pygame get window position

[vskarica]

Hi!
This seems like an obviously asked and answered and if so, I apologize. However, I cannot seem to be able to find the answer, and I have lost a few days searching.
So, I am trying to get current position of pygame window on physical screen in order to set other forms positions accordingly.
It would also bi nice to be able to set position and detect movement of window, but it’s not critical for my project. Not at this point anyway.
All I found was:

1 2	import os os.environ['SDL_VIDEO_WINDOW_POS']='%d,%d' %(x,y)

Please help!

Most of the time pygame is used as the sole GUI. It is not ideal to use with tkinter as people often do, for example. Pygame is designed to be the sole GUI while playing a game, not mixed with other GUI to be positioned on the monitor.

1	os.environ['SDL_VIDEO_WINDOW_POS']='{},{}'.format(100,200)

this sets the environmental variable for SDL which pygame uses to position the window in that spot. However this variable is static....it does not change as you move the window. It is only useful for setting the initial location of the window to be spawned.

All of pygame.display methods are pertaining to the window itself, is current size and width, etc. not its location on the screen.

To be honest you may have to ask the developers on this one.

Thank you for your answer.
I figured as much. It is too obvious a question to not have an answer somewhere however incompetent searcher one might be.

Getting info about the container window is a little outside pygame's scope. But that doesn't mean it's not possible, you just have to reach into other, more platform-specific avenues.

On Windows, you can get the info using ctypes:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

import pygame as pg import ctypes from ctypes import wintypes     def build_win_info_function():     # api docs: https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getwindowrect       # describe the windows api function we want     # GetWindowRect returns a bool (success/fail), a window handler (HWND),     #  and a pointer to a rect (which the ctypes module will return to us)     builder = ctypes.WINFUNCTYPE(         wintypes.BOOL, wintypes.HWND, ctypes.POINTER(wintypes.RECT)     )       # 1==we're passing this in, 2==ctypes is passing it back to us     flags = ((1, "hwnd"), (2, "lprect"))       # now that we've described the function, we indicate where it exists so we can call it     func = builder(("GetWindowRect", ctypes.windll.user32), flags)     return func     def main(window):     # pygame tracks the window handler, and makes it available     window_handler = pg.display.get_wm_info()["window"]     # build a GetWindowRect     get_window_rect = build_win_info_function()       position = {"top": 0, "left": 0, "right": 0, "bottom": 0}     last = None     while True:         # pump events, so the window can move         for ev in pg.event.get():             # close window event             if ev.type == pg.QUIT:                 return           # get the current window info         window_info = get_window_rect(window_handler)         position["top"] = window_info.top         position["left"] = window_info.left         position["right"] = window_info.right         position["bottom"] = window_info.bottom         # only print on updates         if last != position:             print(position)         # copy(!!) the position         last = {**position}     if __name__ == "__main__":     # setup pygame     pg.init()     # create a window     win = pg.display.set_mode((600, 200))     # run main loop     main(win)

If you're NOT on Windows, there's almost definitely a way to do it. I just wouldn't know what it is haha.
