How to pin a pygame window on top?

In Pygame, there is no built-in functionality to pin a window on top of other windows. However, you can achieve this behavior by utilizing platform-specific functions or external libraries. Here are two approaches you can consider:

1. Using Platform-Specific Functions:
   If you're running your Pygame application on Windows, you can use the SetWindowPos function from the ctypes module to set the window's position and z-order. Here's an example:

   pythonCopy code
   import ctypes
   
   import pygame
   
   
   
   pygame.init()
   
   
   
   # Create the Pygame window
   
   window_width = 800
   
   window_height = 600
   
   screen = pygame.display.set_mode((window_width, window_height))
   
   
   
   # Get the window handle
   
   hwnd = pygame.display.get_wm_info()["window"]
   
   
   
   # Set the window's z-order to always on top
   
   ctypes.windll.user32.SetWindowPos(hwnd, -1, 0, 0, 0, 0, 0x0001 | 0x0002)
   
   
   
   # Run the game loop
   
   running = True
   
   while running:
   
       for event in pygame.event.get():
   
           if event.type == pygame.QUIT:
   
               running = False
   
   
   
       # Game logic and drawing here...
   
   
   
       pygame.display.flip()
   
   
   
   pygame.quit()
   
   

   This code sets the Pygame window's z-order to be always on top using the SetWindowPos function. Note that this approach is specific to Windows and relies on the ctypes module.

2. Using External Libraries:
   Another option is to use external libraries that provide window management features. One such library is pygetwindow, which allows you to manipulate windows. You can install it using pip:

   Copy code
   pip install pygetwindow
   
   

   Here's an example of using pygetwindow to pin a Pygame window on top:

   pythonCopy code
   import pygetwindow as gw
   
   import pygame
   
   
   
   pygame.init()
   
   
   
   # Create the Pygame window
   
   window_width = 800
   
   window_height = 600
   
   screen = pygame.display.set_mode((window_width, window_height))
   
   
   
   # Get the Pygame window's title
   
   window_title = pygame.display.get_caption()[0]
   
   
   
   # Set the Pygame window to be always on top
   
   gw.getWindowsWithTitle(window_title)[0].setAlwaysOnTop(True)
   
   
   
   # Run the game loop
   
   running = True
   
   while running:
   
       for event in pygame.event.get():
   
           if event.type == pygame.QUIT:
   
               running = False
   
   
   
       # Game logic and drawing here...
   
   
   
       pygame.display.flip()
   
   
   
   pygame.quit()
   
   

   In this example, pygetwindow is used to get the Pygame window by its title and set it as always on top using the setAlwaysOnTop method.

   Note that using external libraries may introduce dependencies and may not be as platform-agnostic as the first approach. Make sure to handle any potential issues or limitations specific to the library you choose.

Choose the approach that suits your needs and platform requirements.
