I would suggest embedding these widgets, and others, instead of trying
to replace the default behaviour of a cell entry in tktable.
Embedding is easy enough given your tktable python wrapper has the
window commands wrapped:

import Tkinter
import tktable

table = tktable.Table()
table.window_configure("2,3", window=Tkinter.Entry())
table.pack()

table.mainloop()

I'm using Tkinter.Entry here, but you could just as well use this
AutoCompleteEntry widget. This "2,3" is the cell index -- third row,
fourth column.
The wrapper I used there can be found at XXX (forgot the link, it is
on http://tkinter.unpythonic.net/wiki but the wiki is inaccessible
now) and also in tktable's cvs since about 1-2 month(s) ago (except
that the one in cvs doesn't yet have the latest updates).

It is a matter of reorganizing the ArrayVar associated to the table
since tktable doesn't have a built-in sort yet. Have you tried doing
anything like this ?

Dear Tkinter users/developers,

I'm just starting out in Python Tkinter programming, and I tried to use the
Tile module to improve the looks of the Tk program I am writing.

When I run the script written in <code></code> below, it works fine, using
the Tile module to make the Tk look ok. However, when I try to use
tkMessageBox.showwarning() as in the script, it fails with the error below.
I've tried to cat | grep for "background" in the files mentionned in the
error, but nothing turns up. I can't find where the "-background" switch is
getting stuck in. I know the "background" switch doesn't work with Tile, but
I can't find it to remove it. Any ideas please?

Thanks,

Nawal.

Subject: [Tkinter-discuss] Problem with grid layout
Message-ID: <4961EA4E.3060404@ill.fr>

Hello everybody,

I have a problem with the grid management.

Here is the following simple script:

######################################################################
from Tkinter import *
root = Tk()
f = Frame(root)
f.grid(row = 0, column = 0, sticky = W)

f1 = Frame(f, relief = GROOVE, bd = 2)
f1.grid(row = 0, column = 0, sticky = W)
str1 = StringVar(root,'%-20s' % 'Label')
Label(f1, textvariable = str1, anchor = W).grid(row = 0, column = 0, 
sticky = W)
Button(f1, text = 'Button1').grid(row = 0, column = 1)

f2 = Frame(f, relief = GROOVE, bd = 2)
f2.grid(row = 1, column = 0, sticky = W)
str2 = StringVar(root,'%-20s' % 'BiggerLabel')
Label(f2, textvariable = str2, anchor = W).grid(row = 0, column = 0, 
sticky = W)
Button(f2, text = 'Button2').grid(row = 0, column = 1)

root.mainloop()
######################################################################

I would expect that script to produce two frames with exactly the same 
size but it is not the case.
However the two labels have the same size by construction (i.e. 20).

Would you have any idea ?

thank you very much

Eric Pellegrini

strings of same length won't give you labels of same size, since that
matters nothing when you are not using a monospace font.
If you just want frames with same size, change theirs stickys to "ew".

to move every widget (In this case, 70 odd entry boxes, and a few labels)

Hi Waffles,

  Rather than using place() to put widgets within the canvas,
you need to actually draw them. Use the canvas method: create_window()

E.g., taking two of your lines:

    self.topic_label = Label(self.label, text='Topic:', font=15, bg='white')
    self.topic_label.place(x=16, y=8)

Should be:

    self.topic_label = Label(self.label, text='Topic:', font=15, bg='white')
    self.label.create_window(16, 8, window=self.topic_label, anchor=NW)

To get a scrollable canvas you will need to apply several tricks to
it. I would start suggesting by embedding a single frame at position
0, 0 on it, and then create all the other widgets using this frame as
the parent. Next you will need to wait the widgets appear (with
wait_visibility) and then adjust the scrollregion of the Canvas, as
well its width to something reasonable, and possibly how much the
scrollbars scrolls.

I'm leaving only the tips right now because I'm leaving right now.
Nevertheless, you can find several implementations of those through
Google.

I've just added a simple ScrolledFrame to
http://tkinter.unpythonic.net/wiki/ScrolledFrame

Don't be surprised if it doesn't work for you, it contains several
bugs in different categories :)
Improvements over time are likely to happen, especially if someone uses it.

