Ubuntu Phone Tabs layout with Slider component

view story

http://askubuntu.com – I'm writing an app for Ubuntu Phone with QtQuick and Ubuntu Components. I have multiple tabs layout (New Tabs) and a horizontal Slider. When I move the slider, the tabs switch too. Is there a way to disable this, so I can set slider to a value without switching tabs. There's an example of this in PhoneComponentShowcase.qml. Try moving the slider around and notice tabs also moving. Can I call event.preventDefault() or stopPropagation() functions? (HowTos)
