How to use close_callback? #307

Closed SaranSundaresan closed 4 years ago

SaranSundaresan commented 4 years ago

HI. When I close my existing eel window, the python program still remains executing. Moreover, the localhost instance still remains active. I need to find a way to close the localhost instance and also the python program, if required, at the same time that I close the eel window.

I believe close_callback will help me accomplish the above objective. But I'm getting the syntax wrong and I'm unable to understand the syntax well enough from the doc. Pls help!

If you want to close the application when you close the window, here is the syntax :)

import eel

def close_callback(route, websockets):
    if not websockets:
        exit()

eel.init("web")
eel.start("main.html", close_callback=close_callback)

web/main.html

<html>
    <body>
        <script type="text/javascript" src="/eel.js"></script>
        <div>bouh</div>
    </body>
</html>

The function close_callback takes 2 arguments

Hope it helps

@SaranSundaresan this really shouldn't be happening if you're running the latest version of Eel. Can you share your code, your Python version, and Eel version?

The close callback that @std-odoo kindly shared should already be the default behaviour: https://github.com/samuelhwilliams/Eel/blob/bb058329b64b2f3e8d3e5d0e8a4cd6f3d3eab3b7/eel/__init__.py#L330-L340