Can you upgrade to 8.5 of Tk?  <URL:

I think the problematic part is this:

  root.tk.call('package', 'require', 'tile')
  root.tk.call('namespace', 'import', '-force', 'ttk::*')
  root.tk.call('ttk::setTheme', 'clam')

If I understand this correctly it will override the names of the core tk widgets with their themed
counterparts. So the file using the (no longer existing) "background" option is probably msgbox.tcl .
If you want to use tile you are certainly better off using Guilherme Polo's ttk module.

Is that safe? I thought Python 2.5 was not fully compatible with Tcl/Tk 
8.5.

For some values of Python 2.5, yes.
Python 2.5.3 should have no problems with it, but I can't really say
you are wrong because I (think) there was another issue related to
Python 2.5.x and Tk 8.5 but I can't remember. I will try to find it
now.

Just found it. If you have the privilege of being able to run an
own-compiled-version of Python (or, if possible, just update to Python
2.6), you could apply the following patch:
http://svn.python.org/view/python/trunk/Modules/_tkinter.c?rev=59653&view=diff&r1=59653&r2=59652&p1=python/trunk/Modules/_tkinter.c&p2=/python/trunk/Modules/_tkinter.c

That one wasn't backported to python 2.5, but I also don't remember
how to exactly hit the bug -- but will try reproducing it here (this
also remembers me of going back to finish the another python <->
tcl/tk bridge).

Ah, yes:

import Tkinter

text = Tkinter.Text()
text.insert('end', 'hi there')

def test(x):
    print x, type(x), "< bad"

text.tk.createcommand("test", test)
text.tk.call("test", text.bbox('1.0'))

x = text.bbox('1.0')
print x, type(x)

This is specially problematic in IDLE, but can affect other code too.
The problem is that bbox is supposed to return a tuple in Python,
which it returns, but then _tkinter (in Python 2.5) is not doing
proper object conversions in callbacks and you end up getting a string
in the example.

Trying a bit more I found this one:

import Tkinter

root = Tkinter.Tk()

print Tkinter.TkVersion

def test():
    return (1, 2, 3)

root.tk.createcommand("test", test)
x = root.tk.call("test")
print x, type(x)

With tk8.4 this returns a str, with tk8.5 and python 2.5.2 this
happens too, but with tk8.5 and python 2.6 it returns a tuple.
I believe this must cause trouble when using tk 8.5 specifically
because of other conversions errors, not this one alone, which didn't
happen with tk 8.4. To check something that gives you the problem, run
EditorWindow.py (in idlelib) then press 'a' and then tab for
autocomplete, it should hit the bug while using python 2.5 and tk 8.5.

I am relatively new to Tkinter and am finding some simple problems difficult
to understand/rectify

The following code displays two windows; my maximised application window and
a small window called Tk:


from Tkinter import *

class APP(Toplevel):
    def __init__(self, master):
        Toplevel.__init__(self, master)
        self.master = master
        
root = Tk()
app = APP(root)
app.state("zoomed")
app.title("Title")

root.mainloop()

I can fix this by inserting the line root.withdraw() after root = Tk() but
this seems like a clumsy solution to me. Could someone please help me
understand why two windows are being made

I can fix this by inserting the line root.withdraw() after root = Tk() but
this seems like a clumsy solution to me. Could someone please help me
understand why two windows are being made and suggest a better way to do
this.

Thanks,

I am relatively new to Tkinter and am finding some simple problems difficult
to understand/rectify

The following code displays two windows; my maximised application window and
a small window called Tk:


from Tkinter import *

class APP(Toplevel):
    def __init__(self, master):
        Toplevel.__init__(self, master)
        self.master = master
        
root = Tk()
app = APP(root)
app.state("zoomed")
app.title("Title")

root.mainloop()

I can fix this by inserting the line root.withdraw() after root = Tk() but
this seems like a clumsy solution to me. Could someone please help me
understand why two windows are being made and suggest a better way to do
this.

Dear Ru-D,

The following line makes one window:

> root = Tk()

And your other line makes another:

> app = APP(root)   (APP being a Toplevel window)

So the root.withdraw() is quite correct (many of us use it, that is if
we don't make use of the main window for the application itself).

Subject: [Tkinter-discuss]  How to set a constant in lambda
Message-ID: <21689312.post@talk.nabble.com>


I came across a problem that probably has a simple, clever, answer -- but it
is eluding me.  I was trying to create a set of tab buttons on a Tkinter
page using Buttons.  These are created dynamically when the user loads a
file.  I don't know in advance how many files will get opened, so I want to
have a variable number of tabs.

