

1)

class C:
@staticmethod
def cmd():
print("Test")
class C: #@DuplicatedSignature
from tkinter import Checkbutton
import tkinter

top=tkinter.Tk()
cb=Checkbutton(command=C.cmd)
cb.pack()

@staticmethod
def loop():
C.top.mainloop()

c=C()
c.loop()

2)

class C:
from tkinter import Checkbutton
import tkinter

@staticmethod
def cmd():
print("Test")

top=tkinter.Tk()
cb=Checkbutton(command=lambda : C.cmd())
cb.pack()

@staticmethod
def loop():
C.top.mainloop()

c=C()
c.loop()

This one as a sequence of the answer of Terry - thanks.

BTW, does anyone know I can I get the arguments eventually passed by the
Checkbutton event, or any other widget callback (*pargs, **kargs) using
this "solution"?

It depends on what the classes are being used for.
Sometimes I just want to use them as static wrappers.
Of course I could use them in the conventional way for this purpose, but
it's not so clean :-)

Why not just
cb=Checkbutton(command=lambda : C.cmd()) ?
Also works.
BTW, just for curiosity, and for my personal learning ... What does
"__func__" does?

It has nothing to do with tkinter, a staticmethod object cannot be
called directly:

>>> class C:
@staticmethod
def cmd(): print("Hello")
cmd()


Traceback (most recent call last):
  File "", line 1, in 
class C:
  File "", line 4, in C
cmd()
TypeError: 'staticmethod' object is not callable

You have to go through the descriptor protocol:

>>> class C:
@staticmethod
def cmd(): print("Hello")


>>> C.cmd()
Hello

I recommend that the OP use a more conventional stye and do the setup
outside the class or, better, in an instance of the class.

staticmethods are essentially useless in Python.  What little was gained 
by their addition is partly offset by the introduced confusion.


I am not sure is removing @staticmethod would have been sufficient in 2.x.


 def cmd():
 print("Test")



top=tkinter.Tk()
cb=Checkbutton(command=cmd)
cb.pack()

Button commands have to be tcl functions.  Tkinter wraps Python 
functions as tcl function.  Static methods also wrap python functions, 
as a .__func__ attribute.  So the code if one passes cmd.__func__.



Maybe there is a bug in tkinter, that it doesn't work with static methods?


One could propose that tkinter test whether callables are staticmethods 
and unwrap them when they are.


Classmethods also do not work as is.  By experiment, the following works.
cb=Checkbutton(command=lambda: C.cmd.__func__(C))
But if the class were nested, it would be more complicated.

tkinter abbreviates tk interface.  In particular, it adds a Python

This extra "-" confuses people when showing up in the Traceback info. Can't 
figure out why the author want to do this.

To clarify what Peter said, tkinter is a GUI library written in the Tcl 
programming language.


The 'tkinter' module in Python's standard library is just a wrapper 
around that library.


The Perl and Ruby programming languages also have wrappers.
The "-" is added because the Tcl language requires it.

Thank you for your answer. I try not to use the ttk by comment the line "from 
tkinter.ttk import *", and also try your "Style" modification codes, both 
work:-)

This extra "-" confuses people when showing up in the Traceback info. Can't 
figure out why the author want to do this.

I can confirm the problem. It looks like the bug was introduced when the 
example was converted from stock tkinter to the new ttk widget set.

While

frame["background"] = color

works when frame is a tkinter.Frame widget the newer tkinter.ttk.Frame 
widget uses "styles" to configure its appearance. 

I have not used that new feature, but with the help of

http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/ttk-style-layer.html

and some trial and error I modified the example to use a style:

Ask for help about a tkinter problem

[jfong]

I am running a tkinter tutor downloaded from web,

#file button.py

from tkinter import *

...

I run it under the DOS box:

When I looked into the file tkinter\__init__.py, I found there is codes which

Is it the reason this exception raised? Why is that?

Which means that you were creating a GUI window with Python as root,
which is to be avoided if you can. If you can't avoid it and you're
running it with sudo in a bash console, rather than a root console, then
I'd suggest adding the line...

