Qml does not provide a clear and flexible mechanism for separating user interface behavior depending on the input method.
In a ListView, it is difficult to implement different gestures and triggers to interact with items in the delegate at the same time (mouse and touch screen - left click, right click, drag, scroll, long press).

For example, the pressDelay property is independent of the input device.

It would be nice to have a different properties for TouchScreen and Mouse (and possibly TouchPad).

And to implement that behavior, we should have to use an incomprehensible and tricky solution.
