Pygame set window on top without changing it's position

问题

As I found in the following topic : How to make python window run as "Always On Top"?

I know how to put a window on top. But I would like to keep it at the same position. The autor says that he found a work around to find the x and y values. I would like to know how I can achieve that !

How can I get the x, y values of a pygame window ? Maybe it's a wrong way of doing.

The effect I am looking for is that the window goes on top when I trigger it with some function call.

For those who know League of legends, when a game starts, the window goes on top and remains at the same coordinates.

I found a solutions thats seems pretty well done :

#!/usr/bin/python
# -*- coding: utf-8 -*-


from ctypes import windll, Structure, c_long, byref #windows only


class RECT(Structure):
    _fields_ = [
    ('left',    c_long),
    ('top',     c_long),
    ('right',   c_long),
    ('bottom',  c_long),
    ]
    def width(self):  return self.right  - self.left
    def height(self): return self.bottom - self.top


def onTop(window):
    SetWindowPos = windll.user32.SetWindowPos
    GetWindowRect = windll.user32.GetWindowRect
    rc = RECT()
    GetWindowRect(window, byref(rc))
    SetWindowPos(window, -1, rc.left, rc.top, 0, 0, 0x0001)

Now to put a window on top, simply call onTop(pygame.display.get_wm_info()['window']) to handle your pygame window.

There's a shorter solution using the same function:

from ctypes import windll
SetWindowPos = windll.user32.SetWindowPos

NOSIZE = 1
NOMOVE = 2
TOPMOST = -1
NOT_TOPMOST = -2

def alwaysOnTop(yesOrNo):
    zorder = (NOT_TOPMOST, TOPMOST)[yesOrNo] # choose a flag according to bool
    hwnd = pygame.display.get_wm_info()['window'] # handle to the window
    SetWindowPos(hwnd, zorder, 0, 0, 0, 0, NOMOVE|NOSIZE)

Getting current window position:

from ctypes import POINTER, WINFUNCTYPE, windll
from ctypes.wintypes import BOOL, HWND, RECT


# get our window ID:
hwnd = pygame.display.get_wm_info()["window"]

# Jump through all the ctypes hoops:
prototype = WINFUNCTYPE(BOOL, HWND, POINTER(RECT))
paramflags = (1, "hwnd"), (2, "lprect")

GetWindowRect = prototype(("GetWindowRect", windll.user32), paramflags)

# finally get our data!
rect = GetWindowRect(hwnd)
print "top, left, bottom, right: ", rect.top, rect.left, rect.bottom, rect.right

# bottom, top, left, right:  644 98 124 644

Putting the window on the foreground:

x = rect.left
y = rect.top
import os
os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (x,y)
