I have a class - code below - which works flawlessly when called from if __name__ == '__main__': but when I call it from another .py file it spits an error. Apologies if this is a basic mistake on my part, but I tried a LOT of stuff and nothing seemed to work, would really love some help!
The error:
File "c:\Users\...\test.py", line 6, in <module>
app = Screenshot(root)
File "c:\Users\...\Screenshot.py", line 18, in __init__
self.master_screen = Toplevel(root)
NameError: name 'root' is not defined
The Class:
import time
from tkinter import Toplevel, Canvas, Frame, BOTH, YES, Tk
import pyautogui
import datetime
class Screenshot():
def __init__(self, master):
self.master = master
self.rect = None
self.x = self.y = 0
self.start_x = None
self.start_y = None
self.curX = None
self.curY = None
self.master_screen = Toplevel(root)
self.master_screen.title("Fenify")
self.master_screen.attributes("-transparent", "blue")
self.picture_frame = Frame(self.master_screen)
self.picture_frame.pack(fill=BOTH, expand=YES)
self.createScreenCanvas()
#TakeScreenshot
def takeBoundedScreenShot(self, x1, y1, x2, y2):
...
#Window
def createScreenCanvas(self):

#Controls
def on_button_press(self, event):
...
def on_button_release(self, event):
...
def on_right_click(self, event):
...
def on_move_press(self, event):
...
#Exit
def exit_screenshot(self):
...
if __name__ == '__main__':
root = Tk()
app = Screenshot(root)
root.mainloop()
example of calling from another class:
import tkinter
from Screenshot import Screenshot
root = tkinter.Tk()
app = Screenshot(root)
root.mainloop()