So we have a Frame T; and an array of tabs XT[]; and a function
switch_tabs(n) that will handle the details of switching the data base,
titles, etc.  I compute the tab number:

Whoopsie = len(XT)

And I create a new Button:

XT.append(Button(T,text="Viola:New Tab",command=lambda:
switch_tabs(whoopsie))

It all works fine except for this one minor detail.  Whoopsie can't be a
constant because I don't know in advance what constant to use.  And if
whoopsie is a variable, it apparently is evaluated at execution time, and
will have the then current value of whoopsie, not the value I wanted to set
at creation time.  I tried everything I could think of including
copy.copy(whoopsie) to get a constant set so that switch_tabs could know
which tab to switch to.

Couldn't do it.  I was starting to look at tracing back through stack frames
when it came to me that RadioButtons unlike generic Buttons have a
variable-value attribute pair that behaves as I desire.  So this
manifestation of the problem is worked around.  But I expect that I'll see
this problem again in some other guise.

Am I missing something?  Probably something simple?  What?

You could consider using a Notebook widget.

This makes my head hurts. Email's title was: "How to set a constant in
lambda", but you just said you don't want it.

Constants and variables do not exist at Python, they are all names.
Can I assume that by "constant" you mean a immutable type and by
"variable" a mutable type ?

You could have put better names for these things instead of "whoopsie,
Whoopsie" to help a bit. So, what is switch_tabs supposed to do ? And
how this 'whoopsie' thing affects it ? Does it move you to the latest
tab created ? If this is the case, you could consider a pre-defined
value like 'end' or even None maybe so switch_tabs can check for these
values and understand they mean: "move to the latest tab".

What do you desire ?

Message-ID: <ac2200130901271823q27fcd461r57a4d26976c796ee@mail.gmail.com>

Hello,

pyttk 0.3 has just been released! It is available at
http://pypi.python.org/pypi/pyttk/0.3
This release was supposed to have happened several weeks ago but I
ended up delaying it a lot, but well, finally it is here.

This one includes bug fixes, backward incompatible changes,
improvements and what not. Nothing really radical, but the changes are
there. For a full complete list of changes be sure to read
http://gpolo.ath.cx:81/posts/pyttk-03-released/ (if I haven't
forgotten anything).


What is this wrapper for ?
--------------------------------

This wrapper provides classes to allow using the Tk themed widget
set, which has been included in Tk 8.5 but can be used with earlier
versions if you have Tile installed. Ttk is based on a revised and
enhanced version of TIP #48 (http://tip.tcl.tk/48) specified style
engine.

What is Ttk ?
----------------

 The basic idea of ttk is to separate, to the extent possible, the code
implementing a widget's behavior from the code implementing its
appearance.
 Widget class bindings are primarily responsible for maintaining the
widget state and invoking callbacks, all aspects of the widgets
appearance lies at Themes.

Subject: [Tkinter-discuss] event_generate question
Message-ID: <49808DB3.FA48.005C.0@mdacorporation.com>

I'm trying to generate some events in Tkinter but it doesn't seem to be working the way I expected. Here's an example of what I'm trying to do...
 
def click():
  print 'click'
 
from Tkinter import *
top=Tk()
b=Button(top, text='Hit me', command=click)
 
b.event_generate('<Button-1>', x=0, y=0)
b.event_generate('<ButtonRelease-1>', x=0, y=0)
 
The appearance of the button changes after the <Button-1> event (to depressed), and again after the <ButtonRelease-1> event (to normal again), but the associated button command (the click function) is not called. If I bind a function for the event to the button using the bind method, it gets called, but I really need the associated command to get called too.
 
Also, I tried doing this with a Pmw.ScrolledListBox with an associated dblclickcommand, so I tried to generate <Double-Button-1> and <Double-ButtonRelease-1> events, but to my surprise, I received the following error message for both cases:
 
_tkinter.TclError: Double or Triple modifier not allowed
 
These problems are getting in the way of my attempt to automate GUI testing with Tk. Am I missing something?
 
(Ok, I really don't need the first case, because I can simple call the button's invoke method. But in the second case, the associated action is only invoked via the double click action.)

Weren't you the guy who found something else to run these kind of tests ? :P
If it is you then apparently my earlier email about taking a look at
the ttk tests got ignored, but it is fine.

