I'm going to reply to the three messages in this one post.

< at >Kevin: Thank you very much, Kevin! I had good memories with BWidgets on Tk
about 10 years ago (wow). Hope it now has even more to offer with tkinter.
I'm also curious about the performance and stability of the extensions.
Would they perform well with basic widgets together?


< at >John: I'm interested in some specialized widgets I saw in other toolkits,
such as the "rating"  widget (NSLevelIndicator) in Cocoa.

< at >Alejandro: It sounds like a good idea to have an RAD tool for designing
widgets. I gave it a quick look. Does it support only python 3.2+(?) or is
it just that it requires py3.2 to run the toolkit itself but it can also
generate py2 stuff?

Thanks again to your input,
Beinan

Hello Beinan,

Maybe you can use Pygubu [1], a GUI builder that I'm working on, to
build more complex widgets in a "easy" way.
Includes the basic ttk widgets and some helpers and is inspired in Glade.

I'm not familiar with Tkinter extensions, but here is a quick

The ttk module does include Notebook and Treeview and a few other

Hi Benian,

Tkinter indeed has a lot of extension packages. The Tkinter wiki is very 
hit-or-miss in listing and documenting them, however.



PMW is somewhat outdated but still seems to be used in a lot of legacy 
Tkinter apps. It is a pure-Python package and thus is easy to install 
and use.


Tix is a binary (compiled) Tk extension with a Python wrapper. It is a 
pure legacy extension that is now little used in the Tcl/Tk world. It 
needs to be installed as part of Tcl/Tk before you can access it from 
Tkinter.



Zinc is an enhanced Tkinter canvas extension that is, AFAIK, no longer 
developed.

    *

I think this is a long-abandoned project of Frederick Lundh that he 
never bothered to remove from his website.



This page is not a list of extensions per se but documents how you can 
call into Tcl/Tk and access the functionality of Tk extensions written 
in Tcl even if they do not have a Python wrapper. This is very valuable 
knowledge to have--it is how I access a wide range of Tk packages in my 
apps

Hi Tkinter,

As far as I understand, I assume ttk has quite a number of high-level
widgets such as notebook,
but the inventory is still not as big as one may find in other toolkits

No, music.play() is not supposed to block. However, I haven't tried to use

there isn't a pygame event loop running.

I never used pygame myself, so I can only guess that the pygame method

If this is the case, you will have to use a background thread to
do the playback. This is not necessarily overly complicated and perfectly
safe as long as you make sure that the tk gui runs in the main program
thread and that you must never do any calls to tk methods from within any
of the child threads; see here:
http://code.activestate.com/lists/python-tkinter-discuss/3138/
for a (however quite primitive and useless) example of a basic technique
for setting up threaded Tkinter programs.

Otoh, if you only need some simple audio playback and not necessarily
require pygame, there might be other python libs available that can
handle this, for example iirc tkSnack (http://www.speech.kth.se/snack/)
supports non-blocking playback (though tkSnack today is rather dated,

Button Press Freezes

Quaki Gaffar — 2013-05-15T10:01:32

Here's my situation. I have two tkinter buttons:

    Play Button: plays a sound
    Stop Button: to stop the sound during play

Code is as follows:

def Play(self):
    //plays a file with pygame module

def Stop(self):
    //Stop using pygame stop


Button( root, text ='Play', command= Play).pack()
Button( root, text ='Stop', command= Stop).pack()

The issue is that, when I click the 'Play' button, it stays pressed until it completes playing the sound, freezing the entire program, not allowing me to press 'stop' button during that time.

How do i prevent the program from freezing while the play is in progress to allow me to do other things like stop?

 i tried a suggestion proposed here, but it does not work.

Any ideas would be greatly appreciated :)

Hello Python Developers

I am working on an application that should support the Multiple documents

questions below

1) using a container that suits MDI ( Frame or Canvas or anything else).

2) When button pressed for option1 one then show option1 and when button
pressed for option2 show option2 and when again pressed for option1 it
should come up as the front window.

3) The following wrapper should also support as an image holder like canvas
or can hold the canvas to show the images.

I'm working on a simple gui builder for tkinter similar to Glade (the

It is Not finished yet and there is little documentation.

However, I invite you to try it and comment or make suggestions. There
are some examples that you can follow.

I named it pygubu, the code is here:

Hmm, I think however that the usage of "state" in the heading command,
where you can do e.g.:

   % .t heading 0 -anchor e state disabled -text foo

is probably at least rather counter-intuitive even for tcl programmers. In
this context "state" (at least to me) clearly looks like an option, not
like a command and should therefore be preceded by a "-".

And since the state option for the heading command is not documented in
the treeview man page its behavior might still be a subject to be
changed, so I doubt if it makes much sense to add a workaround to ttk.py
now.

Hi Jeff,

I don't think you're correct on this point.

The ttk widgets handle some things differently than the standard Tk 
widgets. According to the man page (of Tk 8.5 at 
http://www.tcl.tk/man/tcl8.5/TkCmd/ttk_treeview.htm, with the ttk 
widgets, "state" is a command rather than a configuration option:

pathname state ?stateSpec?
Modify or query the widget state; see ttk::widget(n).

Therefore, rather than Tk being wrong, Python is doing the wrong thing 
by mangling the command.


For what it's worth, here is the core repo for Tcl/Tk now: 
http://core.tcl.tk.  The project shifted its SCM from CVS to Fossil 
(http://fossil-scm.org/) about a year ago.

I do understand the confusion. In the ttk widget C code, "state" is 
grouped among the configuration options, and its purpose is to set 
configuration, but it does so as a command, not as a flag passed to the 
"configure" command. I'm not sure why it was implemented this way, but 
that does appear to be its design. Perha

Re: Strange 'tate' option in ttk.Treeview.heading

Jeff Epler — 2013-04-11T12:32:40

This is an upstream bug in Tk which appears to still be present in their
development version.  There's supposed to be a "-state" property of
treeview columns, but the "-" is missing.  Python always removes the
first character in its configure-type interfaces, so you get "tate"

Compare the definition of "-text" to "state" at lines 296 and 308:
http://tktoolkit.cvs.sourceforge.net/viewvc/tktoolkit/tk/generic/ttk/ttkTreeview.c?revision=1.41&view=markup#l295

$ wish8.5
% ttk::treeview .t -columns A
.t
% .t heading 0
-text {} -image {} -anchor center -command {} state {}
% .t heading 0 -state {}
unknown option "-state"
% .t heading 0 state {}
% 

I did not immediately find a bug about this in the tktoolkit bug
tracker.  Please consider filing one if you hope for it to be fixed.

Hello,

root = tk.Tk()
columns = ('A', 'B', 'C')
tv = ttk.Treeview(root, columns=columns )
for col in columns:
    tv.heading(col, text=col)
tv.heading('#0', text='Root')
tv.grid()

#get heading properties
properties= tv.heading('A')
# Print strangeous 'tate' property
print("strange 'tate' option", properties)
properties['anchor'] = tk.E

#error trying to set properties
tv.heading('A', **properties)

root.mainloop()
