I'm looking to do floating touch -- hover the phone screen up to few millimeters without touching it.
Not sure how it is called. I don't know the name of the class/techno to use that's the reason why I posted the behavior which is to be able to hover the screen with your hands/fingers without touching it.
Can I accomplish that using Qt on Android?
For example: in a mobile phone, instead of taping "Settings" to access/open setting options, you just hover your finger over "Settings" then it act as you tapped it. That's what I want to accomplish.
Sony implemented Hover up to 22mm away (https://www.theverge.com/2012/3/14/2871193/sony-xperia-sola-floating-touch-hover-event-screen-technology)
