I'm testing a small Tkinter app on Cygwin, and have noted a problem
behaviour with tkMessageBox showinfo method (I presume the problem
would also occur with showwarning or showerror).  Msg text in the
showinfo dialog is not visible, nor is the text in the OK button.

If I put the same message text into a label and display that label in
a Toplevel widget, the text is visible.

I note that tkMessageBox code (created by Fredrik Lundh way back in
1997!) inherits from Dialog, and passes options to it.  I wonder if,
in cygwin, I need to explicity set a font family or type, or a text
colour, and if so, how to do that?  I tried adding a font parameter to
the showinfo method call, but it only accepts default, icon, message,
parent, title or type.

thanks,

Subject: [Tkinter-discuss] subprocess problem in cygwin with Tkinter
Message-ID: <d4c0d4800601041802x147d755as28bda185ea3b1302@mail.gmail.com>

this has me puzzled; I've created a small test app to show the problem
I'm having.

I want to use subprocess to execute system commands from inside a
Tkinter app running under Cygwin.

When I open a python interpreter and run my subprocess command, all is
well. But when I run the same command from inside a Tkinter app, I'm
getting errors.

I'm using this version of Cygwin:
$ uname -a
CYGWIN_NT-5.1 Mulata 1.5.18(0.132/4/2) 2005-07-02 20:30 i686 unknown unknown Cyg
win

When I run my command in a python shell, all is well:

smidwint at Mulata /cygdrive/c/programs/pipeworksb/lib/python/popt
$ python
Python 2.4.1 (#1, May 27 2005, 18:02:40)

>>> for dir in dirlist:
...     print dir
...
__init__.pyc
browser.bat
test_subprocess.py
test_subprocess.py.bak
>>>


When I run the same command in a Tkinter app, I get an exception:

smidwint at Mulata /cygdrive/c/programs/pipeworksb/lib/python/popt

  File "/usr/lib/python2.4/subprocess.py", line 918, in _execute_child
    self.pid = os.fork()

Here's a sample Tkinter app that reproduces the problem:

#test_subprocess.py
import subprocess, os
import Tkinter

def dir_list():
    '''provide a listing of files in a directory'''
    #need to know which system to draw from
    curdir = os.getcwd()
    dirlist = subprocess.Popen('/usr/bin/ls', shell=True,
bufsize=2048, stdout=subprocess.PIPE).stdout
    #dirlist = subprocess.Popen(['ls',' -l'],
stdout=subprocess.PIPE).stdout.communicate()[0]
    print dirlist
    msgList = []
    for dir in dirlist:
        print dir
        msgList.append(dir)
    msg = '\n'.join(msgList)
    return msg

root = Tkinter.Tk()
l = Tkinter.Label(text=dir_list())
l.pack()
b = Tkinter.Button(text='ok',command=root.destroy)
b.pack()
root.mainloop()


BTW, the test_subprocess.py test script that ships with Cygwin python runs fine.

any ideas?

Subject: [Tkinter-discuss] Pmw problem in cygwin with Tkinter
Message-ID: <d4c0d4800601051226n6d35e442mced24204f009a73@mail.gmail.com>

I have a Tkinter app running on cygwin.  It includes a Test menu item
that does nothing more than fetch a directory listing and display it
in a Toplevel window (I'd use a tkMessageBox showinfo widget, but for
some reason the text is invisible on cygwin).

After I close the Toplevel widget, all of the menus in my app behave
as though they have no contents to them, i..e I can press on the File
menu button, and see it depress, but the Exit submenu does not appear
(and neither do any of the other menus' submenus).  However, a Quit
button in my status bar does respond, so the problem lies with the
menu.

Below are two apps that illustrate the problem. It's obvious that the
problem is with Pmw, and in particular with the menubar widget.  The
first test app uses Pmw, and displays the problem behaviour.   The
second test app uses basic Tk menus, and does not have a problem.

Any clues?

Mohammed, thanks for putting that outline together.   It will be quite
useful when completed.

My suggestion would be to put the comparisons at the top of the page,
including your views on the pros and cons of each widget set.  The
actual list of what each widget set includes could come later. Or
better yet, delegate each list of widgets to its own page - that would
be more readable.  (OOPS - just read your stuff at the page bottom,
where you make the same suggestions).

