How to build a QR Reader App? [closed]

Question

I want to make an app that has a this simple functionality; it reads a qrcode image using my webcam and output whatever is in the code as keyboard strokes. I found this library, libdecodeqr-examples

and it looks like something I can definitely use, it also has a simple command line application, libdecodeqr-webcam, that does something similar to what I want. So my question is how do I build a GUI app using Quickly that does more or less the same thing but in my case the output is given as keyboard input?

Also if I do need to use libdecodeqr-examples in my quickly app how do I do it?

Answer 1

You can use python code to call commandline from quickly (which uses python basically) for example, check code below

from subprocess import call
call(["ls", "-l"])

let me know if it helps, good luck.
