# qr_component

This component uses Javascript libraries and Offscreen web areas to generate QR Codes.

This component works with 4D v19+ (requires Offscreen web areas).

Two libraries are used (and packaged in the component)

```4d

   // Before 4D v19R5

var $vt_text : Text

$vt_text:="Hello"

var $qrCode : Object

$qrCode:=qr_qrCodeShimNew($vt_text) 

var $picture : Picture

$picture:=$qrCode.generate()

  // in 4D v19R5+

var $vt_text : Text

$vt_text:="Hello"

var $qrCode : cs.qrcode.qrCodeShim

$qrCode:=cs.qrcode.qrCodeShim.new($vt_text)

var $picture : Picture

$picture:=$qrCode.generate()

```