I noted that the Notebook page appears in several places, but the
example is from only one widget set. The EntryField link appears under
Pmw but the example is from Tkinter.

A couple of other notes I would make: you can add a pros and cons for
basic Tkinter, since it is the default choice.

e.g. pros
- comes with all python installations and is available on all platforms
- smallest footprint of any widget set
- extensive documentation is available

cons
- some people think it's ugly

Another thing about Pmw. Currently I'm working on a Tkinter app
running on python in the cygwin environment.  I've found some
weirdness (invisible text on tkMessageBox widgets like showinfo),
non-functioning MenuBar widgets after doing a subprocess fork, etc.
I'm having (for now) to revert to basic Tkinter widgets.

Other cons to Tix, bwidget:
- can be problematic to install on some platforms; some users have
problems getting python to find the widget set (raw tk commands may be
needed).

cheers,

Sorry, I don't have much ideas here; however on my linux box your test app
runs fine, and if tkMessageBox does not work either it does not seem so
obvious to me that Pmw causes the problems.

Hi Michael -

you tested my apps on a linux box and not on cygwin?   The apps run
fine on linux, it's cygwin that is the problem.

that's what I thought, it's just because you wrote that you think it's Pmw that causes the
problems. Unfortunately I don't have a windows box here for testing.
Have you tried to narrow down the problem, for example do the Pmw demos work?

I think on windows Tk uses for both the MessageBox and the menus native windows controls,
so I think the problem might be running Tk from cygwin.

FSR, Pmw itself works fine on my installation. But FSR, I cannot run 
your sample unmodified because cygwin cannot fork - had to put things 
into dirlist manually for a test.

$ python /test_subprocess2.py
C:\cygwin\bin\python2.4.exe (2524): *** unable to remap 
C:\cygwin\bin\tk84.dll to same address as parent(0x18700000) != 0x18C10000
     23 [main] python 596 fork_parent: child 2524 died waiting for dll 
loading
Execution failed: (0, 'Error')

Bottom line: I think cygwin is too much of a moving target. An example: 
FSR in my old install "ssh-add " always hanged on the first invocation. 
After pressing control-c and rerunning ssh-add everything works (FSR!).

System: - Windows 2003 Server Std Edition
        - Python 2.4.1 (#1, May 27 2005, 18:02:40)
          [GCC 3.3.3 (cygwin special)] on cygwin
        - Pmw 1.2
        - Cygwin Base 1.3.20a-2

Btw, cygwin + tkinter / pmw seems to create the exact same native 
widgets on my system and do not use X  (XWin.exe).

well you may be right.  We've got other issues with it as well, not
involving python. But we have to use it since we have to deploy a unix
app on a windows box, and we don't have time or resources to port the
app to windows at this time.

for now I'll try to steer clear of Pmw and just use native Tkinter
widgets.  No problem with any of them so far.

i dont know why will you rewrite the Pmw part and not changing the console commands themselves. i rewrote the commands in the code snippet you sent before to use windows commands and it worked

Perhaps I wasn't very clear on the nature of the problem.  As Mohammed
states,  my example apps work fine under Windows.  But those little
apps aren't part of the unix app. I'm trying to create a Tkinter
administrative app for that unix app, and communicate with it via
subprocess, then display information in Tkinter widgets, rather than
force the user to use vi as his interface!   The problem that I'm
finding is that the Pmw widgets don't behave properly when run in
cygwin.  I want my Tkinter admin app to run in cygwin, like the unix
app, to simplify communication with the unix app.

since by definition I have windows available on the workstation in
addition to cygwin, perhaps my approach should be to write my admin
app using the Windows version of Tkinter. That way Pmw will function
properly.  However, I'll have to then start cygwin via subprocess and
send additional chained commands to cygwin to get the unix app to run.
I'll think about that approach for a while..

hmmm, i would use another approach. I would reimplement all the underlying commands and leave the other parts untouched. you may find some commands similar (like cd) and you will implement only the non-existing commands (like ls) which, i think, won't be too many

you mean, implement the Tkinter app in windows, and use windows
commands wherever possible, only invoking cygwin where absolutely
necessary?

