actually this can be done, at least with X11; here with debian I can do
something like:
from tkinter import *
from subprocess import Popen
root=Tk()
f=Frame(root, container=1, width=300, height=300)
f.pack(fill='both', expand=1)
pipe = Popen(('urxvt', '-embed', str(f.winfo_id(
root.mainloop()
Still, I am not so sure if this is a good idea.
First, those embedded windows can be tricky by themselves; there may also
be DE/WM dependent issues (no idea if this works on windows or OSX at
all).
Then you will have to consider user interactions with the terminal,
for example what if the user decides to simply type "exit" at the command
prompt? Or hits Ctrl+\ while the process is running?
Of course I do not know what you want to achieve in detail, but maybe if
you want to use a gui with tqdm it would be a better approach to catch
the string (I guess the "data" in your code snippet?) and instead of
printing it to stdout just putting it on a tkinter Label.
I don't know about tqdm, maybe you could change the output format a bit
to omit the progress bar at all, calculate the value for the
ttk.Progressbar with the percent value and put an output string like
47% 76442/161258.81970214844 [14:12<16:26, 86.00KB/s]
on a Label next to the progress bar. That would give the user all the
information they need, would be easier for you to handle, be more
reliable and surely make a better looking gui.

Re: [Tkinter-discuss] Help needed
Hi Michael,
Thanks for the help,It is useful.
I have a questions :
Cant we use tqdm progress bar in tkinter window ??
In other words, can't we get a terminal window in tkinter window; where
whatever the output of the code that is executed should be shown in the
terminal. like how we use in pycharm or cmd prompt in windows ...etc
Thanks
Bala

I have used the ttk.Progressbar with external shell commands; if you
don't necessarily need to use tqdm maybe you could use the same technique
for what you are doing.
I added a quick-and-dirty example how to do this below; in the example I
used the command "cdrdao disk-info" on linux, which when no disc is in
the drive will try for about 10 sec. to make sense of the non-existing
disc before giving up, printing "Unit not ready" to stderr for 10 times in
the process which I use here to draw the progress bar.
The gui remains responsive without having to use threads (as you can see
when you hit the stop button).
If you don't need any external command but just want to compare file
sizes, the code may become even simpler.
I hope this helps

[Tkinter-discuss] Help needed
Hi , I'm using following modules in python 3: import requests import os from tqdm import tqdm a piece of code from my script, requests.get(url, stream=True,allow_redirects=True) total_size = int(r.headers['content-length']) with open(SaveLocation + SaveFilename, 'wb') as f: for data in tqdm(iterable=r.iter_content(chunk_size=Chunk_size), total=total_size / Chunk_size, unit='KB', desc=SaveFilename): f.write(data) f.close() when I run the python file in terminal I get output as below : 47%|▋ | 76442/161258.81970214844 [14:12<16:26, 86.00KB/s] this progress bar I got it from a module called tqdm Now I'm planning to make UI, using tkinter with start stop button. but when I click start button I need the same tqdm progress bar output in the tkinter window could you please help me how to do it Thanks Bala ___ Tkinter-discuss mailing list Tkinter-discuss@python.org https://mail.python.org/mailman/listinfo/tkinter-discuss
Re: [Tkinter-discuss] help needed with radiobutton

Instead keep references to them around as in this example, which is a simple rewrite of your example. from Tkinter import * root=Tk() x=[] for i in range(10): x.append(IntVar()) if i 5: rb = Radiobutton(root, variable=x[-1], value=1, state=DISABLED) else: rb = Radiobutton(root, variable=x[-1], value=0, state=DISABLED) rb.pack() root.mainloop() By the way, are you sure you really want state=DISABLED?
