Can you help me out in getting started? #30

Since, this SDK does not support python natively. Can you help me out in steps to get started with this Zebra Scanner SDK to create applications. Though, I have the developer guide for the SDK but still I am newbie so facing difficulty.

Have a look at the virtual void functions in CoreScanner: https://github.com/dayjaby/zebra-scanner/blob/master/src/BoostPythonCoreScanner.h

These are callback functions, that the Zebra SDK will call when something specific happens (e.g. OnBarcodeEvent gets called when a barcode gets scanned). So our only job is to implement them here in C++. Most callbacks get some XML string that we have to parse for that. The OnBarcodeEvent implementation (https://github.com/dayjaby/zebra-scanner/blob/master/src/BoostPythonCoreScanner.cpp#L438) is very simple:

  1. Find the Scanner s that matches the scannerID in the XML
  2. Convert the hexadecimal datalabel to a normal string
  3. Create a Barcode object o
  4. Do a callback on the python function s.OnBarcode(o)

Do you have more specific questions?

I never used or tested it on windows. This is not a pure python package, it also requires some C++ compiling. If you find a solution for this on windows let me know :)
