Hi I've learning tkinter on python3 and I'm trying to use multithreading on tkinter to open a few windows also base on tkinter, but it seems that it can only open the first window and the second appears only after closing the first window. I use multithreading is to avoid a followed window being blocked by the previous, but it still seems happened. Here's part of my code and I replace the if statements with if something happened:
from tkinter import *# GUI window
import os
import _thread
top = Tk()
top.title("Test")
def pressbutton(count):
if count <= 10:
print(count)
count += 1
if count < 10:
_thread.start_new_thread(pressbutton,(count,))
if something happened:
os.system("python t1.py")
if something happened:
os.system("python t2.py")
startButton =Button(top, text="Start", command=lambda: pressbutton(0))
startButton.grid(column=0, row=1)
t1.py and t2.py are two python files that also build with tkinter. What I'm trying to get is to have several t1 and t2 windows, but only one appears.

I'm making an tkinter app. I have 2 scripts and I have to make an GUI where you can press one button and scripts will be run in sequence. Also I should note that my scripts also use tkinter.
I tried to make it just by making 2 functions for each script and putting them in one button, but it doesn't work right. It's only open window of first script and second one starts only if I close both open windows.
This is what i tried
import tkinter as tk
from tkinter import ttk
def run_script_1():
# Code for running script 1
print("Running script 1")
def run_script_2():
# Code for running script 2
print("Running script 2")
def run_both_scripts():
run_script_1()
run_script_2()
root = tk.Tk()
root.title("Script Runner")
root.geometry('600x100')
frame = ttk.Frame(root)
frame.pack()
button = ttk.Button(frame, text="Run Both Scripts", command=run_both_scripts)
button.pack()
root.mainloop()
script_a.py
from tkinter import *
from script_b import test
root = Tk()
var1 = stuff
var2 = stuff
def start_scriptb():
test([var1, var2])
Button(root, text="Start",
command=start_scriptb)
root.mainloop()
script_b.py
from tkinter import *
def test(x):
main = Tk()
Label(main, text=x)
Button(main, text="Exit", command=main.destroy())
main.mainloop()
This is a very basic version of what I'm trying to achieve. I actually am spawning a progress window that uses subprocess.Popen in script 2 with the passed through variables from script one and viewing the progess through a scrolled text widget on the 2nd program. I'm trying to spawn a new process, independent from the root GUI each time that button is hit from script_a.
It works fine in my tests so far, but I wanted to see if this could cause any issues or if this is actually spawning two processes?
I know there should only be one Tk() per process.
Using a TopLevel() window to show the progress works fine with the threading module, but the TopLevel() window will freeze as well as root (and any other open TopLevels()) if root is doing any sort of processing that takes any length of time.
With many hours of testing, I did have success in running two Tk() loops, but it had potential to be problematic, as "Bryan Oakley" had posted in many threads about.
Ultimately, I decided when I was in need of running something alone, I'd start my GUI with arguments and process it in an entirely new process instead of passing any arguments directly. Seems like a safer option.
I am running my performance test on python and I want to call some Tcl commands using Tkinter inside my python script.
Can somebody please help me to write the code,
import Tkinter
root = Tkinter.Tk()
root.tk.eval('puts {printed by tcl}')
I tried simply above example, here when I do root=tkinter.tk() it opens up a window, I just want to execute my command and get the result
The code you have tried will not show any window until you put the root.mainloop(),but you can try something like this,
import tkinter
root = tkinter.Tk()
root.withdraw()
root.tk.eval('puts {printed by tcl}')
root.destroy()
root.mainloop()
here withdraw() will remove the window from the screen without destroying it and then you can perform your tasks and then destroy it at the end of code.
This is my first question.
I have a python program that recognize voice and reply with voice.
I wish to add a little GUI for my program (it should have only an image on background and a button to quit the program)
I would like that when I launch my code from terminal, it opened a Tkinter window and at the same time the python program start.
I’m working on Mac Os.
I use speech_recognition package to recognize voice and I use NSS speaker to let my computer speak.
This is a example of my code:
import speech_recognition as sr
from AppKit import NSSpeechSynthesizer
#VARIABLES
L = sr.Recognizer() #LISTENING
nssp = NSSpeechSynthesizer #SPEAKING
S = nssp.alloc().init()
while True:
audio = L.listen(source)
s = L.recognize_google(audio, language="en-US")
if s == "hi":
S.startSpeakingString_("Hello!!!")
Where do I have to write the Tkinter instructions to make sure that when I run my code it opens only a Tkinter window (while my program goes on) and not a shell's one?
You'll find it difficult to introduce your GUI as your code has already been written, note that everything in Tkinter has to be stored in some sort of Label or Widget and so you can't just print what you already have onto the Tkinter screen.
Here is some code to create a basic Tkinter window. Try searching online and playing around with how to present your variables within said window
import tkinter
from tkinter import *
root = tkinter.Tk()
root.configure(background = "#66ffdd") #here you can use any hex color code or just leave it blank and configure as default
root.title("Voice Program") #use the name of your program (this is the window header/title)
root.geometry("800x500") #these are your window dimensions
welcome = tkinter.Message(root, text = "Welcome to my program")
button = tkinter.Button(root, text="This button", command=print("hello")) #here insert a function for the button to perform i.e quit
welcome.pack()
button.pack() #packing presents your variables to the window - you can also use other geometry managers like grid
This site is really useful for showing you what widgets are available and what you can do with them - try searching any issues or posting a more specific question in the future if you struggle.

I am trying to get keypresses in Python (2.7.10), bit I had no luck with getch(), as ord(getch()) was returning 255 constantly, so I am now using Tkinter. (I believe that Tkinter is also cross-platform so that should help as i plan to run this script on a Linux device).
I need to be able to get keypresses, even if they are not pressed while the Tkinter window is not active.
Here is my code:
from Tkinter import *
import time, threading
x = "Hi!"
def callback(event):
x = "key: " + event.char
print(x)
def doTk():
root = Tk()
root.bind_all("<Key>", callback)
root.withdraw()
root.mainloop()
thread1 = threading.Thread(target=doTk)
thread1.deamon = True
thread1.start()
I am not reveiving any errors, it is not not registering keypresses. I have also tried this without using threading, but it still does not work.
Please also note that I cannot use raw_input() as I need this to be able to run in the background and still get keypresses.
I am aware that this does not produce a frame, I do not want it to.
Thanks in advance for any help :)
PS: I have looked to other answers on StackOverflow and other sites, but they all either don't work or give solutions where keypresses are only registered when the tkinter frame is active.