XAUTHORITY=$HOME/.Xauthority

...to the root's .bashrc which avoids putting a specific user's
xauthority file in the root directory.

Worked for me on an installed Debian, inside Xfce with xfce4-terminal.

1) What version of Python are you running?
2) Are you running inside some kind of graphical environment?
3) Do you have any sort of permissions/environment change happening? I
get an error like that if I try sudo python without any sort of
guard.

Are you using ssh to connect to the system? If I create a file and run it
directly from the machine I am physically sitting at, it works fine and the
window is displayed as expected:

[steve@ando ~]$ cat test.py
import Tkinter
root = Tkinter.Tk()
root.title(Fenster 1)
root.geometry(100x100)
root.mainloop()
[steve@ando ~]$ python2.7 test.py
[steve@ando ~]$


But if I ssh to the machine, I get an error (although a different error from
you):

steve@orac:~$ ssh ando
steve@ando's password:
Last login: Thu Dec 12 19:27:04 2013 from 203.7.155.68

self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable


If I set the $DISPLAY environment variable, it works for me:

[steve@ando ~]$ export DISPLAY=:0
[steve@ando ~]$ python2.7 test.py
[steve@ando ~]$ logout
Connection to ando closed.

But ando is the machine I am physically seated at, so it's not surprising
that I can see the window on the X display. If I go the other way, and try
to run the code on orac (the remote machine), I get the same error as you:

steve@orac:~$ export DISPLAY=:0
steve@orac:~$ python2.6 test.py

So you need to X-forward from the remote machine to the machine you are
physically on, or perhaps it's the other way (X is really weird). I have no
idea how to do that, but would love to know.

With SSH, that's usually just ssh -X target, and it'll mostly work.
But there are potential issues with .Xauthority, which is why the sudo

On a LAN, it's not even slow! I've actually run VLC through ssh -X and
watched a DVD that was in a different computer's drive. That was fun.

You can even get a Windows X server and run Linux GUI programs on a
Windows client. *Very* useful if you're working with both types of

I usually use ssh -Y.  The -Y argument toggles trusted forwarding.  From
the ssh man-page:

 -Y  Enables trusted X11 forwarding.  Trusted X11 forwardings are
not subjected to the X11
 SECURITY extension controls.

I've found -Y is a bit faster than -X in my experience (I've never really
had many problems with X-forwarding on LANs in my experience -- even with
OpenGL windows)

self.tv.selection_set(top)

TestMixin().mainloop()

There are some things i dont understand:
1) resizing of the field widths does work in principle, but the
resulting field is exactly one charakter to small.
2) I think, resizing should be clearer, but i have no idea, how.
3) The horizontal scrollbar does not work as expected. It does not react
on resizing the application window but only on resizing the headers of
the fields.

Maybe someone can give me some hints.

Python 2.7, tkinter problem on OSX

[Julien Pauty]

Dear list,

Last version of my software relies on ttk. Under windows and linux
this is fine. But, OSX users are facing problems (I don't have access
to a Mac myself for testing...). Those with OSX 10.6 can run the
program. It seems that OSX 8.6 ships with Tk8.5.

People with OSX 8.5 cannot run the app. I told them to install python
2.7 which seems to be the first version on OSX to ship with Tk8.5.
However, the program still does not run. I asked a person to launch a
python 2.7 interpreter and try to import tkinter. This is an excerpt
of the output:

  from Tkinter import *
  File 
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py,
line 39, in module
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: 
dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_tkinter.so,
2): no suitable image found.  Did find:
        
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_tkinter.so:
no matching architecture in universal wrapper

Full log is there: http://pastebin.com/vky8FbrP

I asked a person to simply open a python2.7 shell and import Tkinter.
He got the same error.

All of this is executed with Python 2.7rc1. Archives that are on the
ftp of python.org.

I have seen this bug http://bugs.python.org/issue9045, which is
related, but deals with the specificities if OSX 64bit.

