Get icon of root window to be used by second window tkinter

I was wondering if there is anyway to get the ico file of one window and use it in the same window, without getting to know the icon location.
from tkinter import *
root = Tk()
root.iconbitmap('img/icn.ico')
top = Toplevel()
root.mainloop()
Here I want top to have icon of root without saying top.iconbitmap() or top.iconphoto(), the closest ive got is top.tk.call('wm','iconbitmap') but I dont know what is to be done with this as i couldnt find a understandable documentation.
Why dont I want to use iconbitmap(), its basically that, with tkinter.messagebox you can see the messagebox automatically inherit the icons from the parent widget. I was trying to duplicate this effect. Where if the icon is the default tk icon, then show blank icon or else show the custom icon.
Thanks in advance :D

[I'm using links into the core Tk documentation here. It's much more accurate than the Tkinter docs for most things, and Tkinter is mostly an obvious thin wrapper around it.]
You don't want wm iconbitmap. That's been effectively obsolete for decades; it uses an object class — bitmap — that's not relevant these days as it is monochrome and uses the weirdest format. (Filenames need to be preceded by # to make them work.)
Instead, you want to manipulate the wm iconphoto of the toplevel windows concerned. These take true photo images (there are many image file formats you can load into them) and you can share them easily.
# Load the image from the file; can also use PNG and other formats
my_image = PhotoImage(file="image.gif")
# Apply the image as the icons
first_toplevel_window.iconphoto(False, my_image)
second_toplevel_window.iconphoto(False, my_image)
Note that how the icon is displayed can vary wildly; it's not under your control.

You can use iconphoto() and set the first argument to True, then the same icon will be used for future created toplevels as well:
import tkinter as tk
root = tk.Tk()
icn = tk.PhotoImage(file='my-icon.png')
root.iconphoto(True, icn)
top = tk.Toplevel(root)
root.mainloop()

If you use the default instead of the bitmap (or first) argument, the icon will automatically be used on all TopLevel windows:
root.iconbitmap('img/icn.ico') # icon set only on root
root.iconbitmap(bitmap='img/icn.ico') # same as above
root.iconbitmap(default='img/icn.ico') # icon set on root and all TopLevels

Disable window move in Tkinter Python

it seems that I was pending to continue the bombardment of questions. It this is short, Is it possible to disable the movement of the Tkinter window without deleting the top bar of this?
It would give a minimal and reproducible code, but if it did it would only be two lines, it would be useless.

Bind a event for your window,and set the window .geometry()
But now you can not revise the window size by dragging the window's border(But it can maximize the window.).
Here is an example of the code:
import tkinter
def GetWindowPos():
global X,Y
X = win.winfo_geometry().split("+")[1]
Y = win.winfo_geometry().split("+")[2]
win.bind_all('<Configure>', HoldOn)
def HoldOn(event):
win.geometry("+{}+{}".format(X,Y))
win = tkinter.Tk()
win.geometry("400x400+{}+{}".format(12,12))
tkinter.Label(win,text="Halo!").grid()
win.after(100,GetWindowPos)
win.mainloop()

I have found a method, but as you might know to achieve something, we have to lose something!
You can use:
root.overrideredirect(True) # turns off title bar
by which you wont be able to move the tkinter window and also Tkinter application won't be displayed in taskbar, but you will also lose the title bar.
but if you wish to have the title bar,
then you can create one by this link.
Or use below to make a new title bar and also be able to move it(from this answer)
def move_window(event):
root.geometry('+{0}+{1}'.format(event.x_root, event.y_root)
# bind title bar motion to the move window function
title_bar.bind('<B1-Motion>', move_window)
But still your Tkinter application won't show up in taskbar, here's a solution(from this answer):
root = tkinter.Tk()
top = tkinter.Toplevel(root)
root.attributes("-alpha",0.0) # to make root invisible
#toplevel follows root taskbar events (minimize, restore)
def onRootIconify(event): top.withdraw()
root.bind("<Unmap>", onRootIconify)
def onRootDeiconify(event): top.deiconify()
root.bind("<Map>", onRootDeiconify)
You can add a toplevel window under the root object, make toplevel invisible and then handle the icon events of top level to hide or show the root window on taskbar.

