So I have this program which requests a file from the web and the user can download it. I am using urllib.request and tkinter for my program. The problem is that when the user hits the 'Download' button there is no pause or cancel until the file gets downloaded and the program freezes too. I really want to create a pause or a cancel button, but I do not know how and I want to eliminate the freezing of the program. Should I use another library like 'requests'? Or should I try threading? Can someone guide me through this?
My code(BTW if you know any way to improve my program I would appreciate it a lot if you shared it with me):

You can use reporthook option of urllib.request.urlretrieve() to associate a callback and abort the download by raising exception inside the callback:
downloading = False # flag to indicate whether download is active
def download_progress(count, blksize, filesize):
nonlocal downloading
if downloading:
downloaded = count * blksize
print('downloaded %s / %s' % (downloaded, filesize))
root.update() # let user interact with the GUI
else:
# user selects to abort the download
raise Exception('download aborted!')
# the download function
def download_image():
global formatname
nonlocal downloading
if downloading:
downloading = False
return
download_button.config(text='Stop!') # let user to click the button to abort download
downloading = True
if num.get() == 1:
name = random.randrange(1, 100000)
else:
name = str(name_entry.get())
formatname = str(format_entry.get())
'''if var.get() == 1:
operator = str(url_entry.get())
formatname = '.' + operator[-3] + operator[-2] + operator[-1]
else:
pass'''
fullname = str(name) + formatname
url = str(url_entry.get())
fw = open('file-size.txt', 'w')
file_size = int(requests.head(url, headers={'accept-encoding': ''}).headers['Content-Length'])
fw.write(str(file_size))
fw.close()
path = str(output_entry.get()) + "\\"
try:
urllib.request.urlretrieve(url, path.replace("\\", "\\\\")+fullname, download_progress) # added reporthook callback
except Exception as e:
print(e) # download aborted
else:
print('done')
download_button.config(text='Download!') # resume download button
The text of download_button is changed to Stop! after it is clicked so that user can click it again to abort the download. When the download is aborted/completed, its text is changed back to "Download!".

I'm trying to make a gui of a small project. I want to add the ability to once hitting add_item to add a data entry, it adds a time stamp to it as well. I'm very new to tkinter so any help would be great. I tried something like this:
tk.Button(root, text='add_item', command=lambda :text.insert("end", time.strftime("%d/%m/%Y%H:%M:%S")+'\n'))
b2.pack(side=tkinter.LEFT)
but couldn't get it to work with the rest of the code. I'm assuming it needs a lambda function, not sure how to set it up though.
import tkinter as tk
from datetime import datetime
import time
#1
now = datetime.now()
print ("Current date and time : ")
print (now.strftime("employee-attendance-list-%Y-%m-%d.csv"))

e.insert(0, time.asctime())
root = tk.Tk()
root.title("List App")
root.geometry("400x400")
def handler(e):
label= Label(win, text= "You Pressed Enter")
label.pack()