Message-ID: <13a83ca10601100312u5d7469dah@mail.gmail.com>

Hello,

I'm doing a small program to capture screenshots.

But obviously I don't wan my GUI to be visible during the sreenshots and I
want to continue to take sreenshots (with my key binding) even when the
program doesn't have the main focus anymore.

I'm running Python 2.4 on Win XP Family.

Do you have an idea how I could do this ?

Thanks in advance

Hi there

ui updates with tkinter will only happen IMHO after your method returns. 
use the widget.after() method (check 
http://infohost.nmt.edu/tcc/help/pubs/tkinter/universal.html). Something 
like this:

def screenshot(event):
    fen1.iconify()
    fen1.after(200,doscreen)

i=0
def doscreen():
    global i
    print " screen !"
    i= i+1
    name = "session1picture"
    name= name + str(i)
    print name
    myscreen= ImageGrab.grab()
    myscreen.show()
    myscreen.save("C:/"+name+ '.jpeg')
    fen1.deiconify()

If you want ro remove the taskbar entry you can apply the win32 style 
MYWS_EX_NOACTIVATE (at least with win2000 or later). This requires C 
programming, and is just the first thing that came into my mind.

cheers

not exactly. I meant:
1. leave the *Pmw* version untouched
2. leave the original application untouched
3. don't use cygwin. instead, implement the missing commands yourself; possibly by writing wrappers around windows commands
I hope I'd clarified it

Thanks very much Gill for the UI update help.

I've also found something very interesting to control the app when it's not
in focus anymore with pyHook:

The pyHook library wraps the low-level mouse and keyboard hooks in the
Windows Hooking API for use in Python applications. This short tutorial
demonstrates how to set keyboard and mouse hooks, what information is
available about events, and how to pass or block events.

Python rocks :)

mohammad, can you please use a quoting approach that makes it
explicit what message you're replying to (including who wrote it),
and works also if people read your messages as plain text.

as it is now, most of the messages from you looks like this example

    and we don't have time or resources to port the
    app to windows at this time.
        try to steer clear of Pmw and just use native Tkinter
    widgets.  No problem with any of them so far.

    i dont know why will you rewrite the Pmw part and
    not changing the console commands themselves. i
    rewrote the commands in the code snippet you sent
    before to use windows commands and it worked

which would be a bit more readable as, say

    i dont know why will you rewrite the Pmw part and
    not changing the console commands themselves. i
    rewrote the commands in the code snippet you sent
    before to use windows commands and it worked

at least in the context of this mailing list (your poetry teacher may
prefer the former, though).

Subject: [Tkinter-discuss] Drawing waveform on a Canvas
Message-ID: <20060118140734.7b9513c0.klappnase@web.de>

Hello list,

I am trying to draw a graphical representation of a soundfile (a.k.a. waveform) onto a Canvas,
however I am not sure where to start.
I have used the SnackCanvas before (http://www.speech.kth.se/snack) and it is pretty cool,
however for several reasons I don't want to use the Snack package anymore and I wonder how
to achieve something like Snack's create_waveform() method in plain Tkinter.

Just in case you don't know exactly what I am talking about, a short description of what
SnackCanvas.create_waveform() does:

When called first on a soundfile, this file is scanned for peak values (which takes a while, on my box here
about 70 seconds for a 30 minute wav-file);
the information gained herein is then stored in a so called "shape file" (a binary file of unknown format,
which is about 600 kB for a 30 minute wav-file) which makes it very fast to load the waveform again later on (about one second).

The item returned by create_waveform() can then be treated like any other Canvas item;
especially cool features are, that with camvas.itemconfigure(item, height=...) you can stretch
the waveform vertically, and with canvas.itemconfigure(item, pixelspersecond=...) you can
"zoom" into the waveform horizontally, which is both pretty fast, too.

Now, trying to get something similar without Snack, I found there are several ways to scan the soundfile,
of which the most promising seems to me the audioop.maxpp() method. I tried to store the
information I get from audioop.maxpp() in a reasonable amount of time and ended with a 700 kB
text file filled with integer values, and there I am stuck.

