How do I get the HWND of a window made with tkinter?

Question

How to get the HWND of a window made with tkinter?

I have already tried this:

print(root.winfo_id())
print(getAllWindows())

However, there is no root.winfo_id() in the list of getAllWindows() Why so?

You can use `pywin32` module in Windows platform: `win32gui.GetParent(root.winfo_id())`. — acw1668, Jan 23 '22 at 16:53

This code:

   hwnd = root.winfo_id()
   parent_hwnd = win32gui.GetParent(hwnd)
   text = win32gui.GetWindowText(parent_hwnd)
   print(text)

it will return "System menu", which means it is what you want. Apparently there is a wrapper This simple window coded in PySimpleGUI;

have the following windows (as shown by Spy++) :

The first window in the list is the one we catch (it as 'System menu' as title bar!)