i want to build simple tkinter,
the GUI will display a text and user need to read the text and save the audio. my code currently works but the process not repeatable, my target when user press "NEXT" button the process will repeat the process... and when user press the "END" button process will stop.
is there anywhere how to done it?
import sounddevice as sd
import soundfile as sf
from tkinter import *
def Voice_rec():
fs = 48000
# seconds
duration = 5
myrecording = sd.rec(int(duration * fs),
samplerate=fs, channels=2)
sd.wait()
return sf.write('save_audio.wav', myrecording, fs)
master = Tk()
import os, random
txtfile = random.choice(os.listdir(""))
txtread = "" + txtfile
with open(txtread, "r") as filek:
textfile=filek.read()
# Label(master, text=filek.read()).pack()
wrapper = LabelFrame(master,text="sound record")
wrapper.pack(fill="both",expand="yes",padx=20,pady=20)
lbl3 = Label(wrapper,text=textfile,borderwidth=2, relief="solid",bg = "red")
lbl3.config(font=("Courier", 20))
lbl3.pack()
#def next():
# import os, random
# txtfile = random.choice(os.listdir("path"))
# txtread = "path" + txtfile
# with open(txtread, "r") as filek:
# textfile=filek.read()
# Label(master, text=filek.read()).pack()
# wrapper = LabelFrame(master,text="sound record")
# wrapper.pack(fill="both",padx=20,pady=20)
# lbl3 = Label(wrapper,text=textfile,borderwidth=2, relief="solid",bg = "red")
# lbl3.config(font=("Courier", 20))
# lbl3.pack()
Label(wrapper, text=" Voice Recoder : "
)#.grid(row=0, sticky=W, rowspan=5)
b = Button(wrapper, text="Start", command=Voice_rec)
b.pack()
c = Button(wrapper, text="Next", command=next)
c.pack()
#b.grid(row=0, column=2, columnspan=2, rowspan=2,
# padx=5, pady=5)
mainloop()
above code i refer from this link : https://www.geeksforgeeks.org/build-a-voice-recorder-gui-using-python/
I would suggest you wrap this in a function:
txtfile = random.choice(os.listdir(""))
txtread = "" + txtfile
with open(txtread, "r") as filek:
textfile = filek.read()
which you can then link to your Next button to load a new file each time. Do not re-render the whole UI every time.
In other words, something like this:
master = Tk()
text_file = StringVar()
wrapper = LabelFrame(master, text="sound record")
wrapper.pack(fill="both", expand="yes", padx=20, pady=20)
lbl3 = Label(wrapper)
def next_audio():
path = "path/"
txtfile = random.choice(os.listdir(path))
txtread = os.join(path, txtfile)
with open(txtread, "r") as filek:
text_file.set(filek.read())
print(text_file.get())
lbl3.configure(text=text_file.get())
next_audio()
lbl3.configure(text=text_file.get(), borderwidth=2, relief="solid", bg="red")
lbl3.config(font=("Courier", 20))
lbl3.pack()
Not the best looking code but that was not the intention, just to try and use your code to show what I mean. Also perhaps a tip on Tkinter, rather use the grid geometry manager. pack and place are not best practice with modern Tkinter.
Hope this helped?!
I am currently making a GUI with Tkinter that plays music. The program is able to correctly play the songs, and I am trying to implement a pause button. This is the code I have, does anyone know why this might not be working? I know the button is linked properly since I have tried printing something out when the button is clicked, and that works. Also, there are no error messages, the audio is just not pausing.

There is a class and class inside there is method called splash() so How can I create Thread, one for constructor and second for splash() method ?
Example with thread and other changes or comments in code because there are mistakes.
I didn't change from tkinter import * because it would need more work. On some systems thread may not have access to GUI so self.output in call_spash may have problem but I didn't change it - too many works.