Can this problem be solved by installing Active TK 8.5 for OSX ?

Anybody knows what is the good combination of installer / libraries to
install to run a ttk application on OSX 8.5 ? Ideally, I would like to
document the setup procedure for 8.5 users.

Cheers,

Julien

The OS X equation is confuzzulating due to version and API changes in
Mac OS X.  Let's review ...

OS X 10.5 ships Tcl/Tk 8.4 built 32-bit only i386+ppc using Carbon.
OS X 10.6 ships Tcl/Tk 8.5 built 32/64 i386+x86_64 using Cocoa.

The Cocoa port of Tk was necessary for 64-bit support, as Apple never
did supply the promised 64-bit Carbon.  Tk 8.5 has Cocoa as an option,
and it is default in Tk 8.6.

ActiveTcl 8.5 still ships as 32-bit i386+ppc Carbon because going to
Cocoa also means you have to drop OS X 10.4 support (out of curiousity
- does anyone care about OS X 10.4 anymore that isn't stuck on what's
already installed?).  8.5 plans to do so later this year (leaving
behind our OS X 10.4 brethren to older versions).  ActiveTcl 8.6 (Tcl/
Tk 8.6 is in beta) already ships i386+x86_64 Cocoa.

Now there is the issue that Tkinter links to a specific version of Tcl/
Tk.  I am currently working on a patch that will remove this
limitation (making the binary Tk version independent).

So what do you do?

Well, it depends on what mix you are trying to make.  The easiest is
to just run
arch -i386 python2.7
and then it will find the compatible i386 Tk.  The next release of
ActivePython 2.7 (which is building i386+x86_64) will have the Tk
version independence, so it could work with core Tk or AT 8.6, or 8.5
in 32-bit mode.

Less confuzzulated?

 Im using Mandriva 2008.1.  I have to tell you honestly that I'm not 
 sure
 exactly how I installed Python.  Originally I had installed 2.5 from 
 RPM
 but 2.6 was not available for my distro (2008.1) in RPM.  I downloaded
 something from python.org and installed.  Not sure if it was tarball or
 zip file.
 Zip or tar doesn't matter, you are installing from source.

 Python has to find the necessary include files for tcl/tk. These are in
 separate packages that you have to install before you invoke Python's
 configure script.

 I don't know what they are called on your system -- look for tk-dev.rpm,
 tcl-dev.rpm or similar.

 You may run into the same problem with other modules like readline.

 Peter


 Thank you Peter.  I understand what you are saying but don't know how to 
 do
 it.  Although I installed from source, I followed a cookbook recipe.
 Could you tell me what files to execute, where they might be, and file
 arguments?  I'm just ignorant, not stupid. ;-).

 Paul



 Just install the tkinter package from the Mandriva Linux Control
 Center's Software Management system.  I just did it, doing a search for
 tkinter brought it right up.  All done.

 --David

Thanks to all for your patient help.  I have made some progress, but still 
no success.  I installed Active Tcl-8.5.7 and corrected the PATH 
accordingly.  However I still get a missing message on building Python. 
Failed to find the necessary bits (!) to build these modules:


_tkinter (among others)
To find the necessary bits, look in setup.py in detect_modules() for teh 
module's name.

Not sure what bits are, euphemism?  but am about to wipe the disk and 
reinstall linux, etc.

Once you have the necessary development packages for tcl/tk just go into the 
directory where you unzipped the source and

./configure
make
sudo make altinstall

Unfortunately I don't know the names of these packages nor how to install 
them, and Google didn't turn up anything useful.

If you don't get any additional answers here you may try a Mandriva forum 
since this is not a question that requires python knowlegde.

secret.

How about telling us what the actual error is, and the actual line that 
causes the error? Chances are very good that the error message will tell 
you everything you need to know about why the program fails.




 There are a number of Frames containing Radiobuttons in the program. The
 individual lists are long enough no one in their right mind wants to
 hand code such repetition and then try to maintain it. 