You will want to generate an <Enter> event before those ones, also, if
your code is just that then also pack the button and wait for its
visibility before generating the events.

Well, it makes some sense. How do you double click something ? I'm
afraid you don't have a special key to double click, instead you just
click twice (if you happen to have one then it just simulates the
double click for you).

In resume:

import Tkinter

root = Tkinter.Tk()

def click():
    print "click"

def test(event):
    print "double"
    return "break"

btn = Tkinter.Button(command=click)
btn.bind('<Double-Button-1>', test)
btn.pack()
btn.wait_visibility()

btn.event_generate('<Enter>', x=0, y=0)
btn.event_generate('<Button-1>', x=0, y=0)
btn.event_generate('<ButtonRelease-1>', x=0, y=0)
btn.event_generate('<Button-1>', x=0, y=0)
btn.event_generate('<ButtonRelease-1>', x=0, y=0)

On the contrary, I looked into ttk and found it wasn't what I was looking for. We are doing full application black box test, not unit testing. Besides, using ttk would require a porting effort to an application we don't want to make any changes to. Instead, I decided to bite the bullet and create a layer that exposes Tkinter widgets to the AT-SPI world so we can use dogtail, LDTP, Accerciser, at-poke, or whatever. The new layer is called Tka11y (a11y = Accessibility).

Yes, my code did the pack (forgot to include it above), but I didn't know about the <Enter>. Adding this caused things to work. Thanks!

I tried this with the ScrolledListBox. Here's what I'm doing to simulate the double click. It seems to work fine.
 
    slb = Pmw.ScrolledListBox(top, dblclickcommand=click) # Same click() as above
    slb.pack() # I didn't forget this time :-)
 
    lb = slb.component('listbox') # Must generate event for subordinate listbox widget
    lb.event_generate('<Enter>')
    lb.event_generate('<Motion>',x=0,y=0) # Probably not needed, but it reflects reality more closely
    for i in range(2):
        lb.event_generate('<Button-1>',x=0,y=0)
        lb.event_generate('<ButtonRelease-1>',x=0,y=0)
    lb.event_generate('<Leave>') # For good measure
Notably, the event must be generated for the contained listbox widget. If the event is sent to the ScrolledListBox itself, it doesn't work.

After making the appropriate changes to Tka11y, I am now able to generate the double click from, for example, Accerciser and the application responses appropriately. Thanks for the help.
 
Is there any good documentation on the event system? I've been using http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm, but obviously, there's not enough detail, especially for event_generate.
 
BTW, I will be releasing Tka11y soon (within a few weeks). I've carved out a spot at http://tkinter.unpythonic.net/wiki/Tka11y (accessible from the front page). Stay tuned...

I never told you to move to ttk, just to look at its tests.
It doesn't matter if you are using unittest or not, what matters is
that it contains support functions like this one you are using, which
do not depend on ttk.

With lambda, you need to set the value of the variable at the time the 
lambda is created, or else the variable is grabbed from the environment at 
the time the lambda runs.  You can do this by using the variable as a 
default argument.  In your case, change:

XT.append(Button(T,text="Viola:New 
Tab",command=lambda:switch_tabs(whoopsie))

to

XT.append(Button(T,text="Viola:New Tab",command=lambda 
x=Whoopsie:switch_tabs(x))

ought to do it.

Ah, it looks like you got what he meant.

And to me, when you start having problem with lambda and solves it by
doing lambda bindings, that is a good time to move to real functions.

I also dislike lambdas for this purpose.  I'd recommend that the original 
poster build a class - many ways they could go with this, but here is one 
rough sketch (haven't checked for syntax errors, etc.):

class PageButton(Button):
        def __init__(self, master, text=None, page_number=0):
                self.page_number = page_number
                self.text = text
                if not self.text:
                        self.text = 'Page #' + str(self.page_number)
                Button.__init__(self, master, text=self.text, 
command=self.switch_tabs)
                self.master = master

        def switch_tabs(self):
                # do whatever is required to switch tabs here, using self 
to reference the button and self.page_number to reference the page

XT=[]

# command to create a new button
XT.append(PageButton(T, page_number=len(XT)))

Subject: [Tkinter-discuss]  Running system calls through TKinter
Message-ID: <21747662.post@talk.nabble.com>


Hi All,

I have been writing a little app in python/tkinter to allow non technical
users at my office setup/restore manipulate Oracle databases. I am using
cx_Oracle plugin as well.

