Struct Press 

pub struct Press {
    pub at: Point,
    pub threshold: f64,
}

The press a gesture began with.

Fields

at: Point

Where it landed, in surface pixels.

threshold: f64

How far it has to travel to become a drag.

Implementations

impl Press

pub const fn new(at: Point, threshold: f64) -> Self

pub const fn from_pointer(at: Point, coarse: bool) -> Self

A press from a pointer that reports its own position precisely, or not.

pub fn is_drag(self, now: Point) -> bool

Whether the pointer has travelled far enough for this to be a drag.

pub fn is_drag_in_world(self, moved: f64, zoom: f64) -> bool

The same question for a pointer tracked in map coordinates, where the threshold still means screen pixels however far the view is zoomed.
