My code is designed to take an image off of the webcam, display the image, read the RGB colors from multiple pixels OpenCV and then plot those points in a graph (matplotlib). It all works, but I want to have the image, the graph and the buttons all in the same window, instead of three separate windows. Can anyone help?
Here is my code.

I wrote a CAD coordinate conversion application that reads a .txt file using filedialok.askopenfilename() using the function read_file_click().
After selecting the appropriate scale in the Combobox, the program converts the file using the convert() function, then saves it to a .txt file after calling the function save_file_click().
The problem is that when I send the returned value from the convert function to the save_file_click() function, I get two notifications about opening the file.
I don't know how to correct this error. I tried using global variables, but it doesn't help, and weak errors appears with the data_list_no_head variable. Thanks for help:)

I am trying to record my desktop screen and record the audio from microphone simentensously with the help of this python script.
Now when i run only the screen capture part the code works perfectly fine but when i try to run both sound recording and screen capture combine code as shown in below code. my video and audio both file does not open. (0 bytes) or very less size file.
How can i solve this problem.
updated Code
now i am able to record voice properly but the video file is not opening?

Suppose I have 'n' image files in a directory filedir which I want to view via tkinter console. Now, I want to skip a few files whenever necessary, using a button click event which invokes a function nextFile().
E.g.
import os
def nextFile():
global img
img_2 = process(img)
return img_2
window = tk.Tk()
window.title("File Viewer")
files = os.listdir(filedir)
button1 = tk.Button(window, text="Browse Files...", fg="black", command=askopenfilename)
button2 = tk.Button(window, text="SELECT", width=50, command=nextFile)
canvas = tk.Canvas(window, width=width, height=height)
button1.pack(side=tk.LEFT)
button2.pack(side=tk.BOTTOM)
canvas.pack()
for f in files:
img = cv2.cvtColor(cv2.imread(filedir + '/' + f), cv2.COLOR_BGR2RGB)
photo = ImageTk.PhotoImage(image=Image.fromarray((img))
canvas.create_image(0, 0, image=photo, anchor=tk.CENTER)
window.mainloop()
Any help is appreciated. Thanks!
Here is a simple example using PIL to load the inital image and then use a button and function to load each next image.
import tkinter as tk
from PIL import ImageTk, Image
import os
path = 'C:/your/file/path/here'
def nextFile():
# the global is needed to keep track of current index and also keep
# a reference of the image being displayed so its is not garbage collected.
global current_ndex, image
current_ndex += 1
if current_ndex < len(files):
img = Image.open('{}/{}'.format(path, files[current_ndex]))
image = ImageTk.PhotoImage(img)
# clear the canvas before adding the new image.
canvas.delete("all")
canvas.create_image(0, 0, image=image, anchor=tk.CENTER)
my_window = tk.Tk()
my_window.title("File Viewer")
files = os.listdir(path)
current_ndex = 0
button2 = tk.Button(my_window, text="Next", width=50, command=nextFile)
canvas = tk.Canvas(my_window, width=100, height=100)
button2.pack(side=tk.BOTTOM)
canvas.pack()
first_image = files[0]
img = Image.open('{}/{}'.format(path, first_image))
image = ImageTk.PhotoImage(img)
canvas.create_image(0, 0, image=image, anchor=tk.CENTER)
my_window.mainloop()
I'm trying to do a Canvas that display a picture in a new window with a pressing a button, actually that is working, but I need the display that show the image in the new windows resize to the new window dimension.
I already tried to manage to get the size to an specific but nothing really worked out for me.
