the following did th trick!
Not sure why it doesn't work when I pass the parent handle directly to
CreateWindowExW. Setting teh style to WS_CHILD also makes it not
work. but this works for my purposes.
self._hwnd = _user32.CreateWindowExW(
self._ex_ws_style,
self._window_class.lpszClassName,
u'',
WS_POPUP,
CW_USEDEFAULT,
CW_USEDEFAULT,
width,
height,
0,
0,
self._window_class.hInstance,
0)
win32gui.SetParent(self._hwnd, self.parent_hwnd)
