How to pin a pygame window on top?


I need to make a pygame window stay on top of other windows. I found a way to do so on this discussion:

How to make python window run as "Always On Top"?

But this doesn't work in my python code.

Here is my code:

# Imports
import pygame as pg
from ctypes import windll

SetWindowPos = windll.user32.SetWindowPos

pg.init()
win = pg.display.set_mode((200, 30))

x, y = 100, 100
# Pin Window to the top
SetWindowPos(pygame.display.get_wm_info()['window'], -1, x, y, 0, 0, 0x0001)


#Main Loop
run = True
while run:
    for event in pg.event.get():
        if event.type == pg.QUIT:
            run = False
            break

Solution

  • For ctypes.windll to work, you have to first configure the types of the function's arguments (IIRC you don't have to this if you're on a 32-bit machine).

    So your code should look like this:

    import pygame
    import ctypes
    from ctypes import wintypes 
    
    def main():
        pygame.init()
        screen = pygame.display.set_mode((400, 200))
        
        hwnd = pygame.display.get_wm_info()['window']
        
        user32 = ctypes.WinDLL("user32")
        user32.SetWindowPos.restype = wintypes.HWND
        user32.SetWindowPos.argtypes = [wintypes.HWND, wintypes.HWND, wintypes.INT, wintypes.INT, wintypes.INT, wintypes.INT, wintypes.UINT]
        user32.SetWindowPos(hwnd, -1, 600, 300, 0, 0, 0x0001)
        
        while True:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    return
            screen.fill('grey')
            pygame.display.flip()
    
    if __name__ == '__main__':
        main()
    

    I prefer to use the pywin32 package instead, because the functions just work and the constants you need are available.

    import pygame
    import win32gui
    import win32con
    
    def main():
        pygame.init()
        screen = pygame.display.set_mode((400, 200))
    
        hwnd = win32gui.GetForegroundWindow()
    
        win32gui.SetWindowPos(hwnd, win32con.HWND_TOPMOST, 600, 300, 0, 0, win32con.SWP_NOSIZE)
        
        while True:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    return
            screen.fill('grey')
            pygame.display.flip()
    
    if __name__ == '__main__':
        main()
