[Flask] Flask Digest, Vol 10, Issue 6

Sun Apr 10 11:25:44 EDT 2016

@nik,

I've taken the time to write something minimal that worked for me. I used
PySide and I've bundled the code to this link https://db.tt/52SCJFG0

I hope you would be able to draw inspiration from it and then make it
happen in your code.
