It also works with each type of window.
Code like this:

def handle(hwnd: int, msg: int, wp: int, lp: int) -> int:
        if msg == WM_NCCALCSIZE and wp:
            lpncsp = NCCALCSIZE_PARAMS.from_address(lp)
            lpncsp.rgrc[0].top -= 6

        return windll.user32.CallWindowProcW(*map(c_uint64, (globals()[old], hwnd, msg, wp, lp)))

old, new = "old_wndproc", "new_wndproc"
prototype = WINFUNCTYPE(c_uint64, c_uint64, c_uint64, c_uint64, c_uint64)

globals()[old] = None
globals()[new] = prototype(handle)
globals()[old] = windll.user32.GetWindowLongPtrA(self.hwnd, GWL_WNDPROC)
windll.user32.SetWindowLongPtrA(HWND, GWL_WNDPROC, globals()[new])

Hello, I really appreciate your suggestion for removing the 6px frame that appears after using the titlebar.hide function. However, I tried to implement your code and I encountered some errors and issues. Could you please be more elaborate on how your code works? Alternatively, you could open a pull request with the suggested changes, and I would be happy to review it and test it.

Thanks! I may take time to test it. I used this code in one of my repo: https://github.com/littlewhitecloud/CustomTkinterTitlebar