The app works fine at the moment, doing everything I want it to. However
when it comes to importing a db I am just using imp.exe and dpimp.exe
basically making external system calls to run it. I know this is not ideal
and I should probably be using popen etc, but I am not to sure on how to get
it working. I tried a while ago and it broke more than it fixed so I paniced
and went back to good old command prompt method.

I want to be able to view the output of an oracle import in realtime, anyone
that has seen imp/exp knows that when running on command line you can see
the tables importing as they import line by line. Ideally I would like to
have a "process" tab on my tkinter app rather than a seperate DOS prompt
running the command, where you can see this execution.

I cant remember exactly what I tried before, but I think it involved using
popen and stdout and then printing stdout. However when I did it like this
it used to print out output in bulk blocks not nicely one line at a time. 

So.... Is there anyway to embed a command window inside a tkinter window, or
does anyone know a way of outputting system calls in to a tkinter window in
realtime, one line at a time.

I think I have explained my problem really badly, so sorry. I have searched
online and all I seem to get is the same use popen. Maybe I don't understand
the popen stuff well enough, but its time for another shot. This little DOS
prompt by the side of my app is getting on my nerves. 

Any Suggestions?, Im lost!

Many Thanks,

Matt

I don't think so, maybe something like powershell might be able. It
would be easy to do it with xterm, for example, since it has support
for a -into option.

Actually I think you did well explaining it ;)

Oh well, let me start it and someone with more Windows (got one of
these yesterday, so now I can at least test code there :) experience
can improve it. The code is ugly on purpose so you may resist to just
copy and paste it, and it is also an indication that it might not
work!


import subprocess
import Tkinter

from win32pipe import PeekNamedPipe
import msvcrt

root = Tkinter.Tk()

proc = subprocess.Popen(['c:/python26/python.exe', '-u', 'ex1.py'],
                       stdout=subprocess.PIPE)
out = proc.stdout

hndl = msvcrt.get_osfhandle(out.fileno())

def check_output():
    retcode = proc.poll()
    # using PeekNamedPipe to check for data available -- it returns immediately
    # (at least in single thread applications)
    _, avail, _ = PeekNamedPipe(hndl, 0)

    if avail:
        text.insert('end', out.read(avail))

    if retcode is not None:
        return
    else:
        text.after(100, check_output)

text = Tkinter.Text()
text.pack()
text.after_idle(check_output)

root.mainloop()


The sample used, ex1.py, is this one:

import time

print "hi"
time.sleep(2)
print "there"


Note that I have cheated by using a sample that happens to be a python
file and I "just happened" to run python in unbuffered mode. This is
where you will likely have problems, your .exe probably doesn't flush
after every single line. But hopefully this help you in some way.

I just noticed there is a win32process module included with pywin32,
so it must be possible. Better than that, there is something ready
already called pyconsole. It is found it here:
http://code.google.com/p/pyconsole/

I got it and tried doing an example with it:

import Tkinter
import pyconsole

class ConsoleProcessWindow(Tkinter.Text):
	def __init__(self, master=None):
		Tkinter.Text.__init__(self)

		self.console_process = pyconsole.ConsoleProcess('cmd.exe',
				console_update=self.console_update)

		self.last_line = 0

	def test(self):
		self.console_process.write('dir\n')

	def console_update(self, x, y, text):
		self.after_idle(lambda: self.update_text(x, y, text))

	def update_text(self, x, y, text):
		y += 1
		for i in xrange(y - self.last_line):
			self.insert('%d.0' % (self.last_line + i + 1), '\n')
		self.last_line = y
		self.insert('%d.%d' % (y, x), text)
		self.update_idletasks()


class App(Tkinter.Frame):
	def __init__(self):
		Tkinter.Frame.__init__(self)

		self.console = ConsoleProcessWindow(self)
		self.console.pack(side='left', fill='both', expand=True)
		vscroll = Tkinter.Scrollbar(orient='vertical',
				command=self.console.yview)
		self.console['yscrollcommand'] = vscroll.set
		vscroll.pack(side='right', fill='y')

		self.after(500, self.console.test)

root = Tkinter.Tk()
app = App()
app.pack(fill='both', expand=True)
root.mainloop()


And it works! So you just need to send things to this ConsoleProcess
like you would do in your typical command prompt.
