Make tkinter Window appear in the taskbar

Question

I\'m making a music player GUI and I can\'t make it appear on the taskbar or in Alt-Tab. I have set overrideredirect() to true to remove the borders and the title. I also ma

Answer 1

after a bit of research i have found that there is a way to do this, but it involves using ctypes and is a windows only solution:

import tkinter as tk
import tkinter.ttk as ttk
from ctypes import windll

GWL_EXSTYLE=-20
WS_EX_APPWINDOW=0x00040000
WS_EX_TOOLWINDOW=0x00000080

def set_appwindow(root):
    hwnd = windll.user32.GetParent(root.winfo_id())
    style = windll.user32.GetWindowLongW(hwnd, GWL_EXSTYLE)
    style = style & ~WS_EX_TOOLWINDOW
    style = style | WS_EX_APPWINDOW
    res = windll.user32.SetWindowLongW(hwnd, GWL_EXSTYLE, style)
    # re-assert the new window style
    root.wm_withdraw()
    root.after(10, lambda: root.wm_deiconify())

def main():
    root = tk.Tk()
    root.wm_title("AppWindow Test")
    button = ttk.Button(root, text='Exit', command=lambda: root.destroy())
    button.place(x=10,y=10)
    root.overrideredirect(True)
    root.after(10, lambda: set_appwindow(root))
    root.mainloop()

if __name__ == '__main__':
    main()

this involves using ctypes to manipulate the windows style, however you need to use the right Get/Set functions depending on the applications environment. for 32 bit windows it seems you need to use either:
GetWindowLongW and SetWindowLongW
or
GetWindowLongA and SetWindowLongA

but 64 bit needs:
GetWindowLongPtrW and SetWindowLongPtrW
or
GetWindowLongPtrA and SetWindowLongPtrA
see this

or alternatively, if you want this behaviour by default:

import tkinter as tk

from ctypes import windll

class Tk(tk.Tk):
    def overrideredirect(self, boolean=None):
        tk.Tk.overrideredirect(self, boolean)
        GWL_EXSTYLE=-20
        WS_EX_APPWINDOW=0x00040000
        WS_EX_TOOLWINDOW=0x00000080
        if boolean:
            print("Setting")
            hwnd = windll.user32.GetParent(self.winfo_id())
            style = windll.user32.GetWindowLongW(hwnd, GWL_EXSTYLE)
            style = style & ~WS_EX_TOOLWINDOW
            style = style | WS_EX_APPWINDOW
            res = windll.user32.SetWindowLongW(hwnd, GWL_EXSTYLE, style)
        self.wm_withdraw()
        self.wm_deiconify()