Then perhaps you should think about changing the user interface to make 
it simpler to manage, and simpler to use. Not every task requires a 
hammer.

I don't know tkinter, but I can see a problem with your code.  You're 
using the [] operators on c, but you never initialize c.  Of course, you 
have a tiny fragment of code, and we're supposed to guess the rest.  But 
normally, when you build a list, you start with:

mylist = []
for     in :
   c =  new widget
   mylist.append(c)

Now, c is just temporary, but mylist contains reference to all the 
widgets.  So later on, you can use  mylist[42] to get button# 42.


A separate problem is that mylist should be a member of a class derived 
from the frame widget, or something like that.  So if this code is part 
of an __init__ method of a class, there are a few self items needed.

Suggestions wanted on Tkinter problem

[norseman]

One suggested I change the subject line - OK
I also replaced the [TAB]s since I noticed the Emailer seems
to get very confused with them.



Problem:
Using Python 2.5.2 and Tkinter ??? (came with system)
List made and for loop in use
lst=[ (S, Single), .]

for mode, text 
c = Radiobuton(.
c.pack()

At this point the program runs, but I cannot control gray-out of a
specific Radiobutton.

If I:

counter=0
for mode, text 
c[counter] = Radiobuton(specified_frame,..
c[counter].pack()
counter += 1
.
.
blockUseOf= $varSetElsewhere
c[blockUseOf].config(state = strSetElsewhere)

Program crashes on Radiobutton line.

There are a number of Frames containing Radiobuttons in the program.
The individual lists are long enough no one in their right mind wants to
hand code such repetition and then try to maintain it. Not even with a
code generator. (Number and organization will change over time.)
How do I set things to be able to control any given Radiobutton from
elsewhere in the program and still use the for-loop loader?

I can't test your code because I don't have the test image and for some 
reason it does not recognize a tiff of my own. But, just glancing at 
your code, it looks like a quick-fix would be to set self.zoom to a 
sentinel at the end of refresh() and return 'break' at the top of the 
methods that use self.zoom if it is said sentinel value (e.g. if 
self.zoom == WHATEVER_SENTINEL: return 'break'). You may also want to 
return 'break' for event responders that should terminate the event 
chain. This is a general technique to stop a lot of unwanted event

Thanks!  I hadn't known about the return 'break' technique.  But
I don't follow your sentinel suggestion; how would that sentinel
ever get reset?  It seems as if the first time through the event
chain it'd be set to the sentinel, and the routines that pay
attention to it would never execute.  What am I missing?
I tried simply returning 'break' at the end of refresh() and
that made no change in behavior.

(Note that zoom should be constant at 1.0 for the life of
this program; I put it in because I'm planning to put in expansion/
contraction of images after I get resize  scrolling working
together.  Eliminating all multiplications by self.zoom confirms
this belief; no change in behavior).

One thing I've been looking for (including in the source :-J) is
a description of the precise process that the geometry manager
goes through in figuring out and then setting sizes for the
various widgets (on resize or, apparently, startup).  I suspect
with that + the return 'break' technique I could get this to
work.  But I haven't been having any luck finding that documentation.

If you'd like me to send you the test.tiff image, I'm happy to, but
it's nothing special; just a screen capture of a random google maps
satellite view that I use for testing.

Presumably you would set it from some kind of input. Basically, if you 
don't need to zoom, you wouldn't bother scaling the image. It is the 
scaling step that is expanding your image.


You might want to set any borders to 0.

It seems as if the first time through the event

chain it'd be set to the sentinel, and the routines that pay

You will want to return 'break' at the end of callbacks, like 
display_tag_and_size()

I've never found that either. I usually tweak things by trial and error. 
Tkinter (Tk) has some bad habits. Most of the time it is very hard to 
get the precise dimensions of widgets by asking them. The problem is 
exacerbated by platform specific modifications like TkAqua. Ive found 
the best approach is to tweak the math so that the sizing comes out 
consistent and then test and patch for every platform you support. 
Sometimes, if you experiment enough, you can figure out by inference 
what Tk is actually doing under the hood.


