Hello, it seems to be possible to interact with the host system through dedicated code. QT code I suppose. Could you describe how it could be possible to (e.g.) put the system to sleep or change its volume?
ProMultitouch uses QML ( http://doc.qt.io/qt-5/qmlapplications.html). It it is not allowed to change the system settings. But you are able to run external apps and .bat scripts.
See an example in the attachment. It uses User code feature ( https://docs.promultitouch.com/reference/inspector/interaction_inspector.html).
