This repo produce a QML Module with custom types that can detect and decode QRCODEs.

The types should be style independent, but the colors used relies on the EstervDesigns Simple style. If you want to change the colors in your top qml file one can do

import Esterv.Styles.Simple
...
 
Component.onCompleted:
{
Style.frontColor1= (Style.theme)?LightThemeColor:DarkThemeColor//Like control.palette.text
 
Style.frontColor2= ... 
Style.frontColor3= ... 
 
Style.backColor1= ... 
Style.backColor2= ... 
Style.backColor3= ... 
}

The detection and decoding is performed by OpenCV libraries. In case OpenCV is not found on your system CMake will download pre compiled libraries from my action releases.

The library use QtMultimedia if not compiling for wasm. If compiling for wasm the library creates a custom ImageProvider that communicates with the browser.

You can play with the decoder on this page