The other, more sane option, is to attempt to make guis that don't rely 
on precise size information. Its less satisfying than the pixel level 
control one hopes for, but makes for a faster development process.


Also, you might want to look into Pmw. It has scrolled canvas and 
scrolled frame widgets that might be helpful to you. There is no need to 
reinvent the wheel except for your own enlightenment.

TkInter: Problem with propagation of resize events through geometry manager hierarchy?

[Randy Smith]

Hi!  I'm looking for help with a Tkinter program's handling of resize.
I'm trying to do a fairly simple widget that shows a cropped part of a
larger image, and let's you navigate within the larger image through a
variety of methods.  The widget hierarchy is:

root
  ImageWidget (my class)
Label (contains the image)
Horizontal Scroll Bar
Vertical scroll bar

The cropping and scrolling works fine.  But when I try to add
responding to resize events, I get into trouble.  Specifically:
* When I naively change the size of the image shown to be borderwidth
  less than the size indicated in the configure event, the size of the
  image shown grows gradually but inexorably when I start the test
  app.  (Sorta scary, actually :-})
* When I fiddle a bit to figure out what the actual difference in size
  is between the Configure event and the image that can be displayed,
  I get a vibrating, jagged display of the image.

Investigation suggests that multiple configure events are hitting the
label in response to each user resize with different sizes.  I'm
guessing that when I resize the image in response to those different
events, that creates new resize events propagating through the window
manager hierarchy, which creates new configure events, which means my
handler changes the image size, which ... you get the idea.  However,
everything seems to work fine if I leave out the scroll bars and just
have a label in a frame inside the root window; the image resizes
fine.  If the scroll bars are in place but I don't have the image
resize bound to the configure event, I get two sets of resize events
propagaing through the system on startup; without, I just get one.

Event lists and code included below.  Any help would be appreciated.
Thanks!

Wow, nice!
But, with join i can't padding with 0.
'-'.join(str(random.randint(0, 60)) for dummy in xrange(6))

Then, i has been used:
a[i] = %02d % int(random.randint(0,60))
 I will change int(random.randint(0,60)) for random.randint(0,60), only.
Thank you, guys !! ;-)

The problem was solved when removed the second mainloop.

I will use the Toplevel instead Tk() again. Thank you for the nice lesson !!

 Not the problem but unnecessary complex.  `random.randint()` already

 implies a call to `str()` while formatting.  If you put something into a

 Also for style, you might want to group the import lines so they look
 like this:

 from Tkinter import *
 import sys, random

 A bit more pythonic. :P

In that case you probably want to take out the 'from' import and:

import Tkinter, sys, random

in order to avoid any namespace issues especially if you have a large
project with lots of gui manipulations.  But that's just me being
pedantic. ;)

Thread Tkinter problem

[Davy]

Hi all,

I am using thread and tkinter to write some simple programs and
solidify my understanding of Python thread/GUI programing. The scheme
is thread + queue + GUI. One child thread (gen_board_thread) generate
board and insert data into queue infinitely. Meanwhile, the main
thread canvas widget get the board data from queue.

I assume the program will run forever if don't close them explicitly,
but the fact is contrary to my understanding. It seems the child
thread insert data till queue is full, then the main thread eat the
data till the queue is empty, and the main thread starve(when timeout
option is set) and die. So the two thread work like two function call,
but not two thread!

Is this situation caused by deadlock(I guess main thread has higher
priority)? Or how can I know whether the child thread is still alive?
Ultimately, how to solve the problem?

The code are attached.
Any suggestion will be appreciated :-)
Best regards,
Davy

You don't need the brackets: while True: is good enough

time.sleep(0.3)

write: if not data_queue.full():  , and lose the brackets here too.

if (gen_flip == 1):

Re: Windows / Tkinter - problem with grid - not able to place widgets at desired places

Hi,

I'm learning Python and Tkinter. I've started programming in Eclipse

My desired GUI is attached in the mail. Although I've tried writing a

the GUI. The Biggest problem seems to be with the Grid Manager in terms
how it divides a window in Rows / columns. etc. I'm not able to place
none of the widgets correctly in the GUI.

