Can we:
Read, write, display and store QR codes with a Spider Basic Web App?
Can that Web App reside on both Android and IOS devices and be run by the device browser? (i.e. not as mobile apps)

Hi IdeasVacuum ,
here's a simple code to
generate QR-Codes:
Code: Select all
EnableExplicit
Procedure Main()
Protected GID
OpenWindow(0, 0, 0, 220, 220, "CanvasGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
CanvasGadget(0, 10, 10, 200, 200)
GID = GadgetID(0)
! var qr = new QRious({
! element: v_gid.gadget,
! size: 200,
! value: 'https://www.spiderbasic.com/'
! });
EndProcedure
! require(["https://cdnjs.cloudflare.com/ajax/libs/qrious/4.0.2/qrious.min.js"], function(Q) {
! window.QRious = Q;
Main()
! });

Reading QR codes is not particularly complicated either, but it is time-consuming (controlling the camera, reading in the image, etc.). But it can definitely be done with a browser.
Greetings ... Peter
