Window does not appear centered on screen

[PPicku]

When creating a window, it does not appear in the center of the screen, but rather in the top-left corner or elsewhere. This issue did not occur in version 5.4. I also couldn’t find any documentation mentioning a new function or method for centering windows.

I’m not sure if this is an issue on my side; if it is, I sincerely apologize.

My code:

import webview

if __name__ == '__main__':
    window = webview.create_window('browser', 'https://example.com')
    webview.start()

It seems the issue hasn’t been fixed yet; I’m experiencing it as well.
I’m on Windows 10 using PyWebView version 6.1.

A workaround is to use screeninfo and create a function like this to get the screen dimensions and center the window manually:

@staticmethod
def center_window(window, width, height):
    try:
        monitor = get_monitors()[0]
        x = (monitor.width - width) // 2
        y = (monitor.height - height) // 2
        x = max(0, x)
        y = max(0, y)
        window.move(x, y)
        print(f"Window centered at: x={x}, y={y} (Screen: {monitor.width}x{monitor.height})")
    except Exception as e:
        print(f"Error while centering window: {e}")

Then you can register this function as an event handler.