For your convenience, I'm attaching this code also as myModule1.py .
Please some one review it and help create me this GUI.


Uhm, I don't think you should use the grid manager to obtain a window 
like that. The grid manager is for equally distributing widgets both 
horizontally and vertically. 
And I'm not sure that you can realize that window look with Tkinter.
You could get close by horizontally packing each widget row in a frame 
and then vertically packing the frames in the window. But the look will be
quite different than your target. If you are not satisfied with that I
suggest you move to other toolkits which have more complex geometry 
managers than .pack and .grid.

 Where's `tagOrId` coming from?  That's a `NameError` here.

Also, the arguments of Canvas.move() are positional.

self.canv.move(rect, 0, 10)

should work though the direction of the move might surprise you.

Re: Tkinter Problem?

[Davy]

Hi all,

I have solved the problem after read some code. Because Tk.Canvas do
not have a focus, it does not receive a key input. The solution is
bind key input to the highest level 'root'

root.bind('Up',self._onUpKey)

I'm not sure, but I don't think you can bind the a key to a
canvas...you'd want to bind to the rectangle itself somehow.

Some articles on binding:

http://effbot.org/pyfaq/i-can-t-get-key-bindings-to-work-in-tkinter-why.htm
http://www.pythonware.com/library/tkinter/introduction/events-and-bindings.htm
http://docs.huihoo.com/tkinter/an-introduction-to-tkinter-1997/intro06.htm

Info on the Canvas object:

# this one talks about setting the focus on an item within the canvas
so that it has key bindings...maybe that will work.
http://effbot.org/tkinterbook/canvas.htm
http://www.pythonware.com/library/tkinter/introduction/canvas.htm

I am not a Tkinter expert. I am much better with wxPython, but I am
only starting to be able to answer questions on that topic.

Hopefully someone with more knowledge will show up shortly.

without the 'bundle_files' option, but when I add that option in
(bundle_files: 1), the built executable gives me the following error:

Fatal Python error: Interpreter not initialized (version mismatch?)

This application has requested the Runtime to terminate it in an

This happens when the compiled Python executes the line from Tkinter

Simple Tkinter problem

[gmarkowsky]

Hi all,

I'm trying to write a GUI that will put up multiple widgets in
succession. My problem is that each widget also contains the previous
widgets when they pop up. How do I reinitialize the widget each time so
that it doesn't contain earlier ones? Actually, another question I have
is, is there a way to set python so that it will assume any undefined
variable is 0 or ''? That is, I have several statements like If k  0
then so and so and I would like it to assume k=0 unless I tell it
otherwise. I've just been defining k=0 at the start of the program but
it seems there should be a better way.

Re: Simple Tkinter problem

Here's my Tkinter class:

class TwoChoice:
def __init__(self, master):

frame = Frame(master)
frame.pack()
m = Label(root, text= maentry)
m.pack()
n = Label(root, text= fave)
n.pack()

self.button = Button(frame, text=home_team, command=
self.comm_1)
self.button.pack(side=LEFT)

self.hi_there = Button(frame, text=vis_team,
command=self.comm_2)
self.hi_there.pack(side=LEFT)

def comm_1(self):
print home_team
root.quit()

def comm_2(self):
print vis_team
root.quit()

I call it by

root = Tk()
gui= TwoChoice(root)
root.mainloop()

The next time I call it I want to just run the same thing but with
different values for the variables. Instead it gives me like two copies
of the widget.