Does anyone have an idea, if it is possible to put this information together to a usable Canvas item,
and if yes, where to go (polygon? image?).
Any ideas are much appreciated.

Thanks in advance.

Michael

You have two problems
1. Reading a sound file
2. drawing the waveform

I solved the 2nd problem only. This is a code that draws a random waveform.
---------------------------------------------------------------------------------
from Tkinter import *
import random
import math
import time

def fun(zoom=.1):
    t1 = time.time()
    global c
    # remove the old shapes.
    for item in c.find_all():
        c.delete(item)
    # calculate a random amplitude
    amplitude = random.random() * int(c.winfo_height()) / 2
    points = []
    for x in range(0, c.winfo_width()):
        y = math.sin(x * math.pi / (zoom*180)) * amplitude + int(c.winfo_height()) / 2
        points.append(x)
        points.append(y)
    #  now points should be of form [x0, y0, x1, y1, ...]
    # not [(x0, y0), ...]
    c.create_line(smooth=1, *points)
    c.update_idletasks() # to draw the shapes immediately.
    print 'Timing:', time.time() - t1
    
root = Tk()
c = Canvas(root, bg='beige')
c.pack(expand=1, fill=BOTH)
Button(root, text='Do waveform', command=fun).pack()
mainloop()
---------------------------------------------------------------------------------
It took 0.0310001373291 second to execute fun() in full-screen mode. 
I don't think customizing this will be a problem, but you know you can always ask.

Thanks Mohammad,

you are right, the line item looks very good.
The problem is that I have a real large number of coords here, so my 30-minute test file
at a resolution of 100 pixels / second takes more than 20 seconds to draw and then it sucks up more
than 20% of my computer's memory (says top).
I haven't tried zooming yet...

I think using an image may be a better chance, so I tried to use the canvas to create a postscript
that I could then convert into a gif, however the canvas wrote a 10 MB ps file that made convert crash
when trying to open it.

Any ideas?

Michael

What is the relationship you want to draw? frequency vs. time or what?
 frequency/time requires only 1 chart, but other relationships requires more than one, which may suggest using another widget.

the WCK allows you to draw directly from Python data structures:

It's peak level vs. time; the purpose of my app is to display the graphical representation of a (possibly very large)
soundfile to make it easy to determine track borders in e.g. a recorded vinyl album or tape cassette.
I am not sure if "waveform" is the correct term here, Snack calls it that way.
The screenshot at the bottom of <http://www.speech.kth.se/wavesurfer/screenshots.html> shows what it is supposed to
look like, however this one is only about two minutes wheras I need to draw much bigger soundfiles. The fact
that the gap between two tracks may be very short is why I need to be able to stretch it horizontally.

The reason why I don't want to use Snack anymore is that with Snack I had serious problems with simple audio
operations; I could still use Snack only for drawing the waveform, however Snack is a little
"unfriendly" when it tries to access the sound card, making it impossible to start the program
e.g. when esd or artsd are running (BTW, my app is supposed to run on linux only), that's why I
want to look for an alternative.

Thanks, I will check what mathplotlib and WCK can do for me (and probably come back with further questions later ,-).

Subject: [Tkinter-discuss] Hyperterm type program and text box
Message-ID: <20060123180653.2EEEA3AA515@ws5-8.us4.outblaze.com>

Hello,

I want to create a program to talk to the com port
(something like hyperterminal or minicom).  The display should be a
box that outputs characters as they come in (from the port), and
accepts characters as input, which it sends to the port.  Characters
entered on the screen should not be shown on the screen (which is the
default behavior of hyperterm and minicom).

I was planning on using the Tkinter Text widget for this, but see no
way of having the user enter data, without it showing up on the
screen.  Is there a way to do that?  Is there another widget that can
do it?  


Thanks,
Mike

Hi Michael,

you need to bind a special callback to the KeyPress events, like this one:

>>> from Tkinter import *
>>> root = Tk()
>>> text = Text(root)
>>> text.pack(fill=BOTH, expand=1)
>>> def keypress(event):
...     print event.keysym
...     return 'break'
... 
>>> text.bind('<Any-KeyPress>', keypress)

As you see in the example you can use the event.keysym attribute to catch the character
that would have been entered into the Text widget and the return "break" statement to
prevent the event from being delivered to the Text widget's insertion mechanism.

