I am starting with QT-Designer/C++ and I am absolute beginner... Have a Zebra scanner library for a barcode scanner that I would like to use to create a scanner app. In Visual studio I can simply add this reference by clicking on add. Under COM libraries I find it and simply add it. How to do the same in QT-Designer? Sorry, in case this is a stupid question. Thanks!

    Qt Designer has nothing to do with COM. It is a user interface builder. Commented Dec 20, 2016 at 16:55
  • OK, Thanks. In Visual Studio I can add it from add/reference. I see there an item called CoreScanner. I think it is an .exe file that was installed in driver installation process. How can I open that in qt_c++ and use it? Commented Dec 20, 2016 at 17:45

    Qt itself is able to use COM but that is programming without any designers. QAxObject, QAxWidget, dumpcpp, lookup those words. Or, if the compiler is MS VC++ you can just use ATL technique with #import statement immediately in your code. That is complex, right. Adding references to projects sounds more like C# experience.
