stuff like that is always possible - and ctypes is usually the best way
to do little hack stuff like this in python.
For getting the window pos, the function "pygame.display_get_info" gives you
a dictionary with "window" set the HWND of your window, and the OS function
"GetWindowRect" can be called on that HWND to get the window position/size
The code below is getting the pygame window's position just fine for me on
windows:
---------------------
import pygame
from ctypes import POINTER, WINFUNCTYPE, windll, WinError
from ctypes.wintypes import BOOL, HWND, RECT
_prototype = WINFUNCTYPE(BOOL, HWND, POINTER(RECT))
_params = (1, "hwnd"), (2, "lprect")
GetWindowRect = _prototype(("GetWindowRect", windll.user32), _params)
def _errcheck(result, func, args):
if not result:
raise WinError()
return args
GetWindowRect.errcheck = _errcheck
def GetPygameWindowPos():
info = pygame.display.get_wm_info()
window_id = info["window"]
r = GetWindowRect(window_id)
return (r.left, r.top, r.right, r.bottom)
pygame.display.set_mode((400,400))
print GetPygameWindowPos()