Re: Simple Tkinter problem

Greg,

Run the following code to see how pack_forget() or 
grid_forget() works, it makes previous widgets 
disappear but not go away.  If you call grid() or 
pack() again after using grid_forget() the widget 
returns. 


root = Tk()
class Ktest:
def __init__(self):
self.Ftest1()

def  Ftest1(self):

try:
self.test2.grid_forget()
except AttributeError :
pass
self.test1 = Button(root, text='Push #1
   button', bg = 'yellow', width = 25,
command = self.Ftest2,
 height = 25)
self.test1.grid(row=0, column=0)


def Ftest2(self):
   self.test1.grid_forget()
   self.test2 = Button(root, text='Push #2 
   button', bg = 'green',
 width = 15,
command = self.Ftest1,
 height = 10)
   self.test2.grid(row=0, column=0)

if __name__==  '__main__' :
Ktest()
mainloop()

a variable.

I am pretty sure it's the underlying Tcl/Tk that's causing you grief.

Does your application itself use Tcl/Tk anywhere? I'm guessing not, as 
I'd expect you'd already have gone to some trouble to get the menus 
right.

Unfortunately, I can't offer a solution. You may want to post to the 
Tkinter mailing list (via news you can use gmane, group 
gmane.comp.python.tkinter; I'm not sure if you have to sign up for the 
list before posting).

You could import Tcl/Tk yourself up front and then fix your 
application's menus once. But Aqua Tcl/Tk is painfully slow to start up, 
so this could really slow down startup of your own application. (Note 
that you'd have to be prepared for Tkinter to be missing (it certainly 
is by default on 10.3). You might also have to make users use one 
mainloop (see next paragraph) for this to work.

James Stroud also brings up an interesting point--that it could be 
dangerous if there are multiple scripts each trying to run their own 
mainloop. But if only one runs at a time, and cleans up after itself, 
you're probably OK. If that's not the case, you may want to start a Tk 
main loop yourself and ask users to use that loop. Again, though--it'll 
take time, and it'll only help those users who use Tkinter in their 
scripts.

This menu mashing is a problem. This really has nothing to do with 
programing in Tcl, Tk, Python, or Tkinter. First of all, the About Tcl 
 Tk is hard-wired during the build of Aqua Tk. To fix this will 
require downloading the sources and building your own Aqua Tk from 
scratch: http://tcltkaqua.sourceforge.net/8.4.10/

Alternatively, you can res-edit the appropriate files. The About Tcl  
Tk menu item is held in an rsrc file. I forget exactly where, but I can 
take a look on my ibook if you are interested in this route. To do this, 
you will want a working copy of resknife. I had some trouble with it, so 
I had to build it for my ibook with xcode--IIRC, the build I downloaded 
had problems saving. Getting the source and building on my computer 
fixed it. Its a great program.

I'm guessing the best way to get around destroying your menus is to 
intercept calls to Tk(). I've had bad luck with multiple Tk() instances 
running in the same session (this is the case with EVERY implementation 
of Tkinter I've seen, Linux, Mac, etc.). StringVar and IntVar instances 
get very screwy with multiple Tk()s. You might want to re-define Tk() to 
return the root instance created by your program. Also, knew Toplevel()s 
will have their own menus, resulting in your application's menus 
becoming replaced while the Toplevel() is in the foreground, that's just 
how Aqua Tk works. This may be something you have to live with if you 
want your students (I'm guessing) to learn about python in your environment.

TKinter problem

[C D Wood]

To whom this may concern,
Below is the source code, which

demonstrates a
problem I am having making a GUI for my python project  work.
'table.txt'
is a file that is read from the same folder.

My code writes to a text file 'table.txt', and 'table.txt' is displayed
in
the GUI. The user can generate new data at the click of a button
which re-writes 'table.txt', but I can only add the new table to the
GUI
 window rather than 'update' the existing one.

Any assistance would be much appreciated,

Regards,
Christian Wood.

 To whom this may concern,
 Below is the source code, which

 problem I am having making a GUI for my python project  work.
 'table.txt'
 is a file that is read from the same folder.

 My code writes to a text file 'table.txt', and 'table.txt' is displayed
 in
 the GUI. The user can generate new data at the click of a button
 which re-writes 'table.txt', but I can only add the new table to the
 GUI
  window rather than 'update' the existing one.

