🔒 PySide6 Frameless Window Snap Problem...

[oblique thicket]

I launched a Frameless Window using PySide6. I'm trying to use the Windows 10 OS Snap feature (snapping to the top, left, or right of the monitor), but it's not working. How can I fix this?

Hey @oblique thicket!

Please edit your message to use a code block

Add a py after the three backticks.

```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```

if its super long, use a paste service

I have included it in an executable form only.
Minimum code to open a window.
I want it to snap on Windows 10.

how do you mean it doesn't snap?

Does any other app on your pc do the window snap when you drag it to the edges/border?

@oblique thicket it works for me. no code change whatsoever

[oblique thicket]

wait a m pls

[oblique thicket]

Hmm, I have confirmed that it works well in my environment as well.

Previously, it wasn't working properly, so I requested that some content be deleted to post this question. However, it seems to be working well now just by doing that.

For now, I will verify this myself using this file.

Thank you for your help.