Drag and Drop button tkinter python

I'm new using tkinter on python and I would like to develop a program that can Drag and Drop a button pressing other one... I will try to explain : I have button 'A' that will create a new button 'B' and I want to Drag the New button to another place
Any help
Thanks

The tkinter.dnd module, as suggested by j_4321 in comments.
Here is some sample code using that library to do what you have said:
from tkinter import *
from tkinter.dnd import Tester as DragWindow, Icon as Dragable
# Make a root window and hide it, since we don't need it.
root = Tk()
root.withdraw()
# Make the actual main window, which can have dragable objects on.
main = DragWindow(root)
def make_btn():
"""Make a new test button."""
# The functional part of the main window is the canvas.
Dragable('B').attach(main.canvas)
# Make a button and bind it to our button creating function.
Button(main.top, text='A', command=make_btn).pack()
# Start the mainloop.
mainloop()

How to remove title bar in Tkinter program?

I am working on a project using Tkinter library for making a GUI. This GUI will be displayed on a touch screen using raspberry pi 3.
I want to prevent user from exiting or minimising the program.
Is there any way to disable or remove the title bar? Or is there a better way to achieve this?

Since you mentioned a raspberry pi I suppose you are using Linux. In this case you can use root.attributes('-type', 'dock') (assuming your Tk instance is called root). This way, your window will have no decoration (so no close or minimize buttons) and will be always on top. If you don't want it always on top, you can use type 'splash' instead. In any case, you will need to use focus_force to be able to get keyboard focus.
import tkinter as tk
root = tk.Tk()
root.attributes('-type', 'dock')
root.geometry('200x200')
tk.Entry(root).pack()
root.focus_force()
root.mainloop()
Otherwise, you can prevent the window from being closed by setting the 'WM_DELETE_WINDOW' protocol and redisplay the window each time it is minimized:
import tkinter as tk
root = tk.Tk()
def unmap(event):
if event.widget is root:
root.deiconify()
root.protocol('WM_DELETE_WINDOW', lambda: None) # prevent closing
root.bind('<Unmap>', unmap) # redisplay window when it's minimized
root.mainloop()

root = tk.Tk()
root.wm_attributes('-type', 'splash')

Tkinter overrideredirect no longer receiving event bindings

I have a tinter Toplevel window that I want to come up without a frame or a titlebar and slightly transparent, and then solid when the mouse moves over the window. To do this I am using both Toplevel.overrideredirect(True) and Toplevel.attributes('-alpha', 0.75). I am binding the <Enter> and <Leave> events to a function for this.
These all work when tried separately, but when I have the overrideredirect set to True, the bindings for the mouse entering and leaving no longer works. The binding calls when I click on the window, and then when I move the mouse, but not when the curser enter or leave the window.
I have also tried binding these to a Frame, but with no further luck.
toplevel = Toplevel(root)
toplevel.overrideredirect(True)
toplevel.attributes('-alpha', 0.75)
toplevel.bind('<Enter>', lambda x: mouseMovement(command='enter'))
toplevel.bind('<Leave>', lambda x: mouseMovement(command='leave'))
def mouseMovement(command):
print('Callback: ' + command)
if command == 'enter':
toplevel.attributes('-alpha', 1)
elif command == 'leave':
toplevel.attributes('-alpha', 0.75)
I have tried using the answer to the similar question here, but this results in a window that has all the standard OS decorations, but the close, minimise, and enlarge buttons are simply disabled. Is there a way where I can get rid of the titlebar, but still keep my bindings?

On X Windows this can be handled using appropriate Extended Window Manager Hints to request the window manager to decorate the toplevel the way desired. This sounds like a splash screen window so 'splash' is likely to be appropriate here. For this use the wm_attributes -type parameter eg:
toplevel.wm_attributes('-type', 'splash')
will have the toplevel decorated as for a splash screen dialog which usually means no title bar. If you apply this to an already mapped window, you will need to withdraw and re-map (call wm_deiconify) to get the window manager to apply its settings for the new hint type.