 Any assistance would be much appreciated,

What you want probably looks like this:

from Tkinter import *
class MoC:
def __init__(self, master):
frame = Frame(master, width=600, height=800, bd=1)
frame.pack()
iframe4 = Frame(frame, bd=2, relief=SUNKEN)
Button(iframe4, text='Display table.txt',
command=self.DisplayUpdate).pack(side=LEFT, padx=5)
Button(iframe4, text='Quit',
command=self._quit).pack(side=LEFT, padx=5)
iframe4.pack(expand=1, fill=X, pady=10, padx=5)
iframe5 = Frame(frame, bd=2, relief=SUNKEN)
self.text=Text(iframe5, height=10, width =70)
# read the file in the update function; create Text  Scrollbar
only once
self.text.pack(side=LEFT, fill=X, padx=5)
sb = Scrollbar(iframe5, orient=VERTICAL,
command=self.text.yview)
sb.pack(side=RIGHT, fill=Y)
self.text.configure(yscrollcommand=sb.set)
iframe5.pack(expand=1, fill=X, pady=10, padx=5)
self.DisplayUpdate()
def _quit(self):  # quit is a keyword in python 2.4 IDE
root.destroy()
def DisplayUpdate(self):
fd = open('table.txt')
lines = fd.read()
fd.close()
self.text.config(state=NORMAL)
self.text.delete(1.0, END)
self.text.insert(END, lines)
self.text.config(state=DISABLED)
# previous 4 lines are to make the text READONLY, see more in:

Tkinter problem

[dale cooper]

Hi everybody!
I've recently installed python2.4.2 on Fedora 4 (from downloaded
sources), but it appeared, that I can't use Tkinter module:

 import Tkinter
Traceback (most recent call last):
  File stdin, line 1, in ?
  File /usr/local/lib/python2.4/lib-tk/Tkinter.py, line 38, in ?
import _tkinter # If this fails your Python may not be configured
for Tk
ImportError: libBLT24.so: cannot open shared object file: No such file
or directory

I tried the solution given in README file for RH9 (./configure
--enable-unicode=ucs4) despite they wrote the newer wersion didn't need
this hack. This is what I had after make instruction:

INFO: Can't locate Tcl/Tk libs and/or headers
*** WARNING: renaming array since importing it failed:

*** WARNING: renaming _multibytecodec since importing it failed:
build/lib.linux-i686-2.4/_multibytecodec.so: undefined symbol:

running build_scripts

It seems that --enable-unicode=ucs4 wasn't the right way. I tried
another hack: ./configure --enable-shared, but it still couldn't locate
Tcl/Tk libs and/or headers. Then I installed RPMs:

[EMAIL PROTECTED] Python-2.4.2]# rpm -q tk
tk-8.4.9-3
[EMAIL PROTECTED] Python-2.4.2]# rpm -q tcl
tcl-8.4.9-3
[EMAIL PROTECTED] Python-2.4.2]# rpm -q tkinter
tkinter-2.4.1-2

and tried to do the hacks above, but it still could'nt find these libs.
What can I do?

this seems to indicate that the build process picked up the Tk BLT extension 
[1],
but that you haven't installed that extension properly.

Re: Tkinter problem

[dale cooper]

Thanks, but I've got another question:

can't find Tcl configuration script tclConfig.sh

This is what I received trying to install TkBLT. What is tclConfig.sh?
I did installed tcl/tk 8.4.9-3 as I mentioned before, I tried to find
this file, but I don't have it in my filesystem. How to get it?

This file comes from the following package:
$ rpm -qf /usr/lib*/tclConfig.sh 
tcl-devel-8.4.9-3

Fedora generally splits packages which are libraries into foo and foo-devel
(and maybe others).

Re: [Tkinter] problem

[Jeff Epler]

These lines
 if __name__ == '__main__':
 OptionsWindow()
mean if this source code is the main program (not an imported module),
call OptionsWindow().  So the behavior should be different when the
source code is the main program ('python opt_newlogin.py') and when it's
imported ('python -c import opt_newlogin')
