I'm new to Tkinter and while experimenting with it, I hit a problem, The color of the cascade menu could be changed easily but the border cannot be removed. Is there a cross platform way to do it? I want the border to be either of the same color as background or be removed. [Here's the snippet][1]
from tkinter import*
root= Tk()
root.configure(bg="#20232A")
root.geometry("500x500")
menubar = Menu(root)
File= Menu(menubar, tearoff = 0, bg="#20232A", fg="#ffffff", bd=0)
File.add_command(label="New File Ctrl+N")
File.add_command(label="New Window Ctrl+Shift+N")
File.add_separator()
File.add_command(label="Recent ")
File.add_command(label="Open Ctrl+O")
File.add_separator()
File.add_command(label="Save Ctrl+S")
File.add_command(label="Save as Ctrl+Shift+S")
File.add_separator()
File.add_command(label="Quit Alt+F4")
menubar.add_cascade(label="File", menu=File)
root.config(menu=menubar)
root.mainloop()