I hope this helps

Michael

I was afraid you might ask that  :  ).

I am working on an application that would allow an end-user to view
locally-saved web-pages and print them, if needed.  The viewer would not be
required to interact with the web.  However, all formatting (CSS, etc.)
would have to be maintained.  Web-pages would also generally include
images.  I definately would not require a full-fledged browser, just a
viewer that allows printing.

Am I oversimplifying here?  Should a different approach be taken, such as
converting the webpage to .pdf?


Thank You and Best Regards,

Christopher Nethery

Cameron, I see that mention is made of lwidgets, a new set of widgets
built from other widgets.  None of those have been added to Tkinter's
set of widgets, have they?

Off the top of your head, do you know of a good tutorial page for
someone wanting to create Tkinter wrappers for Tk widgets?

this existed in tcl.  At first glance, it looks like the HTML display
library with table support ('htmllib3_4.zip') might work, with a Python
wrapper.

I haven't found much yet on wrapper howtos--but Jeff Epler's PyBwidgets
wrapper seems as good a place as any to begin learning how to do this,
since the wrapper has so far worked elegantly for me.

Thank you for your help!

Hi Christopher,

pysol has a (very basic) html viewer to display its documentation (http://www.pysol.org/).
pysol is GPL'd, so if their html widget is good enough for you it's probably no problem for you to
use it.
It can display headers, horizontal lines, ordered and bulleted lists and (gif) images, but no advanced stuff like
tables or frames. I've used it for my own documentation and it works very well.

Michael

I know of no one who has systematically exposed Iwidgets in Tkinter.

I was sure one of had us written a page on exactly the subject
of wrapping Tk widgets for Tkinter.  I can't find it now, to my 
chagrin.  I'll return to this subject later in the week.

Michael,

That's great, thank you!  I'll check it out.  It may be all I need, if I
clip out all the unnecessary HTML from the pages or (if time allows)
enhance the viewer a little.  The pages I want to view are (relatively)
basic, since they contain few images and not a lot of 'fancy formatting'.


Thank you again and best regards,

Chris Nethery

Subject: [Tkinter-discuss] Catching exceptions
Message-ID: <43DEFB19.6000901@cogeco.ca>

ProgramA (a Tkinter application) contains this code snippet:

try:
     execfile('programB',{})
except:
     <code to handle the exception>

Where it runs programB.

ProgramA would like to catch and handle any otherwise uncaught 
exceptions in ProgramB. If programB is NOT a Tkinter application then 
ProgramA does indeed catch and handle exceptions that occur in programB. 
However, if ProgramB is a Tkinter application then virtually all the 
action takes place inside callbacks and any exceptions in those 
callbacks are caught and handled by Tkinter, thus never getting to 
exception handler in ProgramA.

Is there any way to tell Tkinter not to handle exceptions in callbacks 
so that on an exception in a callback programB would grind to a halt and 
the exception handler in ProgramA would take over? Or would this violate 
some fundamental principle of how Tkinter works?

Any knowledgable advice on this would be *greatly* appreciated.

Cam Farnell


If you are wondering what I'm up to, ProgramA is an (under construction) 
development environment which has produced ProgramB which we would now 
like to run. If execution of ProgramB goes badly we would like to show a 
traceback and then be able to take you to the offending line of code. 
But if Tkinter catches and hides the error, that's hard to do.

Here's a snippet I have laying around.  It doesn't exactly do what you
ask, but maybe it's a starting point.  You might see what the cited sf
tracker item is about as well.

# Print Tk errors to stdout. python.org/sf/639266
import Tkinter 
OldTk = Tkinter.Tk
class Tk(OldTk):
    def __init__(self, *args, **kw):
        OldTk.__init__(self, *args, **kw)
        self.tk.createcommand('tkerror', self.tkerror)

    def tkerror(self, arg):
        print "TCL error in asynchronous code:"
        print self.tk.call("set", "errorInfo")
Tkinter.Tk = Tk

In Python, you must write 'f()' to call the function f with no
arguments.  Perhaps you meant to write
    def znic():
        okno.destroy()

destroy() is the correct method to call to get rid of a widget.
