Qr

The QR object displays a QR code that can be scanned with a mobile device to open a specific URL.

HSYCO URLs can also be encoded in the QR code, allowing users to open a project and send commands to the project when the QR code is scanned.

Attributes

Common

ID

Sets the object's ID.

The ID identifies the object and is used to reference it in UISet actions, allowing to change its attributes dynamically.

The ID is not unique, it can be shared among multiple objects to quickly change a common attribute.

IDs can't be changed with a UISet action, but they can have a Value Binding assigned to them. Value Bindings on IDs allow an object to be dinamically attached to a set of attribute values.

E.g. the following Value Binding switches the ID of the object between mybutton1 and mybutton2 based on the value of the UISet button.address:

Value binding: ="mybutton" + ui('button', 'address')

UISet: UISet('button', 'address', '1') switches the ID to mybutton1 UISet('button', 'address', '2') switches the ID to mybutton2
