In QML I'm using Screen.pixelDensity So a minimum width of touch area is about Screen.pixelDensity*7, which will be 7 mm in pixels, and the number comes from some old Nokia ergonomics study.
Now some low end Android devices report bogus values, suffering from illusions on grandeur, but it seems to be working fairly well for most devices, including iOS. A related issue is that I haven't yet found a way to make Google Play "designed for tablets" working with Qt though. So I don't know how I make a Qt app so that Google Play considers it tablet ready. It requires some heuristics with resources / layouts, screen shots are not enough. Any help there is appreciated. Hope this helps, Harri On 12/03/2015 12:03, Nuno Santos wrote: > Hi, > > I have developed an app using fixed measures in pixels for certain parts.
