In RunTime, the QR Code Scanner widget will appear with a floating toolbar with the following buttons - AutoStart, AutoStop and StartStop.
When the widget is loaded, the camera will start automatically if AutoStart is set to True. To leave the camera on, select AutoStop.
To manually start the camera, select StartStop and scan the QR Code.
The camera will stay on after you scan the QR code, allowing the user to scan additional QR codes. To stop the camera, select StartStop.
The floating toolbar will display the QRCode derived from the QR Code scanned by the camera.
The user can script an action based on the QRCode returned.
