The situation has changed with the upcoming 3.0 release. There is a new feature complete Qt wrapper (single header) and a new QWidget based demo app (still called ZXingQtCamReader). I suggested to Boyuan to include that (in some form).
This program runs on a live video feed and detects and displays (multiple) barcodes. It also allows you to do some basic configuration. What it currently does not is helping actually getting the scanned content out. So I'd argue, it is a good showcasing app but not really useful, yet. Any suggestions on how to export the barcode content? The first thing coming to my mind is a "copy to clipboard" button that either copies the content of the barcodes that are detected at the moment of pressing the button or an internal log that simply collects all detected codes since startup. - Axel