This is probably a newbie question but I'm having issues figuring out how to get a value from a function, to be used as input in another.
I would also like to have some tips about code organization.
In this example I'm trying to get the filePath and outPut Folder path to be used in the function processFile.
Thank you
Code:
from tkinter import *
from tkinter import ttk
from tkinter.filedialog import askopenfilename
from tkinter.filedialog import askdirectory
import PyPDF2
from PyPDF2 import PdfFileWriter, PdfFileReader
version = "v0.0.01"
root = Tk()
def window (main):
main.title("File Opener " + version)
width = main.winfo_width()
main.geometry('500x200')
numero = str(1)
def OpenFile():
fileName = askopenfilename(initialdir="C:/",
filetypes =(("PDF File", "*.pdf"),("All Files","*.*")),
title = "Select PDF File",
)
labelName = Label(text="File Path: " + fileName)
labelName.pack()
print(fileName)
return fileName
def outputFolder(): #Bug, label keeps adding paths
outPath = askdirectory()
labelName2 = Label(text="Output Folder: " + outPath)
labelName2.pack()
print(outPath)
return outPath
def processFile(inFile,outFolder):
''' print(fileName) get input name and output variables
print(outPath)'''
label = ttk.Label(root, text ="",foreground="black",font=("Helvetica", 16))
label.pack()
#Button Open-----------
button1 = Button (text = "Open File", command = OpenFile)
button1.pack()
#Button Start---------
buttonStart = Button (text = "Start Process", command = processFile)#give as parameter inputFile and link
buttonStart.place(height=50, width=100)
#Button Open-----------
button3 = Button (text = "Output Folder", command = outputFolder)
button3.pack()
#Menu Bar ----------------
menu = Menu(root)
root.config(menu=menu)
file = Menu(menu)
file.add_command(label = 'Open', command = OpenFile)
file.add_command(label = 'Exit', command = lambda:exit())
menu.add_cascade(label = 'File', menu = file)
window(root)
root.mainloop()
If you use the function in a variable the returned result from the function is stored in the variable.
def Function1(x):
return x*2
var1 = Function1(5)
Then var1 = 10.
But about your buttons, do you want to take input from the user that will be saved when the button is pressed or do you want the button to send a set value?
from tkinter import *
from tkinter import ttk
from tkinter.filedialog import askopenfilename
from tkinter.filedialog import askdirectory
import PyPDF2
from PyPDF2 import PdfFileWriter, PdfFileReader
version = "v0.0.01"
root = Tk()
def window (main):
main.title("File Opener " + version)
width = main.winfo_width()
main.geometry('500x200')
main.configure(background = 'black')
numero = str(1)
#openFile
def OpenFile():
global fileName
fileName = askopenfilename(initialdir="C:/",
filetypes =(("PDF File", "*.pdf"),("All Files","*.*")),
title = "Select PDF File",
)
labelName = Label(text="File Path: " + fileName)
labelName.pack()
print(fileName)
return str(fileName)
#getOutputPath
def outputFolder(): #Bug, label keeps adding paths
outPath = askdirectory()
labelName2 = Label(text="Output Folder: " + outPath)
labelName2.pack()
print(outPath)
return outPath
#testFunct
def printFilename(inArg):
print(inArg)
x = OpenFile()
print (OpenFile())
lambda: printFilename(fileName)
#processRealDeal
def processFile(): #THIS IS THE MAIN FUNC
''' print(fileName) get input name and output variables
print(outPath)'''
print (OpenFile)
label = ttk.Label(root, text ="",foreground="black",font=("Helvetica", 16))
label.pack()
#Button Open-----------
button1 = Button (text = "Open File", command = OpenFile)
button1.pack()
#Button Start---------
buttonStart = Button (text = "Start Process", command = lambda: printFilename("Hello World!!!"))#give as parameter inputFile and link
buttonStart.place(height=50, width=100)
#Button Open-----------
button3 = Button (text = "Output Folder", command = outputFolder)
button3.pack()
#Menu Bar ----------------
menu = Menu(root)
root.config(menu=menu)
file = Menu(menu)
file.add_command(label = 'Open', command = OpenFile)

I cant see that you have declared the global fileName variabel outside the function.
I did this
from tkinter import *
from tkinter import ttk
from tkinter.filedialog import askopenfilename
from tkinter.filedialog import askdirectory
import PyPDF2
from PyPDF2 import PdfFileWriter, PdfFileReader
version = "v0.0.01"
root = Tk()
fileName = "test"
def window (main):
main.title("File Opener " + version)
width = main.winfo_width()
main.geometry('500x200')
main.configure(background = 'black')
numero = str(1)
#openFile
def OpenFile():
global fileName
fileName = askopenfilename(initialdir="C:/",
filetypes =(("PDF File", "*.pdf"),("All Files","*.*")),
title = "Select PDF File",
)
labelName = Label(text="File Path: " + fileName)
labelName.pack()
test()
return str(fileName)
#getOutputPath
def test():
print(fileName)
def outputFolder(): #Bug, label keeps adding paths
outPath = askdirectory()
labelName2 = Label(text="Output Folder: " + outPath)
labelName2.pack()
print(outPath)
return outPath
#testFunct
def printFilename(inArg):
print(inArg)
x = OpenFile()
print (OpenFile())
lambda: printFilename(fileName)
#processRealDeal
def processFile(): #THIS IS THE MAIN FUNC
''' print(fileName) get input name and output variables
print(outPath)'''
print (OpenFile)
label = ttk.Label(root, text ="",foreground="black",font=("Helvetica", 16))
label.pack()
#Button Open-----------
button1 = Button (text = "Open File", command = OpenFile)
button1.pack()
#Button Start---------
buttonStart = Button (text = "Start Process", command = lambda: printFilename("Hello World!!!"))#give as parameter inputFile and link
buttonStart.place(height=50, width=100)
#Button Open-----------
button3 = Button (text = "Output Folder", command = outputFolder)
button3.pack()
#Menu Bar ----------------
menu = Menu(root)
root.config(menu=menu)
file = Menu(menu)
file.add_command(label = 'Open', command = OpenFile)
file.add_command(label = 'Exit', command = lambda:exit())
menu.add_cascade(label = 'File', menu = file)
window(root)
root.mainloop()
And the test function prints the chosen file. So the global variable is now containing the correct value.
So just declare it at the top and you will be able to retrieve the value
