yet I did not use it but I have onlu some helpful links which have some api for scanning and viewing the qrcode in cascades development.

QrCodeScanner

You can use zxing library to read QRcode.

[sanjeevtmimt]

can you provide a demo application of zxing library which can use to scan QRCode?

I'm working on a demo using ZXing to scan multiple barcode formats right now, but if all you care about is QRCodes the built in QRCode scanner classes work fine.

Hello,

This is the example how you can read a QRcode image.


QFile file(path);
qDebug() << path;
QImage qimage = QImage();
if (file.exists()) {
qimage.load(path, "PNG");
} else {
return "";
}
if (!qimage.isNull())
qDebug() << " file found and loaded " << qimage.height()
<< qimage.width();
else
return "";
Ref<LuminanceSource> imageRef(new CameraImageWrapper(qimage));
Ref<Binarizer> binarizer(new GlobalHistogramBinarizer(imageRef));
Ref<BinaryBitmap> _image(new BinaryBitmap(binarizer));
// Tell the decoder to try as hard as possible.
DecodeHints hints(DecodeHints:EFAULT_HINT);
hints.setTryHarder(true);
// Perform the decoding.
QRCodeReader reader;
Ref<Result> _result(reader.decode(_image, hints));
// Output the result.
qDebug() << _result->getText()->getText().c_str() << endl;


For this you need to add library of ZXing.

Thanks.

Actually, it depends on what platform is the QR Code barcodes are created in. If the QR Code barcodes are created in Java, you can google "Java QR Code barcode reader guide or tutorial", many professional passages like this appear.
